Blue Bird Tile How-to

Bird Tile

Happiness is a garden in bloom. This charming blue bird scene may be small, but it’s just the right size to bring the beauty of spring into your home or garden. Despite the detail, this tile is fast, easy and FUN to make.

Many of my designs originate from drawings I make on my computer in my office. But sometimes I like to go out into my studio and let designs evolve organically. I may have a theme or direction, but not much else. I let my creative mood, the mysteries of glass, and the magic that lives in my studio take over. This freestyle approach is thrilling because it brings a new life back to a familiar art by inspiring unique project ideas.

When creating this piece, I wanted to make a spring time scene including a bird. The rest of the design came together as I worked. The result was a combination of different techniques that gave the garden theme a deeper, more interesting quality. This unusual mix of methods makes this simple design more exciting to create. Plus, it ramps up the intricacy and overall appeal of the finished artwork. This tile size format is a great practice piece. Use it to experiment with innovative techniques that you can further develop to take your projects in exciting new directions.

Most fused glass is built on a plain clear or white glass base. Instead of thinking of the base simply as a platform, consider it an additional place to add to the design. Include details that will enhance the surface design to intensify the visual impact of the artwork. Here, I’m creating lush underbrush, faint leafy accents, and a crisp blue sky to create a cheerful backdrop for my garden scene.

Before you jump in, here are some tips for designing on the base layer.   

Apply only powder size frit on the base glass. This minimizes the number and size of any bubbles that might form.

Use opal, high contrast colors. This ensures the colors are true to the original glass selected and not muddy mixes. It also gives you strong color density that appears solid, not diluted.

Start with the lighter frit colors. Then layer the darker colors on top, in moderation, to ensure the lighter colors show through.

Don’t be skimpy when applying the powders. The frit should cover the white glass completely and evenly. If you question whether you have enough frit, add more.

To make this piece, start by cutting white glass into an 8” square. To make the lush underbrush, sift opal light green powder along the bottom of the glass. Create a graceful arch that reaches up toward the top corners. Be sure to leave room for the sky. Sift opal blue powder to make the sky.

Using the pattern as a guide, cut a fern stencil out of stiff paper with a razor knife. I use a file folder,

or some poster board for my stencils. If handled carefully, these stencils are reusable. Otherwise you can buy a plastic leafy stencil from a craft store.

Place the stencil on the powder-covered glass. Sift opal dark green powder frit over the stencil. Carefully remove the stencil. Dump the excess frit from the stencil on a spare sheet of paper to collect later. Repeat the fern pattern as many times as you like. Be sure to extend a few ferns up into the blue sky to soften the hard edge between the green and blue background. Set the frit-covered glass aside. Place it in a safe location where it won’t be disturbed.

18

 

Cut a piece of clear glass into an 8” square for the design layer.

Use the pattern as a guide to make the flowers. Or, for more organic shapes cut a 3/8” strip of opal orange glass. Cut the strip into 1” pieces. Next divide the orange pieces in half diagonally to make a series of varying sized triangles. Make one rectangular shaped piece per flower for the front petal. Round out the flower petal edges with the grinder. Dry and clean the ground glass. Assemble the flowers on the clear glass layer, as shown.

Using the pattern as a guide cut the bird out of opal blue glass. Grind the cut glass to improve the shape and fit. Dry and clean the bird pieces. Assemble the bird on the clear glass base. Glue the cut pieces to the clear base with fuser’s glue, applying the glue with a toothpick. Use the smallest amount possible to prevent hazing.

13

Bending stringers is fast and fun. Here are some tips to make it easier.

You have to place the stringer directly in the candle flame for it to bend. Put only a little pressure on the stringer. If you push too hard it’ll break instead of bend.

The stringer is hot within one inch of the flame.

The stringer will be a lot hotter than you think, a lot longer than you think!!! Set it aside to cool before cutting it to size.

The black soot left behind by the flame will burn off during fusing.

The advantage to using a candle in the tin cup is it contains the hot wax and reduces messy clean ups.

Noodles can be bent in the candle, but they take more time and patience.

Bend an assortment of stringers into a variety of soft shapes. Leave a few straight for a nice linear look. Arrange the stringers on the clear glass. Use a spoon and add medium frit for the secondary flowers. Use yellow frit for the center of the open flower.

Carefully stack the bird and flower layer on the base layer. Fire to a full fuse temperature using the guide below.

20

Glue two saw tooth hangers using E6000 on the back of the fused glass and hang the tile on a wall.

Or you can slump the glass to make a dish using the optional guide below.

Enjoy your garden in bloom all year long.

Bird of Paradise Flower How-to

Picture2

As seen in my, Painting with Frit Video.

Tropical flowers, with their vivid colors and striking shapes have always been a favorite subject for my glass art. The bird of paradise flower is especially fun. Thanks to its easily recognizable profile, I can render it in fantasy colors knowing the image will remain familiar and be imprinted with my personal, artistic flare.

When planning this project, I imagined the spiky flower petals having blended colors that would add a rounded quality and fullness to the design. I decided glass frit would give me the bright colors and subtle shading I was looking for. I then decided to use a high contrast, solid color background that would showcase the flower.

Frit and cut sheet glass are a great combination for creating dramatic images.

Frit is a terrific filler material, but it’s difficult to establish a hard edge with frit alone. It leaves a fuzzy or blurred line around the individual design shapes. And so, wherever I want strong line quality and solid color saturation I cut the glass shapes out of sheet glass. The cut glass outlines and contains the frit giving my artwork the professional quality crispness I strive for.

Picture3

How to make the bird of paradise flower.

This project is made with two layers of glass. The base layer is clear glass.

The second layer is made up of cut pieces and frit. I started the second layer with a narrow border to visually frame the art and add a nice punch of color.

I selected black glass for the background to contrast the colorful flower petals and plant stem. The background is cut with a saw to minimize the number of pieces and to give me a very clean, accurate shape for the flower. The cut pieces of the second layer are glued to the base layer with a small amount of fuser’s glue.

Tip: Let the glue dry before applying the frit. Otherwise, the cut glass pieces move around during assembly which results in a blurry edge.

Picture1

Select your frit sizes and colors with purpose.

I chose to use fine and medium size frit, in both opal and transparent glasses. I selected bright, eye-popping colors that would contrast the flat black and dance in the light. I apply the frit with a spoon, filling the open spaces to the height of the cut glass surrounding them. Once filled, I grade the frit with a paint brush to blend and soften the colors.

Clean up is key to exceptional quality craftsmanship.

Once I’m satisfied with my frit color mixes and the coverage, I take a small paint brush and clean any overflow off the background glass. I take my time with this step and make sure to remove any excess frit that might distract the viewer from my beautifully detailed flower.

Frit is a fun way to add a painterly quality to fused glass art. I use it to add detail and shading to increase the visual intricacy and attractiveness of my pieces. Applying frit is a fast, easy way to put a personal spin and your artistic touch on your favorite patterns. Go ahead. Give frit a try. The possibilities are endless.

Picture4

Tips for Fabulous Frit Designs

Use different frit sizes to enhance your design.

Cut glass wherever you want solid color and strong line quality.

Use both transparent and opal glasses.

Create a light source.

Apply light colors first then layer dark colors on top.

Blend your colors.

Use dark, high contrast colors to create shadows.

Pile the frit on. Don’t be skimpy.

Plan your frit application. It shouldn’t be random.

Use stringers and noodles to add linear details.

Be meticulous about your clean up.

Wherever you are in your artistic journey you’re doing great! Keep learning, trying new techniques and seeking the support of community. It only gets better.

This Bird of Paradise pattern is one of 6 graceful designs in my, Painting with Frit video now available as a download here on my website.

Sculptural Fused Glass 4-Day Workshop

DSCN4022

Last week I had a blast making sculptural fused glass art with a fun group of creative, enthusiastic glass artists. We jumped right in on day 1 and had free flows firing before lunch. The students then designed, built and loaded 2 more projects in waiting kilns. On day 2, the students changed the shape of their fused glass with saws and then they arranged them on various slumping molds, plus there was time to start another, new project. We kept up the accelerated pace all week. The student’s creativity and positive energy was contagious.

In this Sculptural Fused Glass 4-day workshop the students cut up 32 feet of fusible glass. We fired my kilns 24 times. Rather than describe the fun we had, I’ll show you our productive, innovative and enlightening week in pictures.

Here’s what the students are saying about the class.

Hearts on Fire How-to

Hearts 4
What better way to share the love this month than with dazzling, hand-crafted glass hearts.

You’re going to love these fast, fun, easy-to-make cookie cutter heart table-toppers. Beyond the obvious quick construction time and the design-as-you-go attraction, these little darlings are so much more. These hearts may be small, but they have a lot they can teach us.

The opportunities to gain experience that’ll advance your glass fusing skills and increase your confidence are many. For one, these small hearts are a terrific, easy-to-manage introduction to building thicker projects. In the future, that knowledge can effectively be applied to mold making and glass casting.

One of the things I love about these tiny projects is that I can test different layering techniques and different color combinations on a small scale. Then later, I can confidently use what I learned to make larger more intricate pieces of art. Plus it gets better, I have nicely finished, completed mini pieces of art for my effort.

Ateco Plain Heart Stainless Steel Cookie Cutter Set-6pcs

Quick tips for making beautiful hearts.

Use only high quality stainless steel cookie cutters. Consider the purchase price an investment in your creative future.

Measure the height of the cookie cutters and then cut fiber paper strips accordingly. I cut 1 inch wide strips for my molds.

Line the inside of the stainless steel heart shaped cookie cutter molds with 1/8 inch thick fiber paper. The 1/8 inch material acts as a cushion between the metal and fused glass. It prevents breakage when the metal mold and glass cool.

Hearts 1

Line the inside of the 1/8 inch fiber paper with Thinfire. The Thinfire gives us the shiny, round edge quality we love.

Hold the fiber paper in place with small strips of clear plastic tape. The tape burns off during firing without leaving any trace.

For bright transparent hearts with a lot of depth, use fine, medium and course size frit. Use powder frit in moderation as it causes the hearts to look cloudy.
Use clear, course or medium size frit as a filler between colors to maintain your bright colors and increase the overall transparency of the project.

Hearts 2

Use transparent glass colors for maximum visual depth. Use opal glass colors in moderation.

Fill the heart molds to just below the edge of the fiber paper. Don’t be skimpy, but don’t overfill.

These hearts are small. Therefore, they can be fired to a full fuse temperature using a program for projects 12 inches is size or smaller.

If handled carefully, the 1/8 inch thick fiber paper liner can be reused several times. Re-line the inside with Thinfire every time for the best edge quality.

Try other cookie cutter shapes like dog bones, flowers and stars. Just keep in mind you have to be able to line the inside with the 1/8 inch thick fiber paper. If the design is intricate the stiff fiber paper won’t conform to the shape accurately. It’s okay to use a small amount of clear plastic tape to assist. But it’s not a good practice to rely on the tape to create the entire design.

Crack the Case –Your Guide to What Went Wrong Inside Your Kiln

 

Mystery and magic attract us to glass fusing. It’s the mystery of making something new and the magic of melting materials that hook us. I’ve asked numerous students, and most admit that opening the kiln after firing is their favorite part of fusing glass. We look forward to it with the same childhood glee we have when opening a crisply wrapped gift.

When the project comes out as expected, or sometimes even better, angels sing, unicorns exist and a rainbow glows brightly over your studio. On the rare occasion that the project doesn’t come out well, our disappointment is heartbreaking. We ask why, what was different, where did I go wrong? We rack our brains looking for answers.

All the while, the answer is right there in front of you.

You just have to recognize what your broken glass is telling you.

Let’s take a simple project and break it. Our sample project is made of two full layers of glass, plus an accent layer. The base layer is clear, and the second layer is a pretty purple and the third, partial or accent layer is a pattern glass with hints of purple.

Design1

To better understand why glass breaks, let’s do a little review.

There are two basic stages to the firing process: heating and cooling. During heating we take the kiln from room temperature to 1200° – 1500°, depending on the type of fused effect we want. Glass is sensitive to temperature change between room temperature and 1000°. To avoid thermal shock, which is breakage due to rapid temperature change, we heat the glass slowly from room temperature until we reach 1000°.

Over 1000° we can heat the glass quickly to the desired temperature. At 1265°, the glass will slump and take on the shape of a mold. At 1365° glass sticks together, otherwise referred to as tack-fuse. At 1465°, the glass will completely melt into one smooth piece. This is considered a full fuse. (These are System 96® temperatures.)

Once we have the desired effect, we cool the glass. The process of heating the glass causes stress within the project. We relieve the stress by holding the glass at an annealing temperature for a period of time. This allows the glass in the project to equalize at that temperature. (The System 96® annealing temperature is 950-960°.)

After fusing, during the cooling phase, the glass is sensitive to temperature change from 1000° down to room temperature. And the project now has greater value because it’s almost done. To avoid breakage due to thermal shock, after the annealing hold, we slowly cool the glass down to room temperature.

Read between the lines. 

Heating Breaks

This is an example of what a break would look like if the glass is heated too quickly. The clear base layer and the purple layer broke in two on the way up. They’re visibly separated on the kiln shelf. Yet the accent layer bridges the crack and the project is indeed fused and held together by the accent layer. Layers one and two break because they are larger and therefore have more mass. The greater mass is more sensitive to rapid heat. The accent layer is smaller, less mass and therefore remains intact. A break like this happens inside the kiln. This is a prime example of breakage due to heating the glass too quickly.

Design2

It’s possible to break the project apart and refuse it slower, but the finished product will likely be different from the original design.

The fix: slow down. Heat the glass at a slower rate. I heat projects from 4” coaster size to 12” bowls at a rate of 300° per hour with dependable success.

Cooling Breaks 

Design5

An annealing fracture has a very specific look. It has a tight curve that rolls into a broad gradual curve. (It almost looks like a smile, but not one that any of us would look forward to seeing.) The broad curve is followed by another tight curve. In my experience, the break usually runs vertically through the project. The glass pieces have been fused together and the break is clean through all three layers. The two broken pieces are generally separated by a sizable gap. The gap is evidence of the internal stress in the fused glass. An annealing break can occur inside the kiln or weeks later. This type of break is the result of rushing the annealing time, peeking into a hot kiln or from opening the kiln too early and chilling the glass.

Design5

You can re-fire the broken glass and re-anneal it, but the finished project may have a visible scar where the glass was broken. You can add frit or extra accent pieces to hide the seam.

The annealing temperature for any specific family of fusible material is constant. The length of time a specific project needs to be held at that temperature is determined by the size of the project and the number of glass layers used to make the project.  A large project, like a 12” bowl, will require a longer anneal time then small project like a 1” pendant.

The fix: consult the glass manufacture’s firing guides and be sure to include the appropriate annealing temp and time in your firing schedule. Here’s the hard part. Don’t peek! Or open the kiln below 1000° until it is at room temperature. I anneal projects that are 12” is size or smaller, made with two layers of glass plus an accent, like the example here at 960° for 40 minutes.

Incompatibility Breaks 

Compatibility breaks are really upsetting because they’re so easily avoided. We do our best to sort and organize our glass by COE, but sometimes a mix-up results in a mystery break. Knowing what to look for can save you from having any future accidents.

C.O.E. (Coefficient of Expansion) this refers to the rate at which glass expands and contracts when heated and cooled. Fusing compatible glass has been formulated, manufactured and tested for compatibility. All the glass in a single project must be of the same C.O.E. so they expand and contract at the same rate during firing. If they are not, stress cracks or breakage will result.

Design3

A glass incompatibility break usually has more than one crack and it often happens a short time after the fused glass comes out of the kiln. The materials literally repel each other and so the broken pieces are angular and sharp.

The fix: Pay close attention to the manufactures labels, store materials by C.O.E., clearly mark scrap and work with only one family of fusing compatible products at a time. Don’t trust that materials given to you are compatible unless they’re marked as such.

Refusing the glass is not an option. But if you want to feel better, take a hammer to the project. Then use the pieces to make a mosaic or to line the bottom of a fish tank.

The Dreaded Hole         

The dreaded hole in the project is caused by heating the glass to fast while firing on a very smooth surface like a primed ceramic self or Thin Fire fiber paper. As the glass is heated the perimeter of the project becomes soft first. It seals to the shelf like a suction cup. The air trapped under the glass expands as it’s heated and pushes up on the glass forming a bubble. The glass bubble becomes thin, it pops and heals over at the full fuse temperature.

You can fill the hole and refuse the glass; however, a blemish will be visible in the new piece. If your design is organic the new detail may add interest. But if your pattern is pictorial, and unless the hole is perfectly located to represent the sun, not so much.

Design4

The fix: add a segment to your firing schedule. In the heating phase of my firing schedule I have a hold at 1300 ° for 60 minutes. Holding at this temperature softens the glass in the entire project uniformly. This extra step is well worth the wait as it eliminates inconvenient eruptions and those nasty holes.

Heart-breaks 

Fortunately, the fusing spirits grant me many successes and very few mishaps. But every so often, no matter how hard I work, through no fault of my own, a single project or piece seems destined to failure. My general rule it to try to rework or salvage a failed project once and on special rare occasions twice. If at that point I’m not happy with my results I abandon the piece and start over from scratch. Hard earned experience has taught me, additional efforts are a waste of time and resources. My best advice when that happens is, let it go.

Here’s a quick example. I was building a huge 12 foot by 16 foot wall sculpture with 14 fused glass circles ranging in size from 12 inch to 48 inch across. All of the glass was special ordered from Uroboros. It came in a single crate. Five of the circles were made with the same color glass. All of the pieces were fired in the same kiln using the same firing program.

For some unknown reason, one of the five circles broke into two pieces after fusing. It cracked as neatly as an egg. No problem, I re-fired the two broken pieces onto a new, single piece of clear. I opened my big clamshell kiln, when it was at room temperature, the re-fired glass looked great. Happy with the result, I went back to my worktable a few feet away.

It never happened before and hasn’t happened since. I was alone in the studio, just me and my glass.

Out of nowhere, the lid on the clamshell came crashing down. I rushed over to the kiln and opened the lid. No big surprise, the fused glass circle was broken and in two neat pieces again. Dam isn’t the only word I used. My rapid fire expletives would’ve made a sailor blush.

I got even by dumping the uncontrollable pieces in the trash. Nope, I didn’t even trust them in a smaller project. Bye, bye! I made a totally new circle and it’s still intact ten years later.

With luck, this is the first time you’ve been introduced to these various ways that glass can misbehave. Hopefully, you’re now armed with the knowledge to avoid such disappointment.

You can confidently explore more in-depth techniques and more advanced projects.

But for added safekeeping, before closing the lid on my kiln I blow kisses to my darlings. You might try it.

Happy Fusing!
