Creative Slumping – Drop Out Vase How-to


Excerpt from Creative Slumping Webinar 

My favorite thing about glass fusing is its limitless possibilities. Beyond the basics, there are countless ways to work with this medium and get surprisingly unique results every time. There’s always something new to try and learn.

Another thing I love about glass is the three-dimensional aspect. We have the power to change the shape of our art and take it from flat to fabulous. Drop out molds are great props you can use to express your artistic flare in exciting, new creative ways.

What makes drop molds different?

When fused glass is slumped into a typical mold, we retain the original design unchanged but now with a gentle three-dimensional shape. Whereas the process of reshaping glass by allowing it to fall through the hole in a drop out ring changes and adds to the visual features of the design. As the glass drops through the ring the design elements blend and stretch which gives the illusion of movement in the finished project.

Drop Out Vase How-to

Drop-out-mold vases are tricky. Every kiln fires differently. The type of glass used and the way the project is assembled both affect the way the glass falls through the hole. Taking detailed notes is especially important if you want consistent results time-after-time.

Design Tip: As the glass falls through the mold it stretches. Because dropping glass adds detail to the pattern, I’ve found that when it comes to the vase design less is more. Keep the design simple. An over complicated pattern makes the vase look clumsy and heavy instead of graceful and light.

To make the glass. 

Cut five (5) 7-inch glass circles. Vary the design on the layers. Stack the 5 layers in the kiln on a primed or fiber covered shelf. Wrap the stacked glass with Thin Fire fiber paper and 1/8” thick fiber paper to maintain the desired thickness and shape during the fusing process. Hold the fiber paper ring in place with kiln posts.

Fire to a full fuse temperature using the guide below.

To Make the glass base and riser.

Base: Cut two 4-inch circles, one black glass, one clear dichroic glass. Stack and full fuse.

Riser: Cut two 1 ½ inch circles out of clear glass. Stack and full fuse.

The round, ceramic drop out mold is 9-inch-wide with a 5-inch-wide hole. Cover the mold top with 1/8-inch thick fiber paper. This keeps the glass from slipping off the mold as it drops. If handled carefully, the fiber paper can be reused over and over.

Support the mold with four, 5-inch-tall kiln posts. Cover the kiln bottom, below the glass with fiber paper.

Fire the glass to drop it through the mold using the firing guide below.

Kilns fire differently.

Test fire these guides. Take notes and make adjustments as needed.

  1. Have you ever done a dropout with a 1” thick piece of glass?

    1. The thickest I have done is 3/4″ glass.
