Making a Floral Former Vase

Initial kiln setup. A glass square is first fully fused and cooled, and any coldworking of the edge that is needed is done at this time, It is then placed in the kiln for slumping. In this example the glass is 1/4" thick, and placed shiny side up.

(This is actually a different piece then in the photos below.)

You have to watch carefully while you do this. Find a temperature where the glass just starts to droop, such as 1050F and hold for 15 min. Keep adding temperature in 50 F increments, until you see movement. Then, hold it there, and keep checking until it has folded to the degree you want.

The specific temperature needed will depend on the type of glass, the color, the size and thickness, distance from the elements, and the particular kiln

I don't remember what temperature I used in this tutorial, but with Bullseye glass, I'd start at 1050-1100F.

Note how glass slumps and folds during the heating process


Make sure to stop the slumping process before the tips of the glass touch the kiln shelf or they will flatten out and lose their gloss.
