A scan of the World Wide Web in "Slumping" will provide you with a multitude of templates for this method, although not a great deal of data. What is the fall and how is it done?
This is a word used for glass that has been heated so that it becomes soft and begins to bend and fall. Typically this is done fit. Although it is done over articles, it is called draping.
The glass begins to curve and sink at nearly 1,200 to 1,300 degrees Fahrenheit. This procedure can be accomplished with a single glass unit but is commonly accomplished with multiple sections. You first fuse several sections collectively into what is called a complete fuse before bending it into a shape.

Since these pieces of glass have been fused into one, they are shaped to match the mass and volume of the oven-washed mold you plan to use. The finished part is then placed in a mold or facade, and placed back in the oven, and heated until they descend to the primed profile.
There are a large number of molds that can be used for this process. These can be purchased in almost every dimension and structure you can think of, and for just about any celebration you want to observe.
Start by deciding what you would like to compose. Choose your mold and cut out your glass. The glass should be smaller than your shape. Please note that the final piece will roughly match the volume of the glass that you place in this mold.
Try to assemble your glass roughly the same size as the plaster. If it is built larger than your plaster, it will not only sink into the mold, but it could fall on the outside of your mold, trapping the mold in the glass.
