Can you fuse glass in a silicone mold?
There is no need for high-temperature ceramic molds or the use of any glass binders. Molds can be made of any flexible material, such as silicone, plastic, etc. Your 3D glass pieces fuse on a flat kiln shelf at about 1300 degrees F soaked for 20 minutes.
How do you get bubbles out of fused glass?
If glass is heated too rapidly, the edges of larger pieces can soften and fuse before their interiors do. This earlier fusing of edges may trap air between layers, resulting in bubbles. You can reduce unwanted air bubbles by adding a pre-rapid heat soak to the firing cycle.
What is Freeze and fuse glass technique?
Freeze and Fuse is the method of taking wet powder glass, mixing it with water then packing it into a mold of some kind so it forces all the water to the top, which is then blotted off with a paper towel. The mold is then put into the freezer for about an hour until the wet powder is frozen solid in the mold.
How do you remove devitrification of fused glass?
If your glass is flat, you can sift a very thin layer of Clear powder (about 2 grains thick) over the entire piece and fire it to 1425°F (774°C) – 1450°F (788°C) for about ten minutes, depending on your kiln. This should remove the visible presence of devitrification.
How do you prevent bubbles in glass painting?
To get rid of bubbles, pour the paint out on a separate piece of glass, using it as a palette. Bear in mind that the paint must be used fast once it is opened as it tends to dry up very quickly. You can also drop a small amount of colour on the spaces that need to be painted and quickly brush over the area.

What material is used for glass molds?
Molds. You can make your own molds using a combination of plaster and silica. Mix equal parts by weight of plaster, silica, and water together until it has the consistency of heavy cream. Plaster gives the mold support and silica has a high refractory, so it can withstand a lot of heat.
