How do you do glass slumping?
In the glass slumping process, the sheet glass is laid over a mold and put in a kiln up to 1300 degrees Fahrenheit. As the glass is heated, gravity pulls it down into the mold. Once the glass assumes your desired shape in the kiln, it is slowly annealed and brought back to room temperature.
What is a slumping mold?
Slump molds are concave forms that work just like other molds in that clay is draped over the surface of the mold. With slump molds, the inside surface of a pot is exposed, while the outer face is in contact with the mold.
How do you slump glass in a kiln?
Fire the kiln to a temperature between 1200 to 1300°F (648.9 to 704.4°C), keeping an eye on the glass through the peephole. The glass will begin softening and turn glossy when the temperature nears 1000°F (537.7°C) and start slumping as it nears 1200°F (648.9°C). Make notes of temperature and slumping time.
What are slumping molds made of?
This example explains how molds are made from clay. There are two basic types of molds in glass slumping. Hump molds are used to form the interior of the slumped glass. The glass sheet or piece is placed on top and slumps over it, it at the right temperature assuming the same shape.

What are glass fusing molds made out of?
People have used molds for glass casting from ancient to modern times. These molds were most often made of sand, special plaster, metal, or graphite. The graphite and metal molds were expensive to produce and required specialized equipment.
Can you use ceramic molds for glass?
Ceramic molds for glass are a simple way to create beautiful glass artwork. Our ceramic molds are easy to use and can be fired multiple times.
How do you make a glass blowing mold?
Glass Blow Mold Begin with a paper shape. Fill the paper shape with microcrystalline wax. Fix the gate (spru) of the shape to the table. Build a box around your shape with coddles and clamps. Heat the mold to 1000ºF and blow glass into the void! Once glass is annealed gently remove mold from glass.
Can I melt glass with a propane torch?
A kiln is necessary to raise the temperature of glass to 1400 to 1600 degrees, while a blow torch can raise the temperature of glass to approximately 900 degrees. Ignite the flame on your propane blow torch. The glass will become pliable and begin to melt.
How do you heat glass without breaking it?
There are two ways to safely melt glass without a kiln: lampworking and using a microwave kiln. Lampworking involves the use of a torch to melt glass to the point of being easily manipulated. A microwave kiln melts glass effectively for small fusing projects.
At what temperature does glass break?
When heated, thin glass begins to crack and typically breaks at 302–392 degrees Fahrenheit. Glass bottles and jars are usually not affected by ambient, refrigeration or warm temperatures. However, high heat (>300°F) and excessive thermal variations can cause glass to shatter or break.
