Do you need a kiln for lampworking?

There are two reasons you would need a kiln designed for Lampworkers:

When you are done working the bead in a torch, you need to cool your bead slow enough so it will not thermal shock and crack. A kiln will easily do this. It is important to note that you may still have stress in the bead even if you have cooled the bead successfully without cracking. The glass bead must also be properly annealed. Annealing the glass bead is accomplished by holding the bead at a particular temperature for a particular period of time. Only a kiln will do this. The temperature depends on the type of glass you are using (Moretti is about 940 degrees F) and the length of time depends on the thickest part of the bead (a typical time might be 15 minutes. Longer won't hurt). In other words the larger the bead the longer the annealing time. Beads can be cooled, then at any time later, put back into a cold kiln and brought up to temperature for annealing, or the annealing can be done immediately by putting the bead, still on the mandrel, directly into a hot kiln right from the torch flame. A HotGlass kiln is specially designed so a bead can be safely put directly into a hot kiln.



There are four popular methods of cooling glass beads.

Cooling the bead by slowly removing it from the torch flame.
This is called flame annealing. Many artists use this method of flame annealing even if they are using a kiln.
This may keep smaller sized beads from thermal shocking
This method can do some annealing for any sized bead if done properly.

Placing your beads between two layers of fiber blanket. See more about this.
This method may keep smaller beads from thermal shocking.
This method does nothing to anneal your glass bead.

Bury your bead deep in a hot crock pot filled with hot vermiculite.
This method may keep smaller beads from thermal shocking.
This method does nothing to anneal your glass bead.

Place your bead in a heated kiln.
Using a kiln will keep any sized bead from thermal shocking.
Using a kiln will anneal your glass bead if kept at the correct temperature for a sufficient period of time.



How is a Lampworking Kiln different from a Ceramic Kiln?

A ceramic kiln would work as a bead kiln. But a Bead Kiln has many desirable and safe features. Remember, beads are put into a kiln while it is on and hot!

Safety - if you put a bead, still on the mandrel, into a ceramic kiln and you accidentally touched one of the exposed element wires, you will become electrocuted! Our Bead Kilns protect you so you will not become shocked!

Heat - Yes! when a kiln is used for glass beadmaking, it is kept at about 1000 degrees F. When you open a ceramic kiln at 1000 degrees to put in a bead, you will be hit with a lot of heat. Our HotGlass kilns have a special opening on the side, which allows you to easily and safely insert your beads comfortably. Simply lift up the loose cloth door and place the mandrel into the bead rack.
