It runs 24/7/365 and stays between 2000 and 2400 degrees Fahrenheit. The furnace consists of high temp ceramic castable and it takes about 6 days to reach the correct temperature, so if it ever goes out, we’re out of commission for a few weeks.Kiln-fired glass, or warm glass as it is also called, is typically done in an electric kiln at temperatures lower than ceramic temperatures. 1300-1500 degrees F is typical. For reference, Cone 04 is about 1900 degrees F and Cone 10 is about 2350.A torch used quite extensively in the industry is the National Handtorch Type 3A Blowpipe shown here. This relatively inexpensive torch, with tip sizes #2, 3, 4,and 5 will cover most of your needs. Surface-mix torches and burners are used most frequently when large areas of glass need to be worked.

How hot is the glass making?
The transformation of raw materials into glass takes place at around 1,320 °C (2,400 °F); the glass emits enough heat to appear almost white hot. The glass is then left to “fine out” (allowing the bubbles to rise out of the mass), and then the working temperature is reduced in the furnace to around 1,090 °C (2,000 °F).

How hot is an Annealer?
To anneal glass, it is necessary to heat it to its annealing temperature, at which its viscosity, η, drops to 1013 Poise (1013 dyne-second/cm²). For most kinds of glass, this annealing temperature is in the range of 454–482 °C (850–900 °F), and is the so-called stress-relief point or annealing point of the glass.

Glass annealing ovens or furnaces are used by glassblowers to eliminate stresses created in glassware during the glassblowing process.
Which is hotter cone 05 or 06?
That is not to be ignored!
Cone 6 is about 400 degrees hotter than cone 06! As you can see from the pyrometric chart (above), the “0” serves as a negative sign. Therefore cone 05 is cooler than cone 04 whereas cone 5 is hotter than cone 4. For the most reliable results, it is best to match your clay with your glazes.
