GTF-MD-16 Series (1600°C)—Horizontal Gradient Furnace

The Orton GTF-MD-16 is a specially designed horizontal tube furnaces with controlled, reproducible, linear thermal gradients of approximately 10-12°C per inch.  This gradient allows you to study the effects of temperature on properties at various temperatures. As a liquidus furnace it is useful for determining the maximum temperature at which crystallization will form in a glass, and the minimum temperature at which a glass can be held for extended periods of time without crystal formation and growth.
