Glass Crystallization Test Furnace
The GXT glass crystallization test furnace uses the gradient furnace method to determine the crystallization temperature range, upper and lower limits, and degree of crystallization in glass. It is used to test glass, gemstones, and other non-metallic materials in factory, school, and research laboratories.

Product Description
The GXT uses the gradient furnace method with a temperature gradient of 1000–1,600 °C. Crystallization is the spontaneous formation of crystals by glass under certain conditions; the test determines the crystallization temperature range, its upper and lower limits, and the degree of crystallization.
These results can be used when establishing melting, forming, and thermal-processing conditions. The furnace is used for testing the crystallization properties of glass and other nonmetallic materials.
