Kiln Wash

Kiln Wash A high-melting powder applied to kiln shelves to prevent ware from sticking to the shelf during firing. It is also used as a parting agent for to keep elements of fired ware from sticking to each other. Details A refractory powder that can be mixed with water (and gum solution) and painted on kiln shelves to prevent ware and accidental glaze drips from sticking.

Oxide ceramic fibers via dry spinning process—From lab …

Pure alumina and silica without seeding (round dots) require higher temperature for mullite formation (1250‐1300 C), while seeded alumina (triangles) results in mullite formation at 1100‐1250 C. Seeding can reduce mullite formation temperature. 28 In consequence, smaller grain size of mullite could be expected due to the lower temperature required for crystallization.
