Celestite Crystalline Glaze
Recipe
Notes
From Crystal Glazes Book 2 by Fara Shimbo, page 63. Maturing Cone: 9-10 Crystal number: Plenty! Can rapidly fill a tile. Rate Of Growth: 1-1.5 cm diameter per hour, tiles or vessels. Crystal Color: Pale aquamarine, reminiscent of Michigan Celestite crystals. Crystal Shape: Cigar-shaped normally; not much variation with temperature. Ground Color: Colorless transparent on both tiles and vessels. Crazing: Minimal on vessels; more on tiles. Color Response: Works well with all colors. Brings out red in manganese; copper comes out a true cyan. Iron and Vanadium often pale. Seeding properties: Okay. More information in Crystal Glazes book 1 page 138 and book 2 on page 63. Much more background information in other sections of the books.
