AMACO CO-6 Supernova crystalline glaze

AMACO Cosmos Supernova is a creamy white, translucent crystalline glaze. Its frosted crystals evoke winter mornings and windows traced with delicate frost.

AMACO Cosmos Supernova is a highly fluid crystalline glaze with a creamy white, translucent base. After firing, it develops a glossy, opalescent surface with crystals reminiscent of frost on glass, while thinner areas break slightly creamier. AMACO recommends firing it at the lower end of the 1200-1240°C range. It can also be layered over AMACO Velvet Underglazes, allowing colored effects to remain visible beneath the opalescent surface.

AMACO Cosmos

AMACO Cosmos is a range of highly fluid crystalline glazes for firing between 1200 and 1240°C. In a standard firing, they develop opalescent microcrystalline surfaces with depth, movement, and pronounced variation. No special firing schedule is required. Controlled cooling can, however, encourage more pronounced crystal development.

Brush the glazes onto clean, dry bisque-fired ware in 3-4 generous coats. AMACO recommends four coats for a fuller crystalline effect. These glazes are highly fluid, so stop application approximately 1.5 cm above the foot or use a drip tray to catch runs. To support off-gassing and reduce pinholing and blistering, leave the inside or back of the form unglazed. The final result depends on application thickness, clay body, firing temperature, and cooling cycle, so we recommend firing a test tile.

The glazes are labeled food safe. However, because of the limited durability of the fired surface, AMACO does not recommend them for food-contact surfaces. They are best suited to decorative ceramics, sculpture, tiles, and ceramic jewelry.

Amaco Cosmos CO-06 Supernova Crystalline Glaze

• Creates a creamy white, translucent, glossy surface with opalescent crystals reminiscent of frost.
• Develops its fullest effect at the lower end of the recommended 1200-1240°C firing range.
• It can be layered over AMACO Velvet Underglazes to create colored effects visible beneath the opalescent surface.
• The crystalline effect develops in a standard firing. Controlled cooling can encourage more pronounced crystal development.
• Apply 3-4 generous coats to bisque-fired ware. AMACO recommends four coats for a fuller effect.
• The glaze is highly fluid - leave approximately 1.5 cm unglazed above the foot and protect the kiln shelf from runs.
• Best suited to decorative ceramics, sculpture, tiles, and ceramic jewelry.
• Labeled food safe, but AMACO does not recommend it for food-contact surfaces because of the limited durability of the fired surface.
