Application Recommendations

  1. Engobes: Apply 2-3 coats to a soft fired (cone 04) or fully fired (cone 10) stoneware or porcelain body (Note: the clay body must be capable of withstanding a cone 10 firing).
  2. Seeding Media: Apply single dots or a wash (4 parts water to 1 part Seeding Media) on the Engobe-covered surface.
  3. Crystalline Clear: Apply 3 coats over the Engobe and Seeding Media applications. This glaze MOVES and will require a basin to catch glaze drips. Application tip: Apply the first coat to the entire piece; stagger subsequent coats higher up on the ceramic ware to lessen the flow of the clear glaze from running off the ware.
  4. Enter the firing program (below) into your programmable kiln controller and start the program.

a. Ramp 1: 9999 (take the kiln up to temperature as fast as possible) to 2300°F (1260°C)
b. Hold 1: 0.00
c. Ramp 2: 9999 to 2012°F (1100°C)
d. Hold 2: 6.00 hrs

Notes: While the recommended hold time is 6 hours crystals may be formed in as little as 3 hours.(Longer hold times will produce larger crystals, shorter hold times will produce smaller crystal growth). Test to verify compatibility of decorating colors other than Mayco Engobes as Crystalline Clear can be aggressive towards underlying colors. Thicker applications of crystalline Clear tend to produce larger crystals. Varying the thickness of the Engobes and Seeding Media, as well as the Crystalline Clear can produce vastly different and exciting results. Blending different Mayco Engobe can produce unique colors.
