Special effects glaze.

I used the recipes found in Linda Bloomfield's Special Effects Glazes book.

I had previously used a Marilee Lava glaze with mixed results, so chose Matt Katz Zinc crawl base and Linda Bloomfield's Magnesium Carbonate based Lichen Glaze, both reacted really well with the black clay.

I was pleased with the results of testing these recipes and decided that the next steps would be to add the lichen glaze to a smaller sculpture and to add further stains and colours to a fresh batch of this glaze and apply to a white clay body as the 10g of orange stain I had added to a separate batch disappeared on this test. Although I felt this was more likely to be due to the high manganese content of the black clay as it is notorious for just swallowing up colour, I needed to test further on other clay bodies to see how colour responded in the lichen glaze recipe.
