This is my first official time at making a glaze from scratch. Its a simple white glaze from a Lucie Rie recipe, fired to ^6 oxidation
I associate Lucie Rie with a time long before ^6 became popular. Are you sure that this glaze is intended for ^6?
Had a quick look and found this posting, suggesting a significantly higher firing temperature.
Also note the possibility of crawling when used on bisc.
Miri, I share your love for Lucie Rie's work. I have one recipe (copied long ago from a UK ceramics book but never used) attributed to her. Here is the text (verbatim with commentary) from the book:
Lucie Rie's White (oxidized, 1,250°C)
58 soda feldspar
14 china clay
10 zinc oxide
10 tin oxide
This glaze is the famous glossy white glaze used on Lucie Rie's tableware, often stained brown with manganese and copper carbonate on the rims. It can be tried with less tin - 5 or even 2 percent - but is expensive to make, and inclined to crawl when used on biscuit ware, perhaps because of the high zinc content. Lucie Rie's pots, of course, are once fired, which avoids this problem.
