A couple have e-mailed me off list to see what I'm up to with the pearl ash.
Here's what I'm up to.
I have been using a standard ash glaze recipe called 221 from Leach's book.
2 ash, 2 feldspar, l ball clay. this year at home we started burning some
soft maple, some ash, some chinese elm( Not really great hardwoods). My ash
glaze although good on small pieces is like steel wool on the larger pieces.
i lost 4- 30 lb platters for a show that just about broke my heart. So my
plan is to mix up an ash substitute from Phil Rogers book. I will mix up
the below mentioned recipes, add water, put thru a 80 mesh screen and dry in
a bisque bowl over the kiln. Put the dry ingredients in a bucket in my glaze
room and whenever a recipe calls for ash, I will take it from my ash
substitute bucket. this should offer some control over the outcome.
I'm listing two recipes for beech ash here- one for trunk wood an in this
business called pottery, I'm chickening out a bit.

cheers,
