Mornin' John,
I found a recipe in the archives for a glaze that uses
your list of ingredients. Here is the link.

I've read about it before and wanted to mix up a test but never did.
Would love to hear how it works for you.

Who won't turn on the news again.

Hi John,
The recipe amounts divided by 10 to add up to 99.8
would add by percent

4 Co. Carb.
30 Rutile

I am sure this is a typo, and 3 Rutile is correct.

I will try it as well so we can compare tests.

regards from Alisa back in Denmark
after a lovely warm holiday on Tenerife.
Spain is full of colorful ceramic mosaics
up and down lamp poles, as protection around
trees, park benches, etc.
