I need your advise.
I achieved a beautiful glaze, a very beautiful glaze.
Not for food!
On the back of the last plate I made I even wrote: "Not for food" with
an engob!
Every "mistake" was done deliberately! Again, to "beat" Mark& Dave in my
own oxidation field!

The price is that it is a "foodless" ware!
I need to know, besides all the "bad" things I tell you is there any
problem to use it for decorative wares? Will it shiver or any other
I want to add here!
I am not sure exactly why, but the expansion does not take much place in
my glazes, I do watch it, but I hardly have any problem.
Of course this one is defiantly not a regular glaze: It is glossy runny.
I use the ash analysis of Herbert Sanders
