I have used liquid laundry starch in my glazes for a number of years.
It harden the dried surface and nearly eliminates glaze 'powdering' on
kiln shelves. Also makes brush decoration much easier. Now I can't
locate the liquid starch in any stores in may city. It seems starch
is not used in our relaxed clothing. Any suggestions?
