I would think adding alumina till it worked would be the answer - I use 2
spoon fulls (teaspn) to a cup of wax. Works on porcelain which is the
hardest to keep apart.
Big thing is to keep it well stirred - alumina wants to sink to the bottom.
DON'T get it close to the glaze - just on the bottom of the gallery or the
foot - use regular wax first and then just a touch of the mixture where
it's needed. If the glaze gets a bit over the wax (as it usually does) the
glaze will not attach to the clay sometimes. This leaves a cutting edge
where the glaze meets the exposed clay.

It's been a long while since I made up a solution of Alumina Hydrate & Wax
Resist to brush on the lids and galleries of my lidded vessels to keep them
from sticking together during firing. In fact, it's been ages since I even
made any high fired lidded forms since the last decade or so I've been mostly
doing raku vessels.
I was wondering if anyone knew offhand how much Alumina Hydrate I should add
to Wax Resist for keeping the lids from sticking together during the glaze
firing? What is a good ratio, or does it even matter much? A pinch of Al.
Hydrate to an ounce of Wax Resist, or ??? (i.e. - 1 Tbsp. for ea. 1/4 cup,
etc., etc.)
TIA...

I use 1 teas. to 1/2 cup of wax resist. Susan

Hi,
I was told by Tom Coleman at a workshop last spring to use 1TBSP of alumina
hydrate to 1/2 c. was resist.
Hope this helps.

Dear Kenneth
I found it a better Idea to wax and paint the alumina on separately I just
mix as thick a coat alumina and paraffin as possible for painting and just
paint the gallery before. If I get the alumna too thick it can drop into the
pot but that would happen with the wax as well.
