kiln wash recipe

I am interested in the recipe for the do-it-yourself kiln wash which will not flake of in the first high firing. I would love to hear what do you potters out there use. thanks in advance, Andrea


The traditional was 50 % Flint, and 50% Kaolin by weight. Then Ron Roy proposed a flint free version that doesn't get sticky as fast:

80 % Alumina Hydrate 20% ball clay. That's what I use now, applied thinly. Brad Sondahl A

reply to me directly, don't forget to take out the "garbage" from myaddress.

If I use kiln wash, and I usually don't unless I am testing new glazes, I use a combination of half kaolin and half alumina hydrate. I don't like to put silica in a kiln wash because I find that B-Mix can fuse to anything with silica in it. (Cone 6 reduction).

Used fairly thinly for electric firing, medium for reduction, pretty thick in the wood/salt kiln.

Very reliable

Steve,

I've noticed in directions, not to wash to edge. I've never understood the what for of this.

You bring it up with the "Sponge off shelf edges."

What is the reason for not completely covering the shelf?

As you handle the shelves you may rub off and drop some of the wash on the lower pieces. It may flake off and fall down on a lower piece during firing and ruin the finish. Good advice to keep the edges clean. regards, Tony

Stops bits/flakes fall onto anything below by cleaning off any splurges
