Thanks for the advice and the link -- I have a quart of Aftosa on the way. Meanwhile, if anyone has any other recommendations, I'd love to get a few options shipped here before winter sets in and I'm stuck with whatever I have (in case the Aftosa isn't just quite so...). Thanks!

So I bought a quart of a beige colored wax resist about 10 years ago from my local supplier (Portland Pottery in Braintree, Massachusetts); I am just about out (didn't use it for years but it has recently become indispensable...) and of course they no longer sell it and nobody there can tell me what it was (they sold it an unmarked plastic bottle). I am pretty sure that it is not water soluble, like most wax resists seem to be (at least, I can't wash it off my brushes); I apply it over glazes (to keep the next glaze from sticking), and I like that it is not runny -- it doesn't drip (I fling it on with a brush...). So: Anybody have a guess as to what it might be? If not, a suggestion for a good replacement? Many thanks.
