I have several pounds of some "classic" materials that are no longer available, at least in these vintages.
The supply dates from the 90's, 80's and earlier. There's at least 25 pounds of each.
Cornwall Stone, Spodumene (Foote), Clinchfield Spar ( a high Pot Spar from 1960!) and Avery Kaolin.
I've been hanging on to them, thinking about the best way to use them up. Then, I thought... why not
ask some other long time potters! Any suggestions of classic recipes that used to work that didn't survive
one of these material's changes? Complimentary tea bowl with your glaze as a thank you for your suggestion.
