I inherited a lot of glazes from a retiring potter and they have been sitting for well over a year, maybe more.
I will be doing some glaze testing next week, to see which ones are still good and which ones need to be tossed.
I have been reading about the processes of flocculation and deflocculation.
Could someone confirm/clarify for me:
If the glaze is too runny, you flocculate - using epsom salt or vinegar
If the glaze is too thick, you deflocculate - using a product called Darvan
Is this correct?
Also, with old glazes that have sat for over a year, and thickened up.... would you toss them or attempt to make them good again?
Thanks for being so respectful and going easy on me with all the newbie questions. This website has been such a fabulous resource!
