Description
G-200EU Potassium Feldspar
This is the only potassium feldspar we sell now. It is a good substitute for Custer which is no longer available. It may not be a direct 1:1 sub in your recipes, so YOU MUST TEST IT FIRST. We have found it melts sooner than Custer, so you may need to adjust the quantity in your recipes.
It is much cleaner than Custer, so white clay bodies may have a noticeable improvement in whiteness if you move from Custer to G200EU.
****SOLD in 5 lb bags and 55 lb sacks only. This is made in Spain so the bulk bags are 55 lbs not 50 lbs
