Babs Posted December 31, 2013 Report Share Posted December 31, 2013 What is the reason for wiping ware with diluted vinegar prior to majolica glazing/ Is this practice recommended for all glazes? Link to comment Share on other sites More sharing options...
bciskepottery Posted January 1, 2014 Report Share Posted January 1, 2014 Diluted vinegar can remove scumming that is sometimes found on bisqueware -- scumming is the result of soluble salts on the surface. My guess is removing with vinegar on majolica ware is important because many fire earthenware one cone higher for bisque than for glazing and the scumming would not otherwise burn out. Probably doesn't hurt other firing temperatures. Link to comment Share on other sites More sharing options...
Marcia Selsor Posted January 1, 2014 Report Share Posted January 1, 2014 Also for majolica,,surface blemished should be sanded and washed. Blemishes also cause crawling. Marcia Link to comment Share on other sites More sharing options...
