Use of mini-jars
When we realize samples for the research for new glazes we are confronted with the problem of the grinding in small quantity. If we put 50gr of materials to crush in one porcelain jar of 5 liters we do not find them. A solution is to pass in the cylindrical flasks in polyethylene of a half-liter . I thus made a do-it-yourself put on the potters whell to make turn these flasks.
