EPK fired bar (top) vs Grolleg at cone 10R. Why shrinking more?


Wednesday 27th July 2016

EPK has a much higher fired shrinkage. This is counter intuitive because Grolleg is known to produce more vitrified porcelains. It also appears whiter yet in a porcelain body the Grolleg will produce a much whiter fired product. This means that to compare porcelains we need to see them "playing on the team", in a recipe working with other materials, to see their the properties they really contribute.
