This fine white New Zealand porcelain body has to be plasticized using an expensive white bentonite (VeeGum). In this test mix, the percentage of VeeGum was slightly low (3.25%). Although it is very plastic and throws well on the potters wheel, the tendency to split at the rim is evident on this dried mug. Only 0.5% more Veegum is needed to solve this issue. The percentage is critical, enough to eliminate this issue but not too much or the drying shrinkage will be excessive.
