Cerafirm replaces your branded porcelain fluid to change the handling characteristics of the porcelain during the build-up. It makes for easier layering with different consistancies and allows complex internal structures to be produced using over-layering. Re-positioning of already placed ceramics becomes easy as does creating structures and texture even before firing. Being Glycol-free it does not affect the colour and minimises shrinkage of fired porcelain. You can vary the viscosity of the ceramic using the Cerafirm 'Add'.
