How do you make porcelain stronger?
Clay: Imparts plasticity and drying hardness to the wet materials and transforms into a mesh of crystals during firing (which gives porcelain its strength). Feldspar and Nepheline Syenite: The melting of the feldspar fills the voids between the silica and clay particles and cements them into a strong mass.
Can cold porcelain be baked?
Natural Cold Porcelain Clay is a perfect substitute for toxic polymer clay and allows for even finer detail and ease of sculpting. It’s also incredibly inexpensive and super simple to make. The clay is air-dried so no need for baking and it dries to a light weight, luminous, stone-like texture.
Why did my clay crack?
In general, cracks result from stresses in the clay. There is always some stress in clay because of the fact that it shrinks as it dries and when it is fired, and it also expands and contracts during firing. Sometimes the stress is too much for the clay to handle and it cracks.
