The clay-based domestic wares, art objects and building products are familiar to us all, but pottery is just one part of the ceramic world.
What is crawling in pottery?
Crawling is where the molten glaze withdraws into ‘islands’ leaving bare clay patches. The problem is by far most prevalent where bisque-applied glazes contain excessive plastic clay content or are applied thickly or in multiple layers.
What makes ceramic glaze shiny?
If you want your matte glaze to be satin, or only slightly glossy, just add a small amount of Silica. Typically a SiO2:Al2O3 ratio between 5 and 6 will give you a satin glaze. If it’s too matte, add some Silica. If it’s too glossy, remove some Silica.

Why is ceramic so hard?
The atoms in ceramic materials are held together by a chemical bond. The bonding of atoms together is much stronger in covalent and ionic bonding than in metallic. That is why, generally speaking, metals are ductile and ceramics are brittle.
Is ceramic waterproof?
