How can salt (NaCl) ever possibly form sodium silicate in the process of salt glazing (pottery)? isn’t the bond in salt way to strong for something like that to happen?
In: 2
In salt glazing, it’s not the salt itself but the extreme heat of pottery kilns that causes a reaction. The heat breaks down the salt (NaCl), releasing sodium (Na) and chlorine (Cl). The sodium then reacts with silicates in the pottery to form sodium silicate, creating a glassy glaze. So, it’s not about the strength of the salt bond, but the high temperature that makes this happen.
