Can I use salt instead of Epsom?

While both salt and Epsom salt can be used in ceramics, they serve different purposes and produce distinct effects on glaze and clay surfaces.

Salt in Ceramics:

Salt is often used in a technique called salt glazing, where salt vapor is introduced into the kiln during firing. This process creates a characteristic orange-peel texture and a glossy finish on the pottery surface.

Epsom Salt in Ceramics:

Epsom salt is primarily used to achieve specific surface effects, such as fine crystalline patterns and matte finishes. It is added to glaze recipes to create visual interest and texture.

Substitution Considerations:

While you can’t directly substitute salt for Epsom salt in glaze recipes, you can explore the use of salt in salt glazing techniques to achieve unique surface effects.

Ultimately, the choice between using salt or Epsom salt depends on the desired outcome and the specific technique you wish to employ in your ceramic work.
