It is often argued that a clay has only to be fired to the listed temperature, to be considered “well fired” or “safe”.
We at Ceramic Materials Workshop couldn’t agree less.
We need to understand what we should be actually looking for, when we are looking at the numbers for our clay bodies.
There is a scandal in ceramics.
The firing temperatures we are often told at “good” in fact are not. There is a standard that we should be expecting in commercial clays. Many clay bodies, especially at cone 6 do not meet that standard.
So let’s talk about vitrification and why it is important!
