I use both C10 and C5 B-Mix because I have glazes in both ranges that I
like, and I don't fire at just one temp. As careful as I am about marking
the bags when I open a box of clay, I've accidentally applied C10 handles
to some C5 mugs.
Maybe you can guess the results...
If you put these in the microwave full of liquid, the handles (not being
fired to maturity) get hot enough to burn.
Not something I would do on purpose!
