This is for you glaze experts and any lurkers who also work with glass.
Anyone know if it possible to find out the COE rating of a cone 06 gloss glaze and also of a cone 5 gloss glaze? And if so where and how?

I am trying to figure out if there is someway I can adjust a glaze so it would have more compatibility when fusing to glass with a COE 90 or 96.

Hi Barbara,

In chapter 5 in our book - page 81 you will find a high expansion glaze -
it will be the one closest to your glass.

Do a line blend between that one and the one on page 79.

If it takes a higher expansion glaze to work I can design one for you.
