One of the quickest and easiest way to test compatibility is to take a piece of your dichro or any glass in question.....and over lap it on a rod of glass you know the COE for. I try to over lap about an inch. Melt them together and pull out into a straight stringer. Set aside. If the glasses are compatible the stringer will stay straight...if they are not - the stringer will bend into a curve. This will show the the two glasses have a different contraction rate in cooling. It is not the most scientific method but an old time quick test
Hope that helps
