1″x1.5″, glass

I’ve been doing some glass fusing with two classes at the High School.  One of the key concepts in fusing is compatibility.  All of the glass that’s fused into one piece has to have the same coefficient of expansion (COE) so that it doesn’t crack apart as it cools.  Glass that’s compatible expands and contracts at the same rate, heating and cooling in synch.  I was thinking today about compatibility of people, and how it’s almost the same.  Friendships work best when everyone likes the same balance of activity and down time, the same amount of dancing and napping.  Of course, people can see past incompatibility and make friendships work anyway, but glass isn’t as forgiving. This pendant is made of stringers of compatible glass (all 90 COE for anyone who’s interested).
