Coefficient of expansion

COE for short. Important, because as glass cools it might cool at a different rate to the bit it is stuck to and so one bit will crack. But does it require the tedium of a 2 hour 40 mins lecture? Might do -- but, moi, I'm skipping it tomorrow in favour of experimenting. I can read about the technics in a book, but I can only try out a kiln on my booked day -- one a fortnight, and mine's tomorrow.

I'm trying out ways of embellishing this chandelier with glass to interplay with the light. I bought it in a junk shop and am converting it back to candles.
