Whoa-wait!!!

Is it clear celluloid?!

DON'T heat it!!! (http://www.oregonknifeclub.org/celluloid.html)

Celluloid, especially the clear 'stuff' is highly suseptible to degradation. Heating it will only make it more unstable. I've had a set degrade on me and take out a few razors along the way.

Post a picture of the scales if you can....
