Stained Glass in DoubleglazingO 

You have to buy the dvd which is relatively inexpensive but gives more detail.

I agree, I'd love to know what materials are being used in this prject.

the lead does'nt oxodize when sealed the warm edge spacer absorbs the moisture in the sealed unit preventing oxiziation

Instead of music, maybe some step-by-step info! :)

The information on what and where to get the product would be helpful! The music is terrible!
