It's Stained! Not Stain...Arrgghh

Ok, I am better now. I would like to take this opportunity to correct about 1/3 of the worlds population on the correct pronunciation of the term "Stained Glass". (ok, maybe not 1/3 but it sounds good to me). 

So often I hear and see people talking about Stained Glass and using the term Stain Glass. Stain, according to Wikipedia:  A stain is a permanent discoloration that can be clearly distinguished from the surface, material, or medium it is found upon. 

If you have a stain on the glass then you have a problem! I don't know how the phrase "stained glass" came to be but I do know the glass is in no way stained. Confused? Wait until I explain what "Glass" is.... stay tuned!
