alright this topic seems to have answered a question I had and raised a few more.
I have an 11x14 contact frame, Century made and it needs glass. Based on this discussion I should get antiglare and thicker than 2mm. For this contact frame, how thick should my glass be? I understand that some of you are using super thick glass which has the weight enough and eventually I will probably go that route but I have a gadget and I want to use it! ;-)
