We always got the glass from a glass shop. Be sure they sand the edges to prevent injury.

The glass provides good contact between the mesh and the positive. It should be larger than the image so you don't have to touch up any lines caused by the edge.

 

yeah basically the glass just put weight on the transparency so it doesn't try to lift from the screen. the piece i use is out of an garage door... it is actually wide than the screens which isnt great but it works good

 

You can epoxy glue a masons trowel to he glass so you have a handle to pick it up. Use 3/8 - 1/4 inch glass and tempered if possible so if it breaks, you don't get scarred. I would also get a black tee and put it smooth and flat between the glass and screen to keep light fraction down. Low watt light sources with long burn times can " creep " around opaque areas and choke your design if it reflects off the glass. I used to put about 10 pounds ( dumbbell ) on the glass to make sure I had no ghosting also.

 

I just got mine at home depot, cut to size (smaller then the frame size, dont want it resting on the frame, just the screen). Nothing fancy but works just fine for me when I am using my 500w halogen set up for hybrid diazo emulsion.

 

Got mine at Michael's in the custom picture frame department. They'll cut it to size for you.

 

Thanks for the responses everyone!

Last time I went to Michaels I was asking for tempered glass but they didnt have any, would it be alright if it's just a normal piece of glass?

 

I just use normal glass. Make sure it doesn't have and archival coating or uv coating. Some frame shops put that in their frames. Just be careful with your glass. If you bust it just be careful cleaning it up. Store it someplace out of the way. Youre an adult you can handle a piece of glass lol.

 

Got mine from a Glass shop. Also Non UV, sanded edges which they'll do, non green I believe it's called.

1/4" and big enough so the edges don't cause lines on the screen. The cost is about $85.00. I bartered with the shop so I only paid for the mugs I gave them.
