 |
|
Glass is termed "European glass" and is thinner than our single strength
window glass and more importantly, is ground on one side. How expensive
is this glass in GB and Europe? I was looking for 2 pieces 8.5"x 11.5".

Yep, that is where I found info on how to grind down our own glass, but
was wondering how expensive is the real thing. The procedure set forth
in the link could have high FOF (Failed Operation Factor). |

Bill, I've never heard of "European glass" over here. All normal window glass here these days has to be at least 4mm thick for safety, but I think it might still be possible to buy 3mm "agricultural glass", used in greenhouses. The only glass 2mm thick I know about is "picture" glass, maybe you could get a couple of cheap photo or picture frames?

Peter, that sounds like a good idea! I wonder if some picture glass is
ground on one side for antiglare... I'm using these for negative/positive holders for scanning. I'm going to call around to different glass places,
and if they don't have any glass ground on one side, will try grinding my own from single strength window glass. |

In that case the thickness isn't critical is it? I thought you meant for a camera. You can acid etch or sandblast glass too for almost the same effect. And frosted glass shopfronts these days are done with applied film on plain glass (like 3M Magictape). So there's lots of ways to do it!

You can also buy frosting spray - don't know how well it works...
It might be worth trying your local picture framers to see what they've got.

Found a picture frame company that stocks non-glare glass and can cut
it any dimension from the 11x14" blank. Will see what shakes. |

Peter, your idea of picture frame glass and my idea of non-glare glass I
think has paid off! The non-glare stuff is ground on one side, the other side
is shiny. I just had a piece cut that will fit the bottom of the scanner (less
almost a half inch at the top) for $16.20 tax included. This is about 2mm
thick, brought my calipers home so will verify. More to follow...

Here's a quick and dirty scan to see if it works. For masking I used heavy
construction paper, flat black, comes 50 sheets to a pack for $1.99 at
Staples, 9x12":
Some dust, didn't clean up all of it, and probably from using a strip of
emory cloth to dull the glass edges. Pic is a little over-exposed, will try
some others. How is sharpness in this?
Bill

Looks good on my monitor, but I am getting older (and not wearing my glasses) 
Are you just laying the strips on the scanner, without a holder, and using the glass to flatten them?
