Hi, I am playing a bit with a trick I read quite some time ago on Newsnet on making your home-made groundglass with parafilm:=20 see: http://groups.google.com/groups?q=3Dparafilm+ground+glass&hl=3Dnl&lr=3D&s= elm=3D6 e62ul%24hlp%242%40news.ececs.uc.edu&rnum=3D1 It seems to be a neat way of making a groundglass, the first tries look very promising (provided that you can lay your hands on parafilm..;-)..). To realy finish this project in a nice way I would like to have grid lines on the glass. I could draw them carefully, or make an overlay of a grid printed/copied on a sheet of transparant material. But I was wondering if there is a method of engraving the glass with tiny straight scratches, and then rubbing in say India ink? thanks, Best, Cor ============================================================================================================= To unsubscribe from this list, go to www.freelists.org and logon to your account (the same e-mail address and password you set-up when you subscribed,) and unsubscribe from there.
