One of the discussions on the bullseye forum that a few of us are having is around where some discolouration – grey line – is appearing at the edge of some of the glass after a full fuse.
So I have put the photos here for viewing as part of the discussion.
If you look carefully at the red plate on my previous blog at the top of the virtical where the red meets the yellow. You will see a grey line where I joined two clear pieces to form the top layer.
Harder to show is that there is often a grey line around the edge of a piece. Various recommendatsions have been made so I did the following test.
Two pieces 3 by.5 inch. 2 layers, thin clear and colour base. both items had all its sides ground, one set was immediatelly put in to water bath. From the photos I cannot tell which was which as both have grey lines.
