help with fusing problem

Help, please! I don’t understand what is going on with the glass. I made a sheet glass / frit piece, put it in a full fuse, cut it up into tiny pieces, ground them to shape and refused on a full fuse. Although they shaped beautifully the grind marks remained on all of them. You cannot feel the grind marks, just see them. This happened before at a glass class and the instructor just shrugged and said it was probably the glass. I use only 90. This is my glass and hers was a different source so clearly it is me. All 40 pairs the I touched with the grinder show the marks. I have no idea where I am screwing up. The larger items are not showing the grind marks. Please please help. Thanks!October 31, 2013 at 6:45 pm #13088wordanaParticipant
Here are multiple suggestions:
Could be that you are not cleaning the edges well enough after grinding. After grinding and before cleaning, put them in a bucket of water to keep the grinder scum from drying on the cabs, and then scrub the edges really well when cleaning.
Also, make sure you are using a fine grinding bit.
If you are firing on “thinfire” try kilnwash. Many people report devit when using ThinFire when using Bullesys glass (oh! the irony! ). Personally, I have rarely seen this problem, but I use Sys96.
If you are cutting ThinFire for each cab, but you have a fairly large ThinFire “margin”, the TF can curl up during firing and stick to the edges.

You are brilliant!!! I followed your instructions, ground away the distortions and scrubbed them really clean. It is about 90% gone. I am going to order a finer grind bit as soon as I see a sale. Thank you so much!!!November 4, 2013 at 7:09 pm #13090
