Chantay Posted March 5, 2014 Report Share Posted March 5, 2014 I bought a grinder last week and have been tackling my shelves. I am thankful to have extras and it not be critical to use the same ones each firing. I always try and chisel and chip first. I use all safety equipment. I have a 'basic' 4 1/2 inch grinder. I have heard of getting diamond grinding heads. Today I was grinding down a patch. It got to the point that the glaze drip was smooth and slick and level with the shelf surface. My question is: do I continue grinding down into the shelf to remove the rest of the glaze or leave the remainder of the glaze as is and put kiln wash over it. Which doesn't sound right but I can't figure out how to get the glaze off without taking a big chunk out of the shelf. sorry for the rambling, tired. As always I greatly appreciate the help offered here. Link to comment Share on other sites More sharing options...
jrgpots Posted March 5, 2014 Report Share Posted March 5, 2014 I grind it all off. But I am a bit OCD. good luck, Jed Link to comment Share on other sites More sharing options...
Colby Charpentier Posted March 5, 2014 Report Share Posted March 5, 2014 Yeah, it's good practice to grind down to remove all material, as continuing to fire a shelf with glaze material on it will continue to cause issues with the glaze "grabbing" work, and eating further through the shelf...

Marcia Selsor Posted March 5, 2014 Report Share Posted March 5, 2014 the glaze will continue to melt in the firings, so it is better the get all of it off. Marcia Link to comment Share on other sites More sharing options...

Mark C. Posted March 5, 2014 Report Share Posted March 5, 2014 Once you grind it all to clean good shelve you can fill the hole with wash before washing the whole shelve. There was a thread abou fill material options last year If I recall. Mark Link to comment Share on other sites More sharing options...
