Parmcat Posted June 16 Report Share Posted June 16 These 4 all came together. The larger ones are about .74, and the small one is .54. Under black light, they have a glowing mark. Is there a reason? What do I have? 1 Link to comment Share on other sites More sharing options...
Alan Posted June 16 Report Share Posted June 16 It could be anything...some scrap. UV reaction is not a big thing. 1 Link to comment Share on other sites More sharing options...
Ric Posted June 16 Report Share Posted June 16 It's not often meaningful. If you didn't wash them it could just be a surface stain from who knows what. 1 Link to comment Share on other sites More sharing options...
akroorka Posted June 17 Report Share Posted June 17 This is pretty weird. I have never put clays under UV light for whatever reason. I will start today. Great tip here and I do not have any explaination for it. Nice job! Marble--On!! Link to comment Share on other sites More sharing options...
