Painter1 Posted July 8, 2023 Report Share Posted July 8, 2023 Quite a long time ago I saw a post/pictures/video of a griddle filled with clay-based foundry sand formed around several borosilicate cups. Purpose being to keep several small quantities of different colors hot enough to remain usable for a reasonable period. IMS, it may have been from Frank. I bought the forming clay/sand https://www.amazon.com/Teton-Bond-Petrobond-Fine-Mesh-Foundry-Casting/dp/B07J19XZYD/ref=sr_1_1?m=A2F0NR23SCAQGR&qid=1688842728&refinements=p_4%3ATeton%2BSupply%2BCo.&s=merchant-items&sr=1-1&th=1 but not sure how to make it so that the cup shapes hold in the griddle with repeated use. Do I just form it around the cups and turn on the griddle for while? How long? How hot? Do the cups need to be treated with some sort of release agent? I’m not using all the (expensive) soft plastic injection/production equipment anymore as my interest has turned to customized open pour swim baits. I fish extremely clear water and enjoy tinkering with making baits as natural as I can. Thanks, guys Quote Link to comment Share on other sites More sharing options...
bryanmc Posted July 8, 2023 Report Share Posted July 8, 2023 I remember that post. For some reason I was thinking he mixed the sand with elmers glue, but I can't swear to it. Quote Link to comment Share on other sites More sharing options...
