Yo! What’s up guys. I’m finally gonna start learning to sand cast so I could try gypsy setting some thicker pieces. Since I work out of an apartment, casting wasn’t much of an option. Now I should be able to cast at my grandparents house, but previously whenever I would try and melt metal down the most I could get with a mapp gas ts8000 torch was around 30 grams.
I don’t believe this is enough for thicker sand casts, and was wondering if y’all have pictures/suggestions for created some sort of firebrick insulation chamber for your crucibles before you cast. Like, do I need to get a specific temp firebrick? hard or soft ?
I also wanted to mention that I have an acetylene oxygen B tank system, but it’s a little torch and haven’t gotten good results with the rose bud tip.
Hope to see some of ur set ups! Thanks for reading.
