Hi guys, just a couple of quick ones, yes I did have a good search but didnt find the right answers, I'm looking to make some fermenting weights to put in my fermentation kits, they weight down the cabbage when you are making sauerkraut, I live in Australia and all the good products come from the US, pastage as it is spirals affordability out of contention, so a couple of ideas about making my own. Firstly I was thinking pottery and a food safe glaze but also glass, a friend told me you can melt powdered glass with a MAPP torch but it seems if glass cools too quickly it fractures and I dont want it exploding in peoples jars of sauerkraut. So I'm guessing a kiln is the only way to do both pottery and glass products, is is the MAPP gas route feasible? I was thinking melting glass into a mould might be the best idea, though I'm not sure what this would have to be made of.
This is the sort of thing I'm talking about
Thanks for your time and ideas!
