ASU2. Then it made sense to see if i could make a mould without help at home. And i could. One of the reasons i wanted to do this was because an artist on instagram had posted a lead cast and said it heats at a low temperature and can be cast in plaster or wet sand. I have not tried this but i hope to cast this bowl in lead if i can after testing the process with smaller objects and maybe wet sand first. There are images of the mould making process on my instagram.
