Hello potters, I really appreciate all the information you share on this website and, as a not-so-experienced potter, I try to experiment in my studio. I'm about to take part in a fair and sell my stuff for the first time, and as I dont have enough time to experiment before this (2 weeks to go!) I would like to ask you: Is it possible to use vaseline instead of was resist in glazing? Does it leave any marks on the pots? I imagine it is not a very friendly material to burn, but I may not have time to search for wax (i havent found it yet here in SÃ£o Paulo - Brazil) and Im planning on cleaning most of the vaseline after glazing. Do you think it is a good idea? Thanks!
