Hi - I stopped using talc and I use the talc baby powder alternative
and I think it’s made of cornstarch and think it works great. I
brush it on with a very soft brush and then blow the excess away into
my dust sucker. My pieces have a lot of texture and polished areas
too and have not had problems with surface porosity.
Right now I use the teal Kerr wax - what do you like to use?
Best, Jennifer Benusis
