Hello all. For the last few months, we've been having trouble casting our Sanders waxes. We've been getting blisters which are clearly from air escaping from the models (not surface air bubbles) and flashing. We are casting jewelry objects in sterling. The parts are always solid and have a light coating of mineral oil. We don't use a de -bubbler. Our investment is Kerr Satin Cast and our burn-out is entirely successful for our regular waxes. I've always had some trouble with the blisters but the flashing is new in the last few months. Has anyone else experienced this recently or does anyone have any words of wisdom? Should the burn-out be different for these waxes, perhaps?
Thank-you,
Cate Minich
