Hi, I’m sorry to learn of
I’m sorry to learn of your experience. I do agree that firing molds should come with their own usage instructions. I have had to contact Delphi several times when uncertain how to arrange the glass or to prep the mold. I also believe molds should come drilled when sold. Some people don’t have the tools for doing drilling their work. Maybe bisque molds easily break during packaging if pre-drilled? However, there is absolutely no reason why stainless steel can’t be sold pre-drilled! Good luck with your projects as well as your shopping experiences.
