I've made a number of ceramic molds for slumping fused glass into bowls. As well as wooden templates for ceramic mugs. I've devised a few carrying tools to move glass frit paintings from my studio down to my barn where the kilns sit without spilling the glass. Or were you only asking about digital tools? I haven't really made any of those. Making physical tools feels much more satisfying these days.
Can you fire ceramic in a house oven? Or do you need something more industrial?
Low fire clay fires at 1060°C+ and high fire clay at 1222°C+.
