Hello all, I'm working on a product at the moment which will be slip cast from a ceramic, but it requires some accurate holes in it for a hinge. Ceramics manufacture is a hit and miss affair at the best of times as you have to take into account the shrinkage and the skill of the manufacturer. I've heard mentioned a few times the idea of cutting a rough hole in the ceramic before it's fired, then casting a resin or similar plug into the hole which can then be drilled or cast using a jig to achieve a more accurate location. My question is just about the logistics of such a process. Has anyone done this or similar or can point me to some info on how this might work? Thanks in advance!
