texturized espresso cups

Introduction: Here's the first attempt at creating a silicone mold for casting ceramics or cement espresso cups, and it's also my first time designing with displacement mapping - really exciting stuff. As it's not all done yet, this will remain marked as work in progress and will be updated continually. Instructions: The files include two different cup versions that can be used as normal cups (when printed in an appropriate material) and a bowl to encase the silicone mold. There's also a frame that holds the espresso cup upside down. You have to glue them together like in the screenshot provided, then drill a small hole into the bottom of the cup + frame to let the silicone fill out the cavity. Attach the frame to the bowl so it resembles the aforementioned screenshot. Now slowly pour the prepared liquid silicone into the pot until it reaches the glue-mark + a few mm more. Make sure there are as few bubbles as possible (using a vibrating platform can be helpful). After the silicone has hardened, remove it from the pot, cut it open alongside, carefully cut out the handle so you can put it together after removing the cup. Place the empty silicone mold into the pot again, check that it all aligns and start pouring your ceramic mass or cement or whatever. Reuse it until you've bugged every person you know with tons of selfmade espresso cups. Cheers. Questions: Further plans: Glazing. Has anybody here done that yet? Is it possible to glaze cement casted things in a kiln? Is there something like cold-glaze which is food- and dishwashersafe? I'd be glad if someone could give me some advice here.
