+tiki Posted March 25, 2008 Share Posted March 25, 2008 Aloha everyone - prepare yourself for a huge post! I was going to wait till these little guys were finished before posting - but I just had to share! As you may (or may not) know, I enjoy making ceramic Tiki Mugs in my free time. A while ago I branched off into making some tiki tiles for our house. I was captivated by the process of hand-pressing tiles, and built my own tile press for my studio. Not only did the tiki tiles end up on our bathroom walls, several found their way into caches as a neat swag item. People enjoyed finding them, and I decided to make a few “dedicated” tiki tiles for geocaching - and the Clay TikiCoin project was born! I thought I’d share the construction process with you in case any other geocachers wanted to give it a try. I should note now that these coins are non-trackable, NOT for sale, and are trade/swag items only (hopefully I can therefore discuss them on this forum). Here you see the master sculptures. I decided to make the coins around 2 inches in diameter (any smaller would make pressing the clay difficult) and sculpted the masters out of grey Super Sculpey. I took care to avoid any undercuts and I did not bake the clay. For the first 2 coins I went with a stone block Tiki Idol face and a Spooky Skull. I built boxes around the finished sculptures... ...and carefully filled them with plaster. I was extra careful to avoid trapping air bubbles on the surface of the coins (I did end up with a nasty one in the skull’s eye though, so I have to correct every skull coin I press). Once the plaster sets I remove the wood walls... ...And carefully lift away the plaster mold. Here you see the negative image of the Stone Tiki Idol (with dried clay bits from a test pressing). I stamp the back of the clay coins with this AMAZING clay stamp I had machined out of brass by the amazing fellow over at www.claystamps.com - he does great work! Here are several pressed coins on the drying rack. I’ll get some shots of the tile press in action later on. These are test coins - and the clay I used is way too gritty for this type of thing. I’ll be switching to a proper clay this weekend when I crank out a bunch of coins. Here you can get a sense of scale and a peek at the back. Don’t bother going to the website on the stamp - I haven’t put it together yet! I still need to bisque fire these in my kiln, glaze (color) them, and then send them back into the kiln for a final firing. I’ll post more photos as things progress!
