@andrew_leo : Welcome to my office and the reflection of my mind.
One of the questions I get a lot about my work is the process for building for my big ol’ body. Here’s the easiest description:
SO YOU WANT TO MAKE PIECES FOR YOUR BODY. -
Do you need to cast your whole body in duct tape and then plaster a 20% enlarged version? Not necessarily. You’d just be a crazy person like me.
Instead, you could use old blocks of clay as the base and then measure out a slab to build off of that, accounting for shrinking clay. The rule of thumb is that you need to enlarge your measurements 20% to account for shrinkage/warpage/comfort (use the metric system for easier math). Sculpt the slab to fit, taking care to account for extra room for your nose and forehead — this will matter as those can’t get taped down to fit like ears. Give yourself extra wiggle room.
Then add some thick plastic, a hand towel, and start making. I follow the mindful approach to slowly dry everything for weeks to prevent cracking (but I often cheat and create a fan tornado drying system to circulate air around the piece, not directly on), and then I follow the #BruceDehnertNoBlowBisque cycle that @jim.lawton gave me.
For glaze, I use majolica as a base and spray about ten layers of overglazes and thinned Duncan Envision glazes. Then, I underfire my mid-range b-mix claybody to cone 02-2, giving it a 30 minute hold to get all goopy. If the glaze turns out—great!—but more often I tend to keep adding layers of glaze and sand-blasting when I need to.
