Update for those curious about the ThermiPAQ clay heating pads: gave it a test run today to see how it works. I must say I'm rather pleased with it! Placed the clay pack in the little cloth sleeve that comes with it, folded it in half and heated it for about 1.5 minutes in a ~750 watt microwave. Immediately after removing it the pack the temps varied: the folded side ranged from 102-122F and the outer side ranged from about 98-105. Put it unfolded in the 10gal Sterilite bin I bought and let it sit for about 15 minutes: temps measured 90-100F overall on both sides. 45-50 minutes in and the temps are all around 90F. Keep in mind that this is WITHOUT insulating the heat pack any further (wrapping it in a towel will be my next experiment), WITHOUT insulating the bin (I had originally planned to put a thin layer of aspen down for bathroom needs, but it's going to stick all over the terry cloth-like cover for the pack so I think I'll use a towel to cover the bottom) and in a room around 68-70F.
More experiment results to come!![]()
