Potting electronics

I’ve just leapt without really looking. I mixed up some epoxy without really bothering much about bubbles and the like. For the single 2.5cm square mould I have selected, a depth of 1cm requires about 6ml of mixed epoxy. I used veterinary syringe measures (the sort you use to squirt a dose of antibiotic into your pet’s mouth) and mixed up about 10ml. Here’s the mould after 30 minutes, top view and side.

My guinea pig for vitrinisation is a resistor. If the process works I’ll be able to judge the thermal qualities of this embryonic mignon by feeding in current and seeing what it does to the temperature.
