    This is my first time for maceration, I took a 5 gal bucket and placed enough water in it to cover my deer skull, I put a 300 watt aquar. heater in on 90 degrees and placed it in a broken chest freezer outside my shop, it is around 30-40 degrees here outside, will that be enough insulation to keep the process working?

    That will work fine. Just keep an eye on it.

    That's what I do except I put and old cooler with heated water and aquarium heater in the freezer fill cooler 1/3 with water then put 2 skulls in separate buckets with skulls in cooler This eliminates having to change the heated water (just add more as it evaporates. It is like double insulation I cant close the cooler and you do have to open the freezer like every 2 days quickly so that you do not get mold on the antlers. If you do just hose them off and degrease. Works great.

    That should be enough but, as Gill said, if you half fill the freezer (if you can) with water and heat that water instead you can set several buckets inside full of water and everything will be heated equally. You can even add a tiny circulating pump to keep the larger amount of water moving so that there are no cold spots. If you stay the same and are still concerned with heat loss you can easily make a box of that pink foundation insulation around it. It could be buried under snow and still be 90 inside.

    just a FYI i put a 200 watt heater in a 5 gallon bucket, uninsulated sitting on the ground, starting at around 50F water temps and it warmed up to and maintained the 90F i was requesting in 40F ambient. no cover. So 300 watt with insulation is plenty
