Ok, so, after careful consideration, I decided on using the recommended
50/50 mixture of beeswax and rosin to pot my two transformers. However, to save costs, I was originally going to try using a smaller housing, which would use 2 lbs of wax-rosin mix instead of the 6 lbs I would have originally needed, but instead of switching out the housings for a smaller one, is there something I can place inside the existing housing that's cheap, would also serve as an insulator like the wax will, and won't be burned or melted by the wax pour? The same idea as using extra stones or bricks in a toilet fill tank so it doesn't use as much water. Thanks!
