wax ingot ratio for emax venners

[benigna]

hi guys
is there a formula to use to determine the weight of old emax ingot to be used for wax? i know that each ingot takes 0,75g wax, how about if i have more weight of wax than what one ingot can compensate how do i work out the difference if i want to use an old ingot

I think Mark Jackson has the formula

We are starting to reuse the ingots. I weigh a new ingot first. Then I weigh the used ingots. But I learned the hard way that you can not have 3 used ingots in the ring, they don't melt well. You can use 2 used ingots in the ring. Try to get the weight as close to what a new ingot weighs. If you need to, use a new and chase it with a used one. I don't quite have a defined wax for each unit yet, still working on it.
