How to Boil Milk without Burning

I breastfed Elena until May this year, so she have never eat any formula. Starting with September last year, I started to give her whole raw milk from free range pasture raised caws. Because we didn't have all the time a trustworthy source of buying this kind of milk, sometimes I prefer to boil the raw milk.

In this situation, the main issue is not to burn the milk. So, I invented this method of boiling: bain-marie with a cast iron pot.
