The most knowledgeable looking reply on that thread came from Karol:With that kind of temps and time you're going to end up with some really deep brown wax
"To sterilize beeswax you have to hold it at 160°C for two hours. Because beeswax has virtually no water of activation it holds bacterial spores in hibernation. There is a risk that when bees 'handle/work' with the wax, especially when they posit large volumes of water during honey production, that spores finding themselves at the wax-water interface may become activated.
Personally I think the risk is very low compared to the risk of honeybees picking up pathogens from their natural environment. I would be more concerned about heating beeswax to form polyaromatic hydrocarbons (PAHs) at the sterilizing temperature which are potential carcinogens and likely to leach into honey. "
Like overheating honey, high temperatures can produce potentially harmful chemicals.
I'm thinking I'll keep temperature below 100degC and try and solve my chalkbrood problem by better queens.
