What is the hottest external thermal mass anyone has ever heard of? Also what would is a safe thermal mass high temperature.

Philip Baldwin : You must school your self to understand two specific conditions, 1) the Materials ability to adsorb the Freaky Hot Exhaust Gases, its

Specific Heat Capacity, and its ability to deliver that Heat Energy through itself to the Surface of our Cob Thermal Mass Bench, its Thermal Conductivity


As Soapstone has exactly what we want I have shared a link below :

Please note that this site traditionaloven.com is a vast source of practical information mostly without a lot of jargon using simple terms


More technical information from the engineeringtoolbox.com site with link

Sorry this was not more timely, hopefully it will make up for that by its usefulness, For the Crafts ! Big AL

Safety is relative to usage and location. A surface accessible for long-term contact by children should not exceed a temperature that will scald, that might be 105F to 130F. A surface only reachable by intent can be hotter depending on location and audience...

The safety of a given temperature is also dependent on its conductivity, which is how fast heat travels through it. Metal is highly conductive and can cause a burn quickly, while cob is less conductive and will take considerably longer to cause damage on contact. Soapstone is relatively conductive and may need to have a lower surface temperature than cob to be safe.
