What exactly is necessary, in my mind, everything is clear.
If you have any specific questions - ask.

How does the temperature control work?

Heats up very quickly, such as a power of about 3.5 kW and a small volume of the chamber. The inertia of the upper side of 20-30 degrees C, the lower 2-3. It is only necessary to get used to it.
To reduce the heating capacity built into line powerful diode that allows two times lower AC power.
I hope that the correct answer to your question.

Nothing specific. I just meant, i'd like to see/hear more of it like being in action.

This is crazy.... Asbestos has a direct link to Bronchocarcinoma and Mesothelioma. I hope you are wearing a mask when you work with it

Thank you! For something that you think about my health. Always will wear a mask.
About the carcinogenic properties of asbestos I know. Asbestos-exposed areas I smeared fireclay clay. If cracks will continue to gloss over.
So far, I can not spend valuable work with the furnace, we must also beefed up. Time is also not enough
We sell loose asbestos in the store and it is often used for thermal insulation.
We have many sayings on the subject of health. For example: "What does not kill you makes you stronger." But it's all a joke. Once again, thanks for the warning!

Most of the threat from asbestos is air born particles. In California I could not tell you how much water pipe is in the ground that is made with asbestos in it. More feet than dollars in the national debt I would guess. It's breathing it that will kill you.

Yeah it's funny, you mention asbestos in the US and it's like there was a radioactive leak. In other countries you probably get a "huh?" from people.
Like anything else just take caution around it
That's a quite a setup there - some nice engineering.

es. But the asbestos blanket shown in the pics of the OP is exactly what is dangerous about asbestos: airborne asbestos particles galore.

most of australian housing from about 1930 -1980 seems to have been constructed in part from asbestos. its a nightmare from a renovation point of view.
