marble is less resistant to heat but might work if it’s not directly in contact with the ambers and a little away from the fire. Chemically it is CaCO~3~ and if you heat it enough it will start to decompose to CaO and CO~2~ and crumble. It is a similar process to what you would see in a cement kiln :); not exactly stable but also not dangerous if it happens outside.

do you want natural rock or is synthetic also ok? also do they need to be resistant to freezing water as well? its not clear if there will be any kind of roof above…
very conservative answer would be something like granite, diorite or similar dense rock. if you have protection from water you can also use more porous rocks like sandstone. - Comment on When your Powerbank is dying and u can smell electrolytes escaping 2 months ago:
hydrofluoric acid
Not sure if serious but just in case: why would there be any HF in a lithium ion battery?

If the fans are running at full blast, maybe you accidentally disconnected a temperature sensor?

How many PSUs are installed in the Poweredge server? In the manual it says it could be 1 or 2 and the power per PSU could be 1100W so if it is 2 * 1100W then that could explain why the UPS has problems with it.

leaded solder without an extractor fan
lead does not vaporize at the temps used in soldering.
lead free solder also needs fume extraction. even more so actually, because it is used at slightly higher temps. even with perfect fume extraction, leaded solder can still poison you, because you touch it and then touch your face without washing your hands.
if you are prone to allergic reactions from solder fumes avoid solder with a rosin core, use synthetic flux instead. - Comment on B’Elanna’s stance on afterlife. 7 months ago:
I think you can even draw a defining distinction there because if it is not believed then pseudohalucination would be the better description.
