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.
Reading the wiki article reveals they used whoever was available and cheap: Soyus 2 (Russian, until 2022), LVM 3 (Indian,since 2022), Falcon 9 (USA, since 2022)
It makes sense for a company that does not build rockets to just use whats on the market.

joah ich würd sagen das ist noch einer der harmloseren stoffe die man in eine waschmaschine tun könnte.
hydrofluoric acid
Not sure if serious but just in case: why would there be any HF in a lithium ion battery?
Are the parts both made of PLA? Silicone caulking would be elastic and easy to break but it might also become unstuck on its own since the adhesion to plastics is not great.
Rubber cement would also work in principle but it might not be reversible at all and depending on the solvent and what plastics you used it might damage the plastic parts while the solvent is drying. Acetone can damage ABS plastics for instance.
Would a low-temp hot melt gun work? They can operate as low as 120°C which might be low enough to not destroy the plastic parts.
yeah, but thats not really saying that it isnt cruel.
So 3 years of malnutrition is not cruel?
the country was treated generously for fear of it going to the other side
In Germany the shortage of food was an acute problem. […] the average kilocalorie intake per day was estimated to be 1,080, […] millions of people are slowly starving.
Germany received many offers from Western European nations to trade food for desperately needed coal and steel. […]. Denmark offered 150 tons of lard a month; Turkey offered hazelnuts; Norway offered fish and fish oil; Sweden offered considerable amounts of fats. However, the Allies disallowed the Germans to trade.
So "generous" is a bit relative here. Germany was not subject to the most extreme plans for de-industrialisation, which some had planned. But at the same time there was definitely planned hardship, which had no reasonable explanation based on security.
