How to protect intelligent fluids from heat damage?
So, Second Earth had/has a firearm problem. Since my magic is really just advanced science, I can't create firearm-disabling fields, so instead, I created a spell that should be able to ruin firearms.
The "Gun Jam" is a strawberry-flavoured intelligent fluid, that can move on its own and harden in response to physical trauma, meaning it's shear-thickening, though the increase in shear viscosity can be controlled.
Upon coming into contact with a firearm, it can seep into its internal parts. The jam usually targets the rifling and the firing pin, as it can block both.
However, there's an issue specific to it.
It's a thing on Second Earth that micromachines can't stand heat and guns can get pretty hot. Of course, in intelligent fluids, the micromachines are suspended in a liquid, but that won't be enough to completely alleviate the issue.
How can I minimize heat damage to the Gun Jam?
