Could go in either GQ or MPSIMS but how high a heat can ordinary household carpet withstand? If you temporarily set down a pot of hot contents (ie boiling water) for a few seconds and then pick it up again, does it harm the carpet or stuff underneath?
Google says nylon has a melting point of over 500F. Keep in mind that while boiling water is 212, the pot may be hotter, especially if you just took it off the fire/burner.
Can I ask why you predict you’re going to need to put a pot of boiling water on the carpet? Can I suggest that you really need to set it on the carpet, for some reason other than having the heat of the pot interact with the carpet, you set something down first, a trivet, a cutting board, an oven mitt etc.
FWIW, I’ve always heard that ironing clothes on the carpet will likely burn it, but (according to wiki) an iron gets much closer to the 500f limit of nylon.
212F won’t melt the nylon, but is there a chance it could damage the dye components, resulting in a discolored patch?
There are two different nylons that carpet is commonly produced from, and they have much different melting points.
Nylon 6,6 - 507 F
Nylon 6 - 428 F
And some lower grade carpets are produced from polyester fibers. Polyester melting point is 482 F
The most common problem with synthetic carpets comes from friction burns (dragging your heavy furniture across the carpet) which results in friction heat and fusing of fibers together.
