I poured cold water into the IMUSA pot mug, then put the full mug on the JOGR stove. The water boiled while in the IMUSA pot mug. The wrapped area was cool to the touch immediately.
re-edit: Mark, if you are thinking of fully wrapping a pot without a handle, essentially making a permanent taped cozy, then it will take a lot of tape depends on the size of the pot. In my case I'll use the IMUSA 4.5 inch diameter has a 14 inch circumference. and the mug is about 4 inches tall, you are looking at 40+ inches of tape. That will register on the scale. I would prefer a removable cozy. If going in that direction, you can of course still get the 1.5 inch wide tape, but you can also look into buying a larger sheet... with the extra make yourself a fireman suit :)
Then again, just because I can handle the pot doesn't make the boiling water easy on the lips or tongue. So I used a spoon to blow on the soup to cool off before drinking.
The weight of the heat shield tape strip didn't register on the food scale. I barely used 1 inch x 2 inch for the knuckle protection, and 1 inch x 4 inch for the handle wrap.
Because the heat shield foil is corrugated/ribbed it adds a slight air pocket of 1/32 or 1/16 of an inch.
