As I read this;

"but have a paper towel lining with no moisture in the pan that is in the pan that has water would that dry my buds keeping the thc in place? "

There will be no butter involved.

Just a paper towel or two.
The gentleman is just looking to limit the temperature to a safe range.

@DCG

I would advise against the hassle and steam of a double boiler
240 degree oven for 15 minutes will dry and decarboxylate at the same time.
It will be dry, and probably a li'l nasty tasting but it will allow you to asses your harvest.
