I was going to make these blood slide lollipops and it says you're supposed to use parchment paper, but I don't have anyI read that you can use aluminum foil and spray it with cooking spray? Would that work? Thanks x
My dog Ok, I'll be seriousLeatherCotton, Jute and wool are both porous, letting heat escape; even if wool is very warmPolyester, and Rayon are plastic fibers, and take on the tempature of whatever it is around them (If it's hot out it will be warm; if it's cold out it will be coolLeather isn't porous like woven fibersit's solid- it's constructed out of protiens designed to keep something warm; think about ityour always warmer on the inside than the outsideI hope that helps!
To be a good insulator you want something with a low thermal conductivityThe thermal conductivities of some of those materials you listed: Cotton: 0.03 (in W/m/K) Polypropylene 0.1 - 0.22 Dry leather: 0.14 Wool: 0.07 I'm sure if you check some other sources you can find thermal conductivities for the other materials tooSo far cotton has the lowest thermal conductivity, so it would be the best insulator.
YesYou typed what I was thinking before I clicked your question; the foil must be sprayed with cooking spray or rubbed with margarine, shortening, or oil to prevent sticking.
