One is covered in heat-resistant silicone, the other is covered in flammable wax.
It’s really grocery stores fault. They sell them right next to each other and often have like 8 different brand choices of one but only 1 or 2 of the other which is nestled somewhere inbetween the others.
And I have yet to see a single one with a giant badge that says “not for oven use!” Moreover, wax paper is always marketed as “microwave safe.” I know a microwave is not an oven, but it’s not ludicrous to equate the two.
It’s an American language fault. Parchment paper is called baking paper elsewhere. You can’t make a mistake when choosing between baking paper and non baking paper.
Parchment is something you write on, as far as I’m concerned.
In Germany we just take regular “Backpapier” (literally “baking paper”) and put it in the oven.
It’s basically just Polytetrafluroethylene, better known as PTFE or Teflon™Which one is which?!?
You understand that the reason we make candles out of wax is because it’s a solid fuel, right? The same reason candles work is the reason wax paper isn’t oven safe.
A lot of people think that the wick itself is the fuel. I only recently realized that it’s “wicking” up melted wax, and the wax itself is the fuel.
