I'm trying to cook "authentic" pizza in a home oven. The recipe I'm following asks that you preheat the oven to the highest it can get (500°F/260°C for me) with the stone inside. So, I follow this instruction. For the first 15 minutes, everything's fine. Then, I see liquid forming at the top of the stone. Soon enough, tons of smoke is coming out and I have to turn on the fan. I decided to abandon my plan to create the perfect pizza because of this problem with my stone.
I think the liquid coming out of the pizza stone is oil that's been absorbed from past times I've cooked with it. It wasn't a problem then because I didn't preheat my pizza stone previously and only cooked at 425°F/220°C. Then, the oil heats up and evaporates into smoke.
How can I fix the issue of oil coming out and smoking up everything when I'm preheating my stone at high temperatures?
Edit: Just found out that my mom puts oil on the stone every time she cooks pizza D:<
