I have a question, not sure why I have not tried this myself. I'm wondering if anyone has tried using aluminum foil under a pizza (in the same way you can use parchment paper). I have used parchment paper many times to help me make the biggest pizza that will fit on my cooking surface.
It works fairly well, not as good as sliding it right onto the stone or steel, but (I think) 95% as good (or more). Right now I'm using Lloyd Hex Disks (picture below) so I can cook a 16-inch pie on my 16.5 inch stone and it works great.
So now wondering why not just try aluminum foil - seems like it would work better than parchment paper (no burning worries) and it must be almost thermally invisible- but maybe there would be sticking issues with it. I usually pull out the parchment paper (or Hex Disk) once the skin firms up and finish on the stone or steel. No sticking issues - but any sticking would be a major bummer and slow down or ruin my workflow.
Has anyone tried aluminum foil - if so, how did it work?
