I think you’ll find vintage silicone to be far superior.
Seriously, though, surely silicone’s not the right material for this? Certainly silicone baking stuff seems to heat up pretty quickly.
I was given a cast iron pan (a Wagner?) which came with a padded fabric sleeve (like a miniature oven glove) that fitted over the handle- this works very well, despite looking rather more rustic than silicone.
