Searching for a fireproof sponge? (I know this is a bit off topic, but I don't know where else to ask. If you know a better StackExchange site, please tell me)
I'm working on a project, and I want to basically create a &quot;flaming sail&quot;. For this, I'm planning to drench a cloth in methanol and then lighting it, and for this, I need a fabric that both retains a lot of moisture and is flame proof, as this should be reusable.
Fiberfrax is the standard material for high temperatures in refinery, chem. plants, etc. There are also other brands , all readily available on the net. Ads do not give detailed composition other than &quot;alumina and silica&quot; .  Fiberglasses may not have  high melting /softening temperatures. There are higher temperature fibers like thoria, but are expensive and not easy to find.
