    I'm voting for Aerogel myself. It's transparent and a very good
    insulator.

    Here's a fellow selling a big slab on ebay. 

    <Snip - Sorry, No eBay links on Orchid please> 

    I don't know how high the bidding is going to go, I'm guessing a
    couple hundred dollars. 

    It is rather fragile. It may work for soldering, but it might
    shatter if you were to drop a hammer on it, so don't drop hammers on
    it. People make fiberglass reinforced composite aerogel, but I lost
    interest before trying to hunt down a supplier. 

    It is very pretty, but too soft and gritty to make jewelry, I think.
    (I got to handle some a long time ago at a visitors center at a lab.)
    Unless you made a protective cage.... hmmm... aerogem.com makes
    little glass pendants with aerogel in them, but they are very boring.
