And looking around, I head straight to the Aerogel. Surely they have it. It’s totally space-age–NASA uses it after all, plus it makes for compelling demos. And since it’s generally considered an expensive material, it can only be cheaper online right?
Inventables has something they call “Flexible Aerogel Fabric” but unfortunately they’re out of stock. But they do tell us it’s only $3-$10 per square foot. Not bad at all.
For the real stuff, you have to visit the aptly named United Nuclear Scientific Supplies. Scroll down to the bottom and you’ll see 5 gallons of Aerogel granules for $300.00 USD. That’s more like it; quite a suitable price for something NASA uses.
I love specialized stores like Inventables and United Nuclear. And another favorite for the list is LeSanctuaire, which provides “only the rarest choice ingredients” to “fine dining restaurants and professional chefs.” That got me thinking, how do the traditional “expensive” ingredients used in cooking compare?
- Aerogel
16 oz $300 (1 oz $18.75) - Vanilla Beans
8.8 oz $110 (1 oz 12.50) - Truffles
8.8 oz $135 (1 oz $15.34) - Saffron
1 oz $190
(All of the ingredient pricing was pulled from LeSanctuaire’s site.)
Saffron wins this round.
