lets just say they use starphire glass in reflectors for solar power plants for a reason. i was just wondering if it would be possible to build something like this http://reefcentral.com/forums/showth...ighlight=nTOTM out of starfire glass, and could it be done safely with no braces around 15-25 gallons ish?s safely?

Yes, but it would be near double the price. Same price, if not a little more, than acrylic. I priced out tanks the other day. Unless you go say glasscages.com route or something. You just have to increase your thickness a bit, which for starphire is a bigger jump than it would be for regular glass.

Absolutely, the glass thickness required will depend more on tank dimensions than volume.
Pretty much any size tank can be braceless and constructed from starphire glass. I'm in the process of setting up a 200+ gallon tank which is both starphire and completely braceless also often referred to as rimless.
