Maybe something like a nice metal tank that works the same way as a polycarbonate one. I was gonna order a bunch of them, but now I'm kinda freaked out about them. They're expensive if I'm gonna keep cracking them. I put some grape in the 1st cracked tank. So far, the crack doesn't seem to be getting worse.
Pyrex is absolutely possible. If done right would be nearly as strong as poly or lexan. The real problem is cost. It would have to be custom made and that would be SUPER expensive. It would have to be lab grade to stand up to the abuse. I doubt were likely to see a production pyrex tank anytime soon from any vendors.
