Need help identifying this Laboratory Glass Vessel

[cbotw27]

I got this at a Lab Surplus Auction and I have no idea what it is. Can you help? It is 16" X 16" X 10" with 1/4" clear glass walls

Did you wash your hands after handling it?

Thanks for taking the time to leave a stupid response. If you don't know you should keep your irrelevant thoughts to yourself
