Tankards - does it change the taste?

[Brewbob]

My B-in-L got me a tankard for my b'day, I've started using it, and I think it does something to the beer, I like it, seems to keep it chilled longer. The down side is you can't check the clarity of your brew. The jury's out...

Gonna have to dig out my tankards and make some side-by-side comparison tests :drink: :drink:
