In the "for what it's worth" category, when I started prototyping what became the 'Original Bubba Puck', I considered several different mediums for an "advancing bisquette". I'll spare you the reasons for failure/not selecting of other types, and just say that I landed on the aluminum as the best all around choice. I then spec'd the puck to potential suppliers as, among other requirements, 'food grade'. As explained, food grade was dense enough to reduce exfoliation during predicted usage....(a concern that a hospital might have when removing all aluminum cookware from their building as posted above).
As most of you know, I no longer have any financial or legal ties to the Bubba Puck makers, but just thought that you might want some background on why I still use mine with no ill effect, other than not remembering my name when reporters call for interviews, baldness, an intense desire to kill and eat King Salmon, and a propensity to see how fast ANYTHING I operate on land/sea/air can really go!!
