I was excited when I found this 1950s aluminum ice cube tray. I couldn’t help but imagine a wealthy Palm Springs divorcee lounging poolside, brightly colored fingernails on her sun-leathered hands, levering ice cubes for a Tom Collins. The best thing about using aluminum is that it makes ice much faster. Plastic and rubber trays are quite inadequate, as they act as insulators between the freezing cold and the water.
And aluminum doesn’t just conduct the cold air in the freezer faster, it also makes the cubes melt faster so they’re easier to remove. Unfortunately, things become a little more complex when taking a closer look. For decades there has been a discussion about the possible link between Alzheimer’s and the use of aluminum kitchen utensils. The discussion came up in the 1960s when autopsies found unusually high amounts of aluminum in the brains of Alzheimer patients. But most scientist believe that the high aluminum concentrations are a result of the Alzheimer’s and not the other way around. To this date, no proof has been found for a link between aluminum and Alzheimer’s. (More at our article devoted to the subject of aluminum and health concerns.)
