Even one preoccupied has to make room for his obsessions. (Further obsessive tendencies revealed here.)
For quite a while I have been persuaded by experience that my Nigel Rudolph mug retained heat better than any other mug in our cabinet. I asked Nigel and his wife Cheyenne about that recently and they could offer no reason why that should be. These are not, you should know, ceramic hacks. Nigel and Cheyenne know much about the science of clays, and as far as they knew, there was nothing in the mug itself to bring about my perceived result.
So, making tea for a guest the other night, I decided to put my perceptions to the test.
I selected three mugs, a tall skinny Hope Presbyterian Church mug, a wide mouth Nigel Rudolph mug, and a medium girth Krispy Kreme mug. I put 7 ounces (by weight) of hot water in each, and took measurements every minute for ten minutes, then every five minutes, and then at 60 minutes.
This was a very efficient use of time, as our guest, Barb, and I sipped our tea and talked while the measurements were being recorded.
Our guest, though, laughed at me. We love her anyway. I have been accused by friends in Los Alamos, NM (having, in my estimations, more PhDs per square inch than anywhere else on the planet) of suffering from LAPD, (Los Alamos Personality Disorder). Diagnosis is, no doubt, hereby confirmed.
What we discovered was that my perceptions were wrong. The wide-mouthed, Nigel Rudolph mug lost heat at a greater rate than the tall and skinny-mouthed Hope mug. Our conclusion was that the surface area of liquid exposed to the air is the variable which determines rate of cooling.
I also concluded that I simply need to drink my coffee faster. All science aside, I’m not giving up the aesthetic and personal pleasure of using Nigel’s mug!
