That could be the triple point of one of the nine isotopic variations of water molecules instead of the "natural" mix of molecules of all mass numbers. > ...

The value 273.16 K for the triple point of the "natural" mix is a constant *defining* the present kelvin scale. This triple point is not a variable under the present definition of the kelvin as Joe would have us believe. Gene.
