    Glycerol to calibrate refractometer

    Surely this is a much better substance to calibrate refractometers than olive oil. Refractive index of 1.4729 at 20C. Maps to 25.5% water content. And will not vary from bottle to bottle. And if you make your own fondant you will have this in the cupboard anyway. Seems like a no brainer to me.

    Yellow pollen

    Pale lemon yellow pollen coming in by the leg-load. All the ladies carrying the same. Not seen it before today. Any ideas? I'm guessing it is off a tree as the volume coming in is amazing.
