    Thanks dorff. Thant clarifies things a bit.

    I'm not sure about the statement that NaOH is water free and can be measured accurately however. Perhaps, you meant something else? I can place a small quantity of NaOH on a scale and watch it get heavier as it draws water (and CO2?) from the air.

    Well, if you work quickly it does not affect the weight that dramatically. I don't dawdle when weighing NaOH, and I close the container immediately when done. Obviously it has to be stored in an air tight container and it helps to live in a dry climate, too. If it looks wet, it is not anhydrous enough to start with.

    Dorrf I have been following with interest. Being a fellow antipodean and going into summer this formulation one I too will be trying given the amount of rosemary we have about the garden. Will also give the mint a burl when it takes off in about a month or so.
