Lou,

The membrane or multiple recrystallizations are definitely more trouble than I would bother with. I knew before asking it was cheaper to buy if I had any value on my time but it fit under the category of nice to know.

The color test with sugar is nice to know and simple. It is similar to what I used to do but I failed to note the color of the flame while aiming.
