Tappers,

Anybody do a demo with Cinnabar? It is a mercury crystal with a special
geometry. Anybody know more about it?

Do a little more of that work which you have confessed to be good,
Which you feel that society and your most Just Judge rightly demand of you.
Cultivate the tree which you have found to bear fruit in your soil.
If you have any experiments you would like to try, try them.
Now's your chance.
Henry David Thoreau, Journal entry, 1850.

JZ,

I just pour methanol in a watch glass with the following:

Cupric Chloride = Burns Green with prominant yellow line
Strontium Chloride = Burns Red
Barium Chloride = Burns Green
Lithium Chloride = Burns Red
Potassium Chloride = Burns Purple ( not real intense )

An old PSSC kit that I have has the following in it:

Potassium Nitrate
Potassium Chloride
Strontium Nitrate
Strontium Chloride
Cupric Nitrate
Cupric Chloride
Lithium Chloride
Calcium Chloride
Sodium Bicarbonate
Sodium Chloride

Sorry, haven't had any experience with Cinnebar.
Any idea about how many people are attending the workshop in Madison??

Dale
