This is an e-mail I saved off of this list sometime last year. I hope
Here are a few chemicals you can use to soak pinecones, wood chips,
newspaper, etc. Wood should be soaked for 1 or 2 days submerged in
solution in a burlap bag.
Blue - Copper Sulfate
Yellow - Table Salt
Red - Strontium
Purple - Lithium Chloride
Vivid Green - Borax
Apple Green - Barium Nitrate
Orange - Calcium Chloride
Lavender - Potassium Chloride
Emerald Green - Copper Nitrate
USE RUBBER GLOVES, APRON & FACE PROTECTION<
mix at a ratio of 1/2 lb to 1/2 gal of water.
Or, check out the hardware dept at Wal-Mart in the wood stove section,
they have burn sticks to produce multi-color flames.
lithium salts for a deep red
strontium salts for a crimson
calcium salts for a red
barium for a deep green
lanthanum for a definite purple (much better than potassium)
most of the "rare earth" elements, as soluable salts, will produce
A possible side excercise, once you have selected and acquired the
you want, is to dip into the metal salt solution a small piece of wire
a small loop in one end and the other end in some sort of thermal
such a being sealed in a piece of glass tubing (another item that should
available from the high school lab). Placing the metal-wire loop into
flame of a propane torch (the hardware store variety) will yield the
appropriate colored flame. This will allow the boys (or who ever) to
experiment with different metal solutions and combinations before
the "final product".
