A selection of six salts for student use in observing spectra of some fairly common elements.
Included are salts of barium, boron, calcium, lithium, potassium and strontium.
Also provided are a test tube and a holder with a length of nichrome wire for introducing the salts directly into the flame.
The test tube may be partially filled with water and the outside then dipped in a solution of the salt for introduction into the flame.
Each bottle contains .5 oz salts.
