Platinum Wire for qualitative analysis of minerals
The classic texts (i.e., Frederick Pough's Field Guide to Rocks and Minerals,
Orsino C. Smith's Identification and Qualitative Analysis of Minerals,
etc.) recommend using platinum wire for flame and bead testing of
mineral samples. Platinum (Pt) is resistant to attack from most chemicals
and does not contaminate bead or flame tests with any color of its own.
We sell platinum wire loops for doing flame tests and bead tests (specifically,
the classic sodium carbonate, borax, and "salt of phosphorus" tests).
This item consists of approximately 2" of Pt wire set in a 4" glass rod;
the end of the wire is curled into a loop about 1/4" in diameter. The wire
itself is 28 AWG (0.32 mm diameter). With proper care, a platinum wire
loop will last indefinitely. Make sure your assay material doesn't
contain arsenic or antimony, which can embrittle the wire and cause it to
break. 
Platinum wire loop for bead tests / flame tests.......................................$18.95 each 2-3 pcs: $18.50 each; 4-5 pcs: $18.30 each; 6 or more pcs: $17.95 each
Wear safety goggles and / or face shield and carry out all experiments in the proper laboratory environment. Platinum acts as a catalyst for many reactions; keep it away from methanol and from mixtures of H2 and O2 gases.
