Charcoal blocks for blowpipe 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 charcoal blocks for blowpipe testing of minerals.
Unfortunately, these handy, old-time mineralogy tools are difficult to find
for sale, and quite messy (not to mention tedious) to make for oneself.
We supply these blocks- actually, ours are not charcoal; they're machined
from solid graphite, much denser and more durable than ordinary charcoal.
We also have blowpipes.
Because of their toughness, our carbon blocks
last much longer than charcoal block and are therefore a better buy.
They can withstand enormous heat without being consumed. They're also not
nearly as messy to handle. When done with your assay, let it cool
and simply scrape the surface of the block with a razor blade or rub it with
sandpaper to prepare for the next test.CAUTION: carbon retains heat for a LONG time after exposure to the torch. Do not assume that it's "cool" just because it isn't glowing. Serious burns may result if the block is picked up too soon! Also, carbon dust is electrically conductive. Common sense dictates that the dust should not be inhaled or allowed near electronic equipment. By placing an order, Buyer signifies agreement to our Terms of Sale / Use. Eye, hand, and face protection must be worn when working with fire and / or chemicals!
