Gallium metal - one troy ounce - .9999 bullion First predicted in 1871 by famed Russian chemist Dmitri Mendeleev and formally discovered in 1875 by French chemist Paul-Émile Lecoq de Boisbaudranm, gallium is a silver colored and fairly soft metal with a low melting point of 85.576°F. It is used in low temperature alloys, in thermometers as a non-toxic alternative to mercury, in semiconductors and other electronic devices. It is widely considered a technology critical element and ranks near the top of the British Geologic Survey's "Risk List". Inscribed on our ingots (and on our gallium containing jars) are the chemical symbol (Ga), purity (99.99%), weight (one troy ounce), and a serial number (this number is unique and will vary). On the reverse is our logo. These ingots and jars are nicely finished/etched, similar to those pictured. This metal is fairly soft so our ingots often have small edge dings, scratches and other small imperfections which do not detract from the inherent value of this unusual metal. Gallium also has a very low melting point (85.576 degrees Fahrenheit) and thus could melt if held in your hand for more than a moment or two or if shipped during warm weather. We therefore reserve the right to substitute the container form of our gallium for the ingot form if we are shipping during the Summer months or to the southern states, otherwise you might just open your package only to find a puddled mess. As always, weight and purity are guaranteed by Rare World Metals Mint. Metallic gallium is nontoxic. Various compounds gallium are toxic, including it's oxidized form. So as we suggest with all of our metals, keep them intact and in a safe place, do not ingest (or burn), and keep them out of the reach of children. Each ingot (or gallium containing jar) will be shipped with an assay certificate and every shipment will include our velvet logo bag. If you are not completely satisfied with any purchase from us, you have 30 days to return it for a full refund (buyer to pay return shipping). Domestic shipping is free for all orders over $199 (enter code free shipping at checkout). For orders of $199 or under, domestic shipping is $9.95. We will NOT ship our gallium products internationally. https://en.wikipedia.org/wiki/Gallium http://en.wikipedia.org/wiki/Abundance_of_elements_in_Earth%27s_crust https://nora.nerc.ac.uk/id/eprint/513472/1/Risk_List_2015_FINAL.pdf
