Are there any restrictions on these metals in your country, or are they just hard to obtain?
-Mark
Chemicals here are both hard to obtain for privates, and restricted by laws for at least half of the elements.
For the common substances that can be used in dangerous ways, or that can be also just dangerous themselves, as example, if i want to buy them, i can't ..... need a certification that say that you've followed specific courses for handling them, a certification for industrial use need (that say that you need it for your work in an industrial environment and under health office control, i mean), and you have to sign a special national register each single time that you go to buy one of them, that report all your personal data and all the quantity of any buyed element ..... and for a good part of them, you also have to present documents that certify where and how you used them, quantities, and wrere, how and who managed the related waste material, and the quantities also have to be coherents, you can't sign for 100Kg of mercury, then document waste treatment and disposal of 50, as example .....
and for the other half of the table, selling, buying and use is reserved to universities labs, medical environment, specific industries and research centers, and with much more restrictions than before ..... and other than this, also where the materials are available, they sell you only industrial quantities, or lab sampling ..... mean, as example, 1 Kg minimun of element 99.9% pure for industrial work (at high price), or 1 to 5 grams "extra pure high grade 99,999% sampling quality" elements (at absurd prices )
Then i see internet sites like unitednuclear.com, that sell to anyone in the US so much substances that i can just dream to have (and i think i can't buy from them, cause if our custom see words like "sodium", "cesium", "indium", and so on, in the invoice, they send me directly police and NBC squads before also just think "what the hell is that ?" ) ..... i'm envious, really
