In the US, the sale of a whole list of chemicals is to be prohibited, unless the buyer owns a $1000,- license!
On the list: Aluminum and Aluminum alloys, Magnalium metal, Magnesium metal, Magnesium/Aluminum alloys, Titanium and Titanium alloys, Zinc metal, Zirconium metal.
United Nuclear, who are "Supplying the science hobbyist, industry, government, schools & universities since 1998." are asking for donations to fight this stupid silly action.
... Land of the free, home of the deprived.
