Gummite is a rare radioactive mineral, a mixture of uranium minerals, oxides, silicates, hydrates and hydrous oxides of uranium, derived from the alteration of uraninite. It is named for its gum-like consistency. Here you see a layer of yellow-orange gummite on a matrix of pitchblende. Hard to obtain! From the collection of noted California collector Charles Hansen.
