How to recognize it

Trögerite can be identified by its low hardness of approximately 2.5 on the Mohs scale, which makes it easily scratched by a copper coin or a knife. It typically exhibits a yellow to yellow-green color and a vitreous to pearly luster. The streak is white or pale yellow. Due to its low hardness and specific color, it can be confused with other uranyl arsenates or hydrated uranium minerals, but its distinct chemical composition and crystal system aid in differentiation.
