TIL that not all white rocks are limestone

A drop of acid showed me to check more carefully.

Wait, you just used acid on a random rock?

People into rocks do this a lot to check what minerals are there. A bit of vinegar or weak acid can show if it's limestone. Saying it's 'random' misses the point of testing. But whatever, I'm just a guy who likes cool stones.
