SHARPiE said:Put on a rubber glove and touch it, is it hard? Soft? Spongy? Powdery? Slimy?
Is that the only pic you have?
Post a few more from different angles and of different rocks if it's on those too.
What substrate are you using? Sand? Could it be tiny particles of sand?
What type of rock is it?
Where did you get it from?
