Uhm, Norman, it sounds like you have vermiculite and perlite confused.
Perlite are semi-hard, white-beige, though can usually be crushed to powder
by squeezing between your fingers. Vermiculite are the "miniature
loaf-of-sliced-brown-bread" that you describe as perlite. They are pieces
of the mineral mica that have been expanded by high heat.
