Indeed.  Clay is just compressed silt from erosion.  Glaciation isn't
necessary to produce it, just time and pressure.

Unfortunately when you get clay from volcanic rocks, you wind up with
more rounded and less flat particles, and particles with high melt points.

When white guys first came to Hawaii they saw all of this beautiful red
clay everywhere and set up to make bricks... and couldn't because it's
not that kind of clay.  They wound up doing things like making houses with
blocks of coral, some of which still stand (as does the kawaiahao church
which was constructed in that fashion).  That's very labor-intensive and
not very sustainable, though.  So today most houses you see there are
frame houses made with wood shipped in from the mainland.

 Interesting. I can see some clays not being suitable for bricks, but
there is a long history of Polynesian pottery, including from volcanic
islands such as Fiji and Easter Island.
