I have heard that Nepheline Syenite is somewhat soluble. But you use
problems, as in plural. I would like to know more please. Thanks.

Hello Leland:

Even though I used "problems", the only trouble I've had with Nepheline
Syenite is the deflocculating and settling of glazes from some soluble
Na. It's a very high sodium material and glaze fit is sometimes tricky but
it's really not too problematic in my experience.
