Sorry. I know I shouldn't--but may I ask why when you spill slip you =3D
don't just mop it up right away before you slip on it?

Well, it appears the forgiving slip does not forgive, it forgets...

Your bisque is "preshrunk". Apparently (you do not give recipe) your =3D
slip is not. I think that is your problem.

There are recipes aplenty for slips for bisqueware. I know Rhodes gives =
some.But I am here and my books are not.

So. Check out Rhodes's "Clay and Glazes"

Or calcine some of the clay in your slip.

Assuming your slip is 40% kaolin/40% ball clay/10% nephsy, 10% silica, =3D
experiment with calcining 10% of each clay.
Experiment with calcining ALL the kaolin and none of the ball clay. =3D
Test. To calcine you just need to bisque the clays.
You can buy calcined clay, but why waste $?

There also are pyrophilite slips. Very good. But try this first...
