The white slip I use on the clay slabs while they are wet is Kurt’s Shino Slip.  This slip is fairly high in sodium, giving the surface a buttery texture when fired to ^6.  It also has some body to it, allowing you to create thick textured areas that don’t melt out in the firing.  In oxidation the slip stays beautiful white – though it can be a bit transparent.  In reduction, the slip responds to the surplus of carbon much like a shino glaze with an orange blush.
