porous mat white slip/glaze?

[kokopelle2012]

I am working with Terracotta, making plant pots, and have a black iron oxide i've worked into a slip for creating black decoration on the unfired pots. i would like to do the same with white. My concern is that using a glaze essentially seals the clay, where what i'm hoping to do is color the clay without sealing it.

Does anyone know techniques or products for this? What i found that i thought might work was a white mason stain mixed with a light body clay slip?

any advice is appreciated.

Ive had good luck with the laguna engobes..

 

 

 

ENGOBES

These clay coloring slips allow for the creation of hue with a dry, earthen texture when

applied to greenware. Fired to Cone 5 they become vitreous. Ideal for accentuating the

natural color of the clay and for adding decorative accents. These engobes do not contain

lead and are safe for food and beverage containers when properly fired. Available in liquid

and pints only.
