They describe them as "a great option for those who want the look of other clay bodies but don’t want to add another clay to their studio. Engobes can transform a red clay body into white or a white clay body into black". They claim it is possible to apply to wet clay, greenware or bisque, and fire from cones 5-10. Also sold by other suppliers (who do not identify them as Mayco on pages).

Why your supplier does not sell dipping engobes:
#1 Getting the thixotropy just right is hard.

Two things are happening simultaneously: The engobe is gelling and last few drips are falling away. I am rolling the mug just enough to encourage them (but so so much as to disrupt the gelling). Engobes are best applied to leather-hard ware and thus need to be thixotropic. The dipping process for each is to stir, pour-fill the mug, pour it out and push it upside down into the engobe. If I finish before the 10 second gel-time is up I get a perfectly even layer that does not move. Achieving this behaviour requires careful additions of Epsom salts. As the slip approaches the 10-second threshold even a slight bit more salts will turn it into a bucket of jelly (if that happens I add a drop or two of Darvan). This process works across a range of specific gravities (about 1.45-1.6), the higher the SG the trickier it is (but the faster it dries). I work at the low end, it’s easier..
Are dipping engobes useful? Incredibly. But the technical support that would be required to help customers learn the careful tuning of rheology is not something that any commercial glaze supplier would be prepared to do. No problem. DIY is the answer. This engobe is L3954B.

Engobe
Engobes are high-clay slurries that are applied to leather hard or dry ceramics. They fire opaque and are used for functional or decorative purposes. They are formulated to match the firing shrinkage and thermal expansion of the body. |
