I'm trying to get a grasp of slips ( puns always intended ).
There is a message in the archives from Vince Pitelka
( Feb 97) regarding ALL-TEMPERATURE WHITE BASE
SLIP. He says:
>If you are using slips for polychrome painting, these percentages
>may not give intense enough colors. In that case you can boost the
>opacifier in the base batch to 12%, and double or even triple the above
>oxide percentages. Keep in mind that such powerfully-tinted slips would
>only be appropriate for thin application, as in polychrome
slip-painting.
Is this then the definition of polychrome slip-painting -
powerfully-tinted slips appropriate for thin application ? If anyone would
care to share their experience I would appreciate it.
And if I ever figure out the difference between engobe and slip
I will again be able to sleep at night.

Correct me if I'm wrong,but here goes.An engobe is a slip. Slip is clay
with water added to it. The word engobe is used when you have formulated the
slip to fit any clay body at leather hard or bisqued stage-- it can also be
colored with stains or such.

According to Hamer's, slip is a "homogeneous mixture of clay and water"
and is used for "coating clays to give color and a smooth textured
surface."
According to Hamer's, engobe is a "term of wide meaning often
interchangeable with slip but including other materials." An engobe is
"used to cover a clay, produce a buffer layer, and give a different
surface, texture and color."
One of my mentors says that "slip is a mixture of clay and water ONLY,"
but an engobe has "a colorant other than clay added."
Of course, then there's "slip glaze," which again Hamer's says is "a
glaze that contains over 50% clay and is applied as a slip to the raw
ware." And don't even get started on Albany slip ... that's not from
Hamer's but from JL circa '96 when I began my own attempts to clarify
such terms. One of the key words is "interchangeable." Doesn't take long
to figure out that if I'm being oh, so precise, but those with whom I'm
communicating are operating in an "interchangeable" mode, somebody will
need to become more flexible. The only one I can control is me (and
that's on a good day) so it is I who gets dealt the flexibility card.
Good. I've had lots of practice.

In the Mojave trying to be patient waiting for the bisque to cool so I
can try a couple of new glazes ... going to finally mix that ^10 mottled
yellow, waiting since Jan. 9 (thank you, Greg!) Can't wait. Today is a
happy day.
