Tom - in all my readings I have never had the difference between those =

be the way to handle them ... would they need to be only dipped, poured, =
brushed? Thanks again....Carly

Not all slip glazes will have a glossy finish. A glaze that was used
at Utah State University consisted of a local clay with 10%
Zircopax added. The resulting cone 10 glaze was a matt yellow
green. They called it Hyrum Dam (after the clay location).

Don Hoskisson says his slip-glaze turns out to be matt, not glossy as is
the common finding. Yet, by adding the 10% Zircopax, you have converted a
simple slip glaze (by defintion clay only) into a "regular" glaze, no
longer definable as a slip glaze. Sure, this is nit-picking but I am
trying to lessen the confusions.

My copy of Hamer's Dictionary defines slip-glaze, thus -
<< Vitrifying slip. A glaze that contains over 50 percent of clay and is
applied as a slip to the raw ware>>.

I welcome the "nit-picking" by Tom. The addition
of Zircopax may well move the mix to the glaze side
of the definition. I dug a slip near the Hyrum Dam
slip location. I fired it on many pieces without additions.
It fired to a more apple green matt--not the yellow
green of the Hyrum Dam Glaze. Tom will this qualify
as a matt slip glaze?
