glazes that break well

Paul,
thanks for answering what I realize was probably a dumb question from
someone who doesn't quite know what she's up to with clay, yet! But while
I'm at it, you do tile, no? You probably know something about glazes that
break well over carving, yes? Well, could you suggest possibly a good basic
recipe that is not shiny/glossy that would break over carving, either low
or midfire range? Or where I might look for such recipes? I do have your
rasberry matt, is that one? It's funny because I keep saying I don't really
want to get into glazes at this point, would rather work with form, but I
seem also to be interested in surface texture, digging into the clay upon a
form.

Thanks,
Centa

Basically, but you would need more fluxes and less of the refractory
stuff like silica and kaolin. Also, some of the fluxes, like feldspar
and talc and barium carbonate wouldn't do you much good. You'd
probably be better off getting more frits.

get used to it centa...glaze [surface treatment] is a part of the process
and once you begin discussions on how do I get this effect or what type of
glaze should I use to get another effect your are already into glazes..We
could send off a heap of recipes to you but none would be of much use as
they fire differently in different kilns and temperatures...
frinstance here is a fovourite of mine

barium oxide 50
feldspar 50
kaolin 50

very dry surface and responds well to additions of
iron 1- 5
copper1-5
manganese1-5
glaze stains5-15 etc etc etc

dont use it on anyhting designed for food

I doubt it. I don't do any carving on my tile, so I don't pay much
attention to how much glazes break. It's going to be really hard to
find a glaze that breaks that isn't shiny. If it's fluid enough to
run a little, it pretty much has to be glossy. You could try
adjusting whatever glaze you have that comes closest to working, by
adding more flux, or by taking out some clay.

Here are two cone 5 oxidation glazes I know will break. The colorants
are only suggestions- try making them any color you want.

69 Green
Neph Sy 50
Whiting 20
Frit 3134 20
Ball Clay 10
Rutile 5
Copper Carb. 2

Wild Rose Temmoku (sometimes it's temmoku)
Lithium Carb. 10.5
Bone Ash 10.5
Neph Sy 61.5
EPK 17.5
Iron Ox. 10.5

By the way, where do you live? I do a lot of workshops, and I might
be coming close to you (Vancouver, BC, South Carolina, or Philadelphia
this fall). I always talk quite a bit about glazes in my workshops.

Have fun testing.
Paul

Ray--
Is this a cone 6 oxidation glaze? I love the surface that barium gives...

Ray,

I guess this is for cone 6 ox? Is it matt?
