In Topic: Fake Horsehair Raku

26 July 2015 - 04:24 PM

this may sound stupid but there is a potter, mckenzie smith, in florida who covers an area of a raw pot with wax, draws through the wax into the clay and fills the tiny, thin line with black glaze. these lines are hair thin. firing once to remove the wax leaves the pot clean to accept the clear glaze.

could this work for you? wiggly lines could look like horsehair.

Brian Persha use to draw on his pots using that technique back in he 1970. He had a studio in Red Lodge, Montana.
it is a very interesting and precise technique.

on pg 109-110 of Ash Glazes by Robert Tichane, a technique is described to collect rinse water from ash. The soln would contain potassium carbonate, NaCl and trace amounts of potassium phosphate and sulfate.

If a ware were sprayed with a light coat of this solution, then fired to cone 8, it would have a light varnished effect with a slightly glossy surface.

With that in mind, I propose to modify what oldlady and marcia suggested.

1. Spray the outside of bone dry ware with ash rinse solution, as above.
2. Apply wax over the spray.
3. Draw lines, feather design as desired.
4. Apply mason stain, underglaze, or oxides into the etched areas. Wipe off the extra.
5. Glaze the inside of the ware with a food safe liner.
6. Slow single fire to vetrification.

The resulting ware should have varnished surface, black design from the etching, and a food safe interior.


I have not done this before. It might just work.

Any thoughts?

With my luck, if I made a clay statue or something, it would explode.  If i made it out of straw it might be safe.

1. Accidental happenstance always seem to look better than engineered intention.

2.  demands and deadlines propotionally  increase ware distruction and disasters.

 

 

As to the austalian abbreviations, following Earthfan's examples....would pottery experts be potties?

Thank you for the links to your suppiers.  I have used big ceramic store in the past with great success.   St George, Utah is a small town and the local supplier just changed ownership. So there are a few hickups in transition.  Raw materials were part of that hickup.... There are only a few of us who make our own glazes around here, so the raw materials were put on the back shelf during the transition.   .BUT they do have EPK... TJR.

 

 

SO from the responses, I get the feeling that there is no great substitution for Strontium.... I guess i will have to wait for the supply truck.
