TJR Posted April 24, 2015 Report Share Posted April 24, 2015 I have a 5 gallon bucket of Goldart sitting in my studio. I used to use it for white slip; Ball clay 33% EPK. 33% Goldart 33% Called Schiller White Slip. Not using slips any more as my glazes are very opaque. I got a glaze recipe; [Cone 10 reduction] Ash 50% Goldart 50% But it is very dry. A nice yellow ochre colour though. Any thoughts? TJR. Link to comment Share on other sites More sharing options...
neilestrick Posted April 24, 2015 Report Share Posted April 24, 2015 It's way too high in clay to melt out for a proper glaze. I would try adding some feldspar to the mix. Link to comment Share on other sites More sharing options...
TJR Posted April 24, 2015 Author Report Share Posted April 24, 2015 Here in lies the problem. I substituted Goldart for EPK in an ash glaze that I have. It came out a boring whitey/cleary. I think it was; Custer 40 Goldart 30 Ash 30. Of course I am testing before I put it on any pots. I know that Goldart is a white stoneware clay. TJR.

Marcia Selsor Posted April 24, 2015 Report Share Posted April 24, 2015 I forgot to search for that one I mentioned from 1969. I have several old glaze notebooks- 3 ring binders. I was looking for something yesterday and thinking how the old papers were yellowed and the purple dittoes were really faded! Marcia Link to comment Share on other sites More sharing options...
rayaldridge Posted April 24, 2015 Report Share Posted April 24, 2015 Is the ash in the recipe washed? I ask because I've seen half and half clay and ash recipes that melted well, but if the ash is washed, a lot of flux goes with the wash water.

Callie Beller Diesel Posted April 24, 2015 Report Share Posted April 24, 2015 Sub it in for some of the clay in a shino. I've had some good luck playing with that. Link to comment Share on other sites More sharing options...
Tyler Miller Posted April 24, 2015 Report Share Posted April 24, 2015 It wouldn't be the worst in a celadon. Not quite enough iron to colour it by itself, but if you had another iron contaminated material, you could maybe get a natural celadon going.

One scoop this, one scoop that. How big were the scoops? Link to comment Share on other sites More sharing options...
Mark C. Posted April 25, 2015 Report Share Posted April 25, 2015 TJR-I have a bag of goldart with your name in it as I never used it-stop by on your next trip to see the redwoods? I think scoop glazes are just for us old timers.Scoop size does not matter as long as they are all the same scoop used. Mark Link to comment Share on other sites More sharing options...

Maybe you hit the nail on the head. TJR. Thanks. Link to comment Share on other sites More sharing options...

Marcia Thanks, Marcia; Here's the problem. You have to convert scoops to grams as I am assuming that the colourants are a percentage of 100 grams and not a scoop. Right? Tom.

TJR Posted April 25, 2015 Author Report Share Posted April 25, 2015 Conversion is not a big problem as I work in grams anyway. Thanks for doing this, Marcia. T. Link to comment Share on other sites More sharing options...
Marcia Selsor Posted April 25, 2015 Report Share Posted April 25, 2015 you could weigh the final amount of the base and add the percentages. Not too difficult. Marcia Link to comment Share on other sites More sharing options...
