MMB Posted October 16, 2014 Report Share Posted October 16, 2014 So being Im broke and trying to work with what I have Im going to try a few different avenues. I have a ton of Highwaters orange stone. I also have some local clay Im going to use as a slip, terra cotta color of course. So anyways I wanted to just utilize what I have and contrast a bit between the different tones of earthenware colors with some white and black accents. I have some Bringles all purpose slip that I mixed up a while back as my "white" inclusion. I recently picked up two 1/4 pound portions of Masons Best Black Stain and their Onyx Black Stain to trial run with. I was wondering has anyone used that slip recipe as a good base for stain inclusions? The recipe I used was: EPK 20OM 4 20 -or XX SaggarNeph syen 25Silica 30Gerst Bor 5Bentonite 2 +10% Mason stain I also considering using this as my clear glaze, considering it fits well in the end. Got it from digifire. I liked their remarks of its over all strength. Plainsman Cone 6 M370 neph sy 18.30 ferro frit 3134 25.40 epk 19.60 wollan 6.90 silica 37.60 talc 2.3 Just trying to find recipes that have what I have, sometimes it seems like a good choice then I realize Im missing the last ingredient. In my limited knowledge Im not sure if Ill have issues with the black stain slip. I know Ive had Amacos black underglaze go blue because of the cobalt. I thought of formulating a black slip because I have more Manganese Dioxide than anyone really should but I dont feel comfortable with the "dangers" and questions as to whether its food safe etc. Link to comment Share on other sites More sharing options...
bciskepottery Posted October 17, 2014 Report Share Posted October 17, 2014 I've used the Bringle slip, with oxides -- not stains -- for salt firing. The potter I salt fire with does use Mason stains in some of her Bringle slips. I've used Best Black (6600) with a white porcelain slip and it fires black. Both Best Black and Onyx have cobalt in them; Mason makes two blacks -- 6650 and 6666 that are cobalt-free. http://www.masoncolor.com/ceramic_RefGuide.asp Link to comment Share on other sites More sharing options...
