Tom Posted July 4, 2012 Report Share Posted July 4, 2012 Hi All I have seen a few pieces for a local artist that were amazing. The artist said they used "self reducing glazes" but didn't give anymore information. Looking on line many people talk about them and don't say how they did just the "you should try this" or how bad it went. Is there is anyone out there that is willing to share with the rest of a good starting recipe. Thanks for all your help with all the past threads.

Marcia Selsor Posted July 4, 2012 Report Share Posted July 4, 2012 A very long time ago (early 1970s) I used silicon carbide fine mesh to reduce locally in a oxidation fired copper red. It was a very dark red but red. Marcia Link to comment Share on other sites More sharing options...
ratdog Posted August 6, 2012 Report Share Posted August 6, 2012 A very long time ago (early 1970s) I used silicon carbide fine mesh to reduce locally in a oxidation fired copper red. It was a very dark red but red. Marcia i too would like to know more as it applys to gold chloride and if carbide would locally reduce it to a sheen. i read a bit on this but need more info. and i have seen the blood reds before ....nice stuff.

Jan Anton Gilles Posted August 9, 2012 Report Share Posted August 9, 2012 I don't think it is impossible to reduce the most of glazes , even if it contains a very strong reducing agent , it is simply chemistry,in soms rare cases like this red glaze , wit carbide , attention must be because carbide maybe explosive !

neilestrick Posted August 9, 2012 Report Share Posted August 9, 2012 There's been some talk of this on the ClayArt forum recently, getting copper reds in an electric kiln with the addition of silicon carbide to create localized reduction. Nobody that I know of has been able to get this to work as well as actually firing in reduction. Probably would work better in other glazes. It must be a super fine mesh size of silcar or you just get bubbling. Test, test, test..... Link to comment Share on other sites More sharing options...

Guest JBaymore Posted August 9, 2012 Report Share Posted August 9, 2012 Yes, it has to be a very, very fine silicon carbide. Explosive! No. See the firefighting section: http://www.washingtonmills.com/documents/msds/# best, ..............john Link to comment Share on other sites More sharing options...

Test, test, test..... as I said A llong time ago (early 1970s) I used silicon carbide fine mesh to reduce locally in a oxidation fired copper red. It was a very dark red but red? I think the amount of silicon carbide was a small fraction of one per cent..testing is really necessary as always. Marcia Link to comment Share on other sites More sharing options...
JLowes Posted August 10, 2012 Report Share Posted August 10, 2012 Coyote Clay and Color has a couple of Cone 6 Copper Red glazes out that use this technique. Perusing their website could give you an idea of what you may expect. But you have seen examples of what you want, so this may be moot. Of course you may not be after copper red either. http://coyoteclay.com/ down the page some are two pots John Link to comment Share on other sites More sharing options...
Marcia Selsor Posted August 12, 2012 Report Share Posted August 12, 2012 the "Plum" one is closer to what I was getting. they are some very nice looking commercial glazes. Marcia Link to comment Share on other sites More sharing options...
