I'm currently glazing some stoneware pots to go in the wood fired kiln, and I have found a few that I glazed a year ago, but never got round to firing, that will go in this kiln load too.... trouble is, after all this time, I really don't know what some of the glazes will be, so the firing will have some surprises!<br />Glad that you are having some good results with RTM, and it is interesting to use such glazes under others. It has been a long time since I really updated the blog, but I am hoping to post more regularly again, and may even get round to adding a few more glazes to the high fired glaze page at some point. Unfortunately I'm not sure how to contact the Welsh "spontaneous glaze splasher", but you never know, you may meet up one day... <br />Do let me know how you get on with the glazing.Peterhttps://www.blogger.com/profile/03078608554226394069noreply@blogger.comtag:blogger.com,1999:blog-3580639918656230427.post-36034073925081365372022-09-21T06:16:49.459+12:002022-09-21T06:16:49.459+12:00I would love to contact the potter in Mid Wales as...I would love to contact the potter in Mid Wales as I am also a chaotic glazer who loves your posts Peter.

Wales doesn't seem so far away really, I still remember some lovely family holidays that we had in Wales when I was a child (many, many years ago!!), and it is a magical place. I do know that you have some very fine potters in Wales. I have been meaning for ages to put another blog post together, and you never know.... you may have inspired me to dust down my keyboard!

I also hope that your health held up after the mad rush to get everything ready.<br /><br />I was also wanting to ask whether you had a chun-type glaze which fired in oxidation at 1280ish, but after a trawl through your glaze posts I found the Emanuel Cooper, which looks perfect. <br /><br />What struck me yet again was your generosity and patience - often repeating the recipe for the same glaze lower in the comments, giving everyone individual attention. I award you the badge of Beeskneesness!

The firing for this glaze combination was usually cone 9 to cone 10 in oxidation in an electric kiln. This works best on a buff stoneware body that contains some iron. A white stoneware is never as successful.<br /> <br />I don't know if you are writing from New Zealand or another country, but the stoneware body that I generally use is Southstone from Southern Clays in Dunedin NZ, but I sometimes add a quantity of brick red earthenware clay to give it a better colour when fired in oxidation and to drop its maturing temperature. Southstone on its own really wants cone 11 in reduction to be vitrified and water tight.<br />Peterhttps://www.blogger.com/profile/03078608554226394069noreply@blogger.comtag:blogger.com,1999:blog-3580639918656230427.post-80076873642545221712016-12-06T04:07:36.281+13:002016-12-06T04:07:36.281+13:00hi there i absolutely love this glaze , could you ...hi there i absolutely love this glaze , could you please tell me what firing temps its for please and which clay body you used ?

Normal cool down in my electric kiln ha...Hi Daniel,<br />Normal cool down in my electric kiln has been fine for chun. Glaze thickness is an interesting one.... The chun really has to be applied over another glaze, such as a tenmoku for it to give a good blue. I first apply the tenmoku, and have the chun ready and waiting to apply as soon as the tenmoku is just about touch dry (no shiny bits anywhere). Then I quickly apply the chun by pouring it. The timing of this is important, if the tenmoku is too dry it may blister and pop off the pot, and if it is too wet it won't accept the chun. You will find it fairly easy to apply if you pour quickly and don't fuss with it. If you go back over an area it may well blister and start to lift off the tenmoku glaze. <br /><br />You may find that the chun cracks a lot as it dries over the tenmoku, or even starts to lift in places. Usually this is not harmful and it will heal when fired, but if it is lifting badly I dampen the edge of the lifting part with a small wet brush, and it will sit down again!<br /><br />I guess that the chun could also be applied by spraying, and this might make the application easier?.. but I haven't tried this myself!<br /><br />Try on something that doesn't matter, glaze application is a bit of a conjuring trick, and needs practice!<br /><br />Best Wishes, P<br />Peterhttps://www.blogger.com/profile/03078608554226394069noreply@blogger.comtag:blogger.com,1999:blog-3580639918656230427.post-32070799687807563852016-05-04T05:19:36.741+12:002016-05-04T05:19:36.741+12:00That's really useful thank you!

It is worth experimenting with clay bo...Hi Daniel, <br />It is worth experimenting with clay body. There is nothing "wrong" with white stoneware, or with stoneware with a higher iron content, but the two make possible different things. I like some of my cobalt blue glazes better on a low iron stoneware, but appreciate the extra complexity that a higher iron body will give to my green glazes. When it comes to chun, you are most likely to get them to work on a body that has some iron in it. <br /><br />I sometimes mix a brick red earthenware clay into my stoneware clay for when I fire in the electric kiln. The brick red clay lowers the maturing temperature of my high fired stoneware body, and also gives the clay a warmer "toasty" look. <br /><br />I have experimented with the chun over other glazes, and it is certainly worth experimenting. When firing in my wood fired kiln I have used chun over copper red and shino glazes with some success.<br /><br />If you are firing to cone 9 you will probably find the Black Tenmoku glaze that I have here a bit under done, but the Red Tenmoku recipe that is on my High Fire Glaze page should work OK (the "red" gives a dark tenmoku brown with an iron red "break" where thin over some clays).<br />Red Tenmoku cone 9-10<br /><br />Potash Feldspar 50<br />China Clay 10<br />Whiting 5<br />Dolomite 15<br />Silica 30<br />Red Iron Oxide 8<br /><br />Good Luck!

I am actually in the process of changing from earthenware to stoneware and plan to fire >cone 9. I haven't decided on a clay body as of yet. Will a higher iron content clay make a difference in oxidation? Do you think I should stay clear of a white stoneware body for the sake of glaze interest?<br /><br />Also, have you had any interesting variation in the chun colour over a different glaze? Reading about oil spot effects using high iron content made me wonder: has any one managed to get that effect and the blue from the chun? Perhaps the micro bubbles necessary for the blue chun and the bubbling that causes the oil spots are incompatible. Just thinking out loud.<br /><br />Thanks again<br /><br />DanielDamielnoreply@blogger.comtag:blogger.com,1999:blog-3580639918656230427.post-23315064580493460742016-04-28T09:27:30.807+12:002016-04-28T09:27:30.807+12:00Hi Daniel,
The bowls in the photo were fired in my...Hi Daniel,<br />The bowls in the photo were fired in my electric kiln in oxidation, and the black tenmoku is usually fired in my electric kiln as well, and can give a good very dark brown-black colour. To get the best black it is important to fire from cones 8 to 10 slowly, this glaze likes heat and time!<br /><br />The blue chun can be fired slightly lower, it should work from cone 9 upward. I used to have a lot of success with the chun, and then couldn't get it to work at all for a couple of years. The problem I think was caused by a particular batch of zinc oxide that I was using, and unfortunately I had bought a 25 KG bag of it which took me a long time to use up! Now that it is gone, I am able to get the blue working again! Glazes can be tricky, particularly those that rely on layering one glaze over another. Don't give up if you find things don't work as expected the first time!<br /><br />Do use cones when you fire, they are really the only way to accurately compare one firing with another. <br /><br />Best Wishes, PPeterhttps://www.blogger.com/profile/03078608554226394069noreply@blogger.comtag:blogger.com,1999:blog-3580639918656230427.post-3678143223602291682016-04-28T01:15:00.202+12:002016-04-28T01:15:00.202+12:00Hi,

I am firing in an electric kiln and note you said:<br /><br />"I find this gives a good blue chun when used over an iron bearing slip or a tenmoko type glaze. Reduction is not needed for this glaze, and I have good results in an electric kiln. It does seem important in oxidation to use an iron bearing slip or glaze under the chun for the best results."<br /><br />When you say you have had good results in oxidation do you mean you have had results similar to the bowls pictured above?<br /><br />Also what should I expect to get from the tenmoku recipe you gave above? Will I be able to get the black in oxidation?<br /><br />Thanks again,<br /><br />DanielDanielnoreply@blogger.com
