Been a Spring here in Ohio and feels like I am a month behind or more. I have managed a few tests and working diligently on clay bodies. Biggest epiphany of the winter has been clay bodies and glazes. Shocking! After changing clay bodies I found I lost many of my old "go to" glazes. This is something I don't see address too often. If I can catch up a bit maybe I can get a thread going. Best and keep testing everybody!!
Thanks! I now remember how to do this after reading your "how to normalize" post. I am going to do this and see if my assumption about the recipe (Val's Turquoise) is correct.
YES- it is the Otto Wenger recipe. I thought perhaps the picture was from one of your own tests which is why I asked about the opacifier... I'll do a test over the summer and see what happens.
OK so I went to the huge compendium of recipes from Alisa and found the Val Turquoise recipe just as she posted it. All I can think of is that it was adjusted proportionately to add up to 100% by the college before publishing. I used to remember how to do this but maybe John's glaze program will do it....
Alison and Claus Clausen posted their recipe for Val's Turquoise which differs from mine, percentage-wise. Their main list adds up to 77.5% and not 100% so I am wondering if something was left out or entered incorrectly. I see no way to contact them thru the post they left. My Val's Turquoise from the Central Carolina Community College is:
4.0% Dolomite
22% Gerstley
11% Whiting
27.6% Custer feldspar
21.3% Silica
ADD:
3.0% Copper Carb
2.0% Bentonite
I have made and used this glaze on several occasions - it is a gloss glaze with a good silica to alumina ratio making it extremely stable and durable.
I have a question about your matte turquoise glaze recipe which is similar to Pete's seafoam in content except for the fact that Pete's has titanium dioxide as a colorant with the copper carb.
I noticed that weathered bronze also has similar ingredients with titanium dioxide and the Juicy turquoise has tin oxide in it.
My question befiire i make a test batch of your glaze is does your recipe also have either titanium or tin in it as an opacifier?
Are there many potters on this forum with disabilities they need to work around? I was just thinking that I've talked to people with arthritis or paralysis and I know I've had to figure out other ways to do things. Although it isn't strictly about cone 6 firing, I just wondered if a group for potters to talk about their challenges with others who've overcome the challenges or found an alternative method might have some value in this forum. BTW I think this forum is amazing and love the direction it is going in. Huge Kudos to you for starting and running it!
Hi George and thanks for your comments in response to mine re 'an old recipe i have for a white matte glaze' and a possible replacement frit for a discontinued one. I will definately have a look at the suggested websites and thank you for the info. I had looked into a replacement frit some time ago and spoke to a couple of my nearest ceramics suppliers. The problem i found was that the replacement frit is not a commonly used frit in Australia (don't know why) so is alot more expensive, plus due to lack of demand, i would have to buy it in a large quantity. The original frit was Ferro Frit 4616 which i believe was then replaced by FF4103. It is expensive frit for me to buy compared to other materials. Both of these frits are high zinc bearing borosilicate frits.
My old recipe was this - from Janet DeBoos.
Ferro Frit 4616 60
Neph Syenite 20
Cresta BB 20
It is a super smooth white matt at Cone 6 which becomes shiny at Cone 7. It has excellent covering power and responds very well to oxide brushwork. Very stable and reliable indeed with no particular firing schedule. I had an electric kiln with a kiln sitter at that time. I used to fire to Cone 6 and let cool with bungs in til cold.
My thoughts are that i would rather try some other matt recipes that contain zinc to see if i can achieve something similar. I have found a few, so i will let you know how i go.
George, can I find out a little more about your firing schedules. I have tried the C. Harris Temmoku and with a standard cone6 firing schedule it's just a muddy brownish tan. Also, may be over applying the thickness of it. If you could share some firing schedule tips that would be great. You have beautiful work.
Am going on vacation Jan 20 - Feb 8. Will be in Hawaii and not thinking a whole lot about pottery. Will check in now and then on my iphone, but don't expect any long posts from me as the keyboard is about 2" x 1". Aloha!
Hi George - I just ordered some of the spanish red oxide from US Pigment, along with other oxides. Steven Hill mentioned the spanish red so i figure i will give it a go. If I don't get good results, I will definitely try the high purity next. He seemed to say to stay away from the others as it makes a big difference. I was trying to compare the Bailey's orange red cone 6 to the Steven Hill Bailey's red. Have you seen the book Bailey's cone 6 glazes? I was thinking of getting it but then I read that a lot of the ingredients are different from what is available in the US. Don't quite understand that comment but wondered if you had seen the book and if you found it helpful. I have MC6G and recently bought the accompanying software, so i have plenty to chew on for now anyway. Thanks again for your help/info. Really appreciate this website.
Hi George - I got notification of a comment regarding EPK vs. tile 6, but I did not find your comment online. My copies of recipes also only mention EPK and tile 6 specifically on 2 recipes, but several others call for kaolin. When they call for kaolin, what type do you use? Thx, MJ

Hopeful, you can give some comments and the ways for the improvements.
Hi George - Another question. The recipes I got at the Steven Hill workshop just say kaolin. Lakeside Pottery website specifies tile #6. I am buying EPK and hope to not have to buy tile #6 as well. Do you mix these with tile #6 or with EPK, and have you noticed any difference? BTW - do you fire using the Steven Hill firing schedule provided in the old cone 8 workshops, or have you fired these to cone 6? Thx again. MJ
George - just looked at your photos and they are wonderful. I especially love the glazing on numbers 55,56,58, and 59. I tend to use b-mix and I think at least some of these are on darker clays, but I would love to know what combos you used on these. They are just wonderful. Thx, MJ

Thanks for the advice George.
There certainly is lots to learn.
