George your nutmeg must be different from the one I am using.  Try Richard Bursh nutmeg.  I use a variation, but it is about the same as Richard's.

George, once again - thanks for the pointers.  In the spirit of Christmas, I am making a list of ingredients I need and checking it twice.  I am afraid I have to be my own Santa though.  Cheers and happy holidays. 

(BTW - I think you follow clayart.  John Britt posted a recipe for Bailey's red/orange for use at cone 6 oxidation.  It is a bit different from the one given by Steven Hill at the workshop.  Did you happen to see it?  If not, I can forward it to you.  Obviously I have not had the chance to test it.) 

Hi George - posted on Clayart Dec. 6 by John Britt under a discussion on Iron Reds.  He lists it as cone 6 electric. 

G-200 feldspar  46.7

EPK                     4.0

Bone Ash            15.0

Talc                      16.9

Silica                     11.4

Lithium Carb         4.0

Bentonite               2.0

Red Iron Oxide       11.5

Please let me know your thoughts as to differences between this and the Steven Hill recipe.

Question - when I put the recipe in glazemaster, it adds to 100 with the bentonite.  Does bentonite usually go above or below the line in a glaze formula?  Makes no difference but just curious which is common.   cheers, MJ

I'm very happy to recognize you ~  

Your glaze are so amazing! I like it! 

I think that i will upload some picture at later stage.

Hopeful, you can give some comments and the ways for the improvements. 

And lastly ,my English is poor. Apologizes.

Have a nice day~

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.

Thanks again :)

Hey George,

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?

Barbara

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.

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.

Thanks George, I have the book and I will look it up... I appreciate the help.

Morning George! 

Wow!  Thank you! 

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 for the advice George.

There certainly is lots to learn. 

George, is there a place where we can just post recipes with notes, even if we haven't tested them or have a photo?

I never made it to the studio today because I thought I'd better check some of the recipes for safety, limits etc, and I got involved in back engineering some of them like 2D which have been mentioned here, and I saw that some were no where near the cone 6 limits for silica, and too high in other oxides for cone 6, so I redesigned a few of them like 2D, etc.I came up with my own Strontium Crystal which has a bit better expansion than the original, and has a bit of zinc ox, as had one version I have, One almost mentioned 8 % yellow iron for orange. I don't know if that was for reduction or ox; but I will test it.

That Pier black is a really unsafe glaze. A better choice would be Val Cushings' satin black. I've tested it at cone 10 and it's a beautiful glaze and I think it would work at cone 6 and be much safer than Piers Black which has chrome which is a known carcinogenic, as well as a large amount of cobalt. I'm not adverse to chrome when nothing else will do, but it's really not necessary in this case.

It would be great to have have a list of glazes with firing notes, etc. without discussion, so the list wouldn't get too cluttered. We could discuss them another forum on this site.

I also found a Persimmon  on lines and can post that as well, since someone mentioned looking for a persimmon glaze.

Looking at my S. Hill notes I see he has used a high magnesia glaze, so I came up with my own version of one using a sodaspar which should make it work at cone 6-8.

I'll be batching and testing these but it will take me a couple of weeks to get them all weighed out, sieved, on to tiles and fired; but I'll try to get a few done in the next few days just to test in my small electric kiln.

Till later,

June

Are you familiar with GlazeMixer. Not sure if you would be recreating the wheel. Might use their database as a base. They have a big database of private and shares formulas. glazemixer.com

Love the warm colors on the mugs.  Which did you use? 

HI I'm a new member of this site. I do tile and I fire at cone 6. I am confussed about the cone 6 data base and testing. Is there a group of people testing each glaze and posting their results, or do we just send in what we are doing to share it with others. Is there some type of protocal to follow? I would like to contribute if possible although my glazes are nothing like what you are pulling out of your kiln. I'm very inpressed. I was trained with cone 10 reduction and had about given up throwing becouse I thought it was not possibe to get the look you are getting. fill me in on how this data base works.  please Kabe

Thank You George for your comments on the wine lushes! Love making these forms...the challenge for me is to create a flowing form from two separate pieces. My love of wine seems to be helping :)

Thanks John will Google them, it would be lovley to see some studios while I,m away and although photos are great its always great to see others work in the flesh, so to speak.

Cheers Rose

OOPS! Sorry George I wrote 'John' by mistake, I've just had a look at the potters you listed and only one of them is In Auckland but may be on to something with A chap from Hawks Bay, as I'm origanaly from there and may be doing a quick drive by.Cheers Rose

Hi George,

Registered for Insight live, but don't know my user id or password. Please help. Will entering the group provide access to Insight live or do I have to download the software?

Hi, George. Yes, living on an island can have its disadvantages - the cost of shipping is horrendous. I noticed you've been experimenting w/SH cone 6 glazes in oxidation. Me too! I attended two of SH workshops - 2005, 2008. Looking forward to collaborating w/other potters via cone6pots network. Thank you for contacting me.

Beth

P.S. I was born in Lansing!

Hi George, Tom Waggle, Donna Ferrara and myself started out by making comments/questioning glazing and have ended up having a discussion re achieving the look of "Wood/Salt" fired pots at Cone 6. I thought perhaps we could post this as a discussion topic? If so, could you copy these conversations etc across to a discussion page please. It might be of interest to other members but may not been seen where the comments are at present.  There are other relevant comments posted on todays 'Latest Activity' page.

Thanks Jan

thank you, time to start mixing glazes  :-)

Thanks George. Very busy teaching a full load at a college and making pottery. Already participating in a crystalline glaze forum. I've been doing crystalline glazes for several years at cone 6. Just had an article about my process published in Clay Times:

Congrats on your switch to full time potter George.  This site has grown and made terrific changes over the past 3-4(?) years since I first joined and I'm excited to see where you'll take it when you aren't spending 40 hrs a week in a corporation!

Hi George, I'm interested in the Insight Live User-Group.  Would you please send me some instructions on how to join? 

I just came from the dermatologist and received a shot to stop the dermititus on my hands.  Seems to be coming from something related to the pottery.  Would appreciate hearing from other potters on how they handle this type of situation.  How about gloves?  What kind do they use?  I'm hoping it's just the glazing where I am forced to wear the gloves, but just am not sure at this point.  Can't give up the pottery though.

I love this website....it's my absolute favorite!

I like Potters Beat Disability better than the title I had George!

George, 

I just joined last week and I put a check in the mail to you today,  I hope that is fast enough.  Thank you for creating this great potters resource!  I love it.

Nadine Mercader

I thought we already friends!

That should be "were/are"

Thank you George,  I figure that when one finds such an excellent resource than it is a responsibility to suppport it fully.  

I hope that you are feelign better.  I am desperate to get an answer to my spray glaze question.  If you see this would you mind sending me an answer.

Nadine

Good topic. Please reply to the new discussion http://cone6pots.ning.com/forum/topics/glazing-the-foot-from-joanna...
