jennifermulligan Posted September 2, 2013 Report Share Posted September 2, 2013 I am looking for a white glaze that will blend well with a darker glaze, so that I can glaze 2/3 white and 2/3 dark, with middle section white over dark. I have some nice darks--red, purple, black, blue--but I'm glazing hundreds of plates and need that 1/3 plate division glaze pattern with one section white. thanks.

bciskepottery Posted September 3, 2013 Report Share Posted September 3, 2013 What temperature are you firing to . . . Cone 6, Cone 10; also, in oxidation or reduction atmosphere, and electric or gas/fuel kiln? Are you mixing your own glazes or looking for a commercial product?

Biglou13 Posted September 3, 2013 Report Share Posted September 3, 2013 What kind of clay?What color of clay fired?Glaze application; dipped? painted? sprayed?Gloss?semi gloss ? Matte?Functional? Non functional?Food safe (ish)? Food safe (tested)?Are you making plates? Commercial bisqueware?Translucent? Opaque?What is purpose of project?Why are you glazing hundreds of plates?Do you have pictures?Have you tested anything yet?Is there a project deadline?How are you? What's your shoe size? Do you have pictures in your gallery? Is your profile filled out? Is this part of your job with non profit?Did I get to 20 questions?Yes the above questions are PARTLY sarcastic. The more information you give, the more we know about you, your project, the more likely, and better advice you'll get. 20 questions is better than answering a vague question with a vague answer?If it is for non profit/good cause you'll even get mo' better help.Solution options....Start with a good KNOWN, base glaze, (which hopefully fits body) which takes color ants well. Using same base glaze may make it easier. one ive recently heard of is ravenscrag. not as cheap as 100%scratch but looks promising and would be interested in opinions on this glaze Link to comment Share on other sites More sharing options...
jennifermulligan Posted September 3, 2013 Author Report Share Posted September 3, 2013 OK...I really do know better...but I'm specifically looking for a glaze called "NK white" and was hoping someone would throw out the recipe in response to my plea--because it blends so well with dark glazes. Since no one seems to have heard of NK white, let me give you the relevant info: I am working for the Roanoke Rescue Mission In Roanoke, VA, running the pottery studio for the 18 month residential rehab treatment program. One of our projects is to provide 150 soup bowls for a "souper bowl" fundraiser in January. Therefore, I m looking for a functional, food safe glaze. I am firing with standard clay #153 (light tan) to ^6 oxidation. I inherited a bucket of NK white which is great--a soft gloss that feathers the dark clay it covers--almost like a temouka. In the past I've used different types of white--from glossy to matte, and in-between. But none really interacted with the dark glazes. I am hoping someone has had success with a white that really melts into the dark glazes underneath, not just covers them. Oh...and I I wear a size 7 shoe. Anything else? thanks so much for the help!!! sending smiles--Jennifer Link to comment Share on other sites More sharing options...
bciskepottery Posted September 4, 2013 Report Share Posted September 4, 2013 This might work for you . . . Antique White (Cone 6, oxidation) Nepheline Syenite, 41.7% Silica, 16.7% Gerstley Borate, 25% (can sub Gillespie Borate) EPK, 8.3% Whiting, 8.3% Total, 100% Plus Bentonite, 2.2% Tin Oxide, 8.3% Red Iron Oxide, 0.9% Here is a platter with Antique White over Licorice. The Licorice had a thicker application than usual, but you can see how the overlap works. The claybody is Standard 266. Link to comment Share on other sites More sharing options...
Biglou13 Posted September 4, 2013 Report Share Posted September 4, 2013 oh size 7 that explains everything! (lol) bcisk... knows his stuff.... i love 266 but its a "special" child at for me it tend to do things with glazes that no other clay does. but a good white recipe is golden. try tweaking application process. dip half let dry. dip other half and let run. food safe" is anther issue...... i'd go with a commerically made "bag" glaze that has been tested "food safe" unless you have a library of glaze ingredients already. it will be time consuming and probably not cost effective to make and test your own? good on ya for working for good cause. there are some factory reps here, from glaze companies, that i hope will step up and come to your socially redeemable, non profit, rescue. (clearing throat LOUDLY) another solution (if your married to your clay) is iron wash, or other dark colored wash, plate then coat only half with white, the clear over that. ill try and get u recipe from group studio, white recipe it one of those miracle glazes that works on all bodies. and it blends as u like. what is your dark glaze maybe that is problem Link to comment Share on other sites More sharing options...
bciskepottery Posted September 4, 2013 Report Share Posted September 4, 2013 Biglou13 . . . Antique White is a durable glaze; have used it for going on six years as both a liner glaze and for exteriors -- cups, bowls, platters, etc. It is a soft white, unlike some zircopax-based and other whites that tend to be more "refrigerator white" and bright white. The touch of red iron oxide softens the tin oxide nicely. None of the ingredients are on the nasty list for leeching, e.g., copper carbonate, barium, etc. The amount of tin oxide does make this glaze a tad expensive -- but still less expensive than a commercial in either wet or powder form. And, the Gerstley will give it a spongy consistency. And, yes, its pink in the bucket. Link to comment Share on other sites More sharing options...
Biglou13 Posted September 4, 2013 Report Share Posted September 4, 2013 There you go Jen A well tested white glaze. Funny I just bisqued my first clay and it Is pink. Also. I've saved this recipe for later. Does it play well with different clays? Link to comment Share on other sites More sharing options...
oldlady Posted September 4, 2013 Report Share Posted September 4, 2013 jennifer, the Empty Bowl events held in many parts of the usa is usually supported by many potters, not just one. do you have access to a group of potters, maybe through a supplier in the area? do you have time to put a story in the local paper asking for help? our guild supports the womens shelter in winchester va and we each give 20 bowls. maybe you could arrange something with a pottery school in the area and take student work. that is done in lots of places. check out EMPTY BOWL online for history of it. it is admirable that you are taking on all this but it might be easier if you ask for help and get others involved. good luck.

jennifermulligan Posted September 4, 2013 Author Report Share Posted September 4, 2013 First--thanks to "oldlady" for calling and giving me a recipe. I appreciate the info. And I'm checking out the other recipes. I do have a BIG closet full of chemicals, so I've got lots of options. I did want to clarify one misunderstanding--When I said I was responsible for making 150 bowls for our souper bowl fundraiser, I didn't mean to convey that I was the only one contributing. The Blue Ridge Potters Guild provides 500 bowls for our event, then another 200 for an empty bowls fundraiser in Floyd County, VA. I myself made 56 bowls last year for the rescue mission and 25 for Floyd County. Our 150 commitment this year is because of my new job at the Roanoke Rescue Mission--instead of my making 50+, me and my students are going to make 150. And then the other local potters are committed to providing all the rest--what a great group!!! thanks again for all your help. sending smiles--Jennifer Link to comment Share on other sites More sharing options...
