Val Posted May 7, 2016 Report Share Posted May 7, 2016 I've been hunting for a cone 5/6 or even a cone 06 turquoise that is fairly opaque, satin or shiny ,and food safe. Everything I have found is either transparent, or too green, or not food safe etc. Recipe or ready made is fine The photo shown is PERFECT, but a secret. Thanks !

oldlady Posted May 8, 2016 Report Share Posted May 8, 2016 how about this? Link to comment Share on other sites More sharing options...
glazenerd Posted May 8, 2016 Report Share Posted May 8, 2016 Maybe this? Marcia: I would be tempted to us FHC as the ball clay in the recipe- would deepen the color. Nerd No copper carb.. in this glaze. Link to comment Share on other sites More sharing options...
Marcia Selsor Posted May 8, 2016 Report Share Posted May 8, 2016 former coop studio sign used a turquoise. they can be very sensitive to thickness and cooling cycle. Link to comment Share on other sites More sharing options...
Val Posted May 8, 2016 Author Report Share Posted May 8, 2016 Hi Marcia and " Old Lady", First, Old lady ( that seems a little disrespectful but could not find your name ) do you have a recipe for the glaze in your photo? and Marcia, is the glaze on your vase photo the glaze in the recipe you posted ? Thank you so much for all the help ! Val Link to comment Share on other sites More sharing options...

oldlady Posted May 8, 2016 Report Share Posted May 8, 2016 the recipe is from Bill vanGilder's book, "Wheel thrown pottery". it is called Rutile Green. i use the base recipe and add 5% cerulean blue, a color from Mason stains which is no longer made by them but they can tell you how to combine two of their colors to get it. or use turquoise stain and get a different color. i have tested this base glaze with many different color stains and most of them come out great. original recipe calls for copper carb, obviously you will not add that if you want a different color, just the base plus bentonite and rutile. here it is straight out of the book. rutile green glaze, cone 6 oxidation talc..........................................5 custer feldspar........................22 whiting.....................................4 silica........................................26 tile #6 or EPK..........................17........i use EPK ferro frit #3134........................26 100 add bentonite.................................2 powdered rutile.......................6 copper carb............................4 have fun with it, the glaze as written is a yellowish green that i do not like. it was used to go over other colors and modify them. used alone with other colorants you have a nice, easy glaze.
