clay lover Posted April 22, 2012 Report Share Posted April 22, 2012 I am looking for a dependable base glaze, cone 6, that has a satin surface, nice to handle and food safe. I came across Val Cushing 71 in a book, but don't remember where I found it. Do any of you use this and do you have a good satin base that is receptive to oxides, that I might try? I have looked up and mixed a lot of other glazes, but this is my first time to start with a base and add colorants to get what I want. Custer spar 40 frit 3124 9 whiting 16 talc 9 epk 10 flint 16 Thanks, all. Link to comment Share on other sites More sharing options...
Marcia Selsor Posted April 22, 2012 Report Share Posted April 22, 2012 This is a nice satin gloss clear that works well with stains at ^6. Hotter and it goes glossy. Sue Hintz Clear 6^ reworked by Ron Roy back in late 90s. Cornwall Stone 33.5 G200 22 Whiting 18 Gerstley Borate 10 EPKaolin 5.5 Silica 11 Bentonite 2 Marcia Link to comment Share on other sites More sharing options...

clay lover Posted April 23, 2012 Author Report Share Posted April 23, 2012 JD, pics look good. What does it FEEL like? The little test of VC 71 I've done with no colorants is silky, makes you want to touch it, and a bit translucent, but that might be from the lacl of colorants/ Maybe?

Colorants rarely affect the glaze' texture. If you like your base glaze - just start to perform some tests using different colorants / quantities. Enjoy!

Aodenkou Posted September 29, 2014 Report Share Posted September 29, 2014 I was going to try VC71 and I put it into an Excel worksheet so I could get different batch sizes and noticed that it totals 91 not 100. Does anyone know if this is correct at written or are there ingredients missing? If so could you please share? Thanks in advance! Link to comment Share on other sites More sharing options...
Biglou13 Posted September 29, 2014 Report Share Posted September 29, 2014 I have tests of VC 71 waiting to dry..... I have 3 variants with colorants waiting to fire. ....... Duh I did not test base glaze without colorants....... It adds up to 100. I'll check book later Link to comment Share on other sites More sharing options...

You either missed out Talc: 9.0 or Frit 3124: 9.0 , or your maths needs some work. Link to comment Share on other sites More sharing options...
Biglou13 Posted September 29, 2014 Report Share Posted September 29, 2014 Ok. I've already made a amount of this glaze..... As my research on it continues . Others on the net say this glaze is not mature and most likey under fired. Which points in the direction of leaching and unsafe for food use. There are updates/ revisons on this In original form VC 71 is Xavier's jade green with colorants. Revised versions have the formula changed..... I'm told for the safer Link to comment Share on other sites More sharing options...
oldlady Posted September 29, 2014 Report Share Posted September 29, 2014 try this Wettlaufer 18 cone 6 oxidation (electric kiln) C-6 spar (soda spar) 40 i used Kona whiting 15 Ball clay (C&C for whiteness) 20 silica 325 15 dolomite 10 total 100 add 2 % bentonite this is a great glaze, i have tested colors under it and it does not contain zinc so green stays green. used on my little loafers white clay it gives a soft, velvety bright white look. it is described in the book as "waxy" which is something i do not understand. i have used Stroke N Coat colors on top of this glaze and the contrast of the velvety white with the shiny colors adds something special.

You either missed out Talc: 9.0 or Frit 3124: 9.0 , or your maths needs some work. You are 100% correct! I did leave out the Talc. My math skills are poor so I do rely on Excel BUT it looks as if I need to proof my typing as well! Link to comment Share on other sites More sharing options...
