Shelly M Posted May 14, 2016 Report Share Posted May 14, 2016 I'm looking for a white slip recipe to use over red earthenware clay for doing sgraffito. I came across this one but want other options. If anyone has other recipes to share, I am most appreciative of your offerings. This is one I found by Martina Lantin in a Ceramics Monthly book: Nepheline Syenite 15% Talc 15% Ferro Frit 3124 10% Ball Clay 40% EPK Kaolin 20% 100% Link to comment Share on other sites More sharing options...
alabama Posted May 14, 2016 Report Share Posted May 14, 2016 Hey, S and J pottery is widely known for their sgrafitto. Their web site is www.sjpottery.com They used to demonstrate at Manskers Station (Nashville, tn) back in the 1990s. They are very talented and nice also!!! I also went to www.amerheritage.com and looked at their examples for you...though I wasn't able to look at the red ware! . Then I went to www.bing.com and searched "sgrafitto white slip recipe" and several responses came up, including one from CADs 2011 archives... That one was good!! I tried the sgrafitto around 2002 or so...it didn't work for me, probably the clear glaze went on too thick and turned the entire piece a muddy grey. My favorite pottery book, Pre-Industrial Utensils, 1150 - 1800, has an example on page 125, of a sgrafitto bowl circa 1594 ad. Good luck Alabama Link to comment Share on other sites More sharing options...
Min Posted May 14, 2016 Report Share Posted May 14, 2016 I haven't used this for scraffito but have used it on low fire terracotta, it's super white and you can put it on thickly without problems. It's the fish sauce slip recipe with macaloid instead of bentonite. (I got iron speckles with white bentonite so I got rid of that and went with the macaloid, which I think is now called bentone or something like that) Minspar 200................. 27.50Grolleg Kaolin.............. 40.80Pyrophyllite................ 8.30Silica...................... 17.00Macaloid.................... 6.30=========99.90 Link to comment Share on other sites More sharing options...
bciskepottery Posted May 14, 2016 Report Share Posted May 14, 2016 If you have some porcelain, slake it into a slip and apply. Or, buy some dry porcelain from you supply dealer. Link to comment Share on other sites More sharing options...

So, a person could put porcelain slip over a red or brown clay body? You wouldn't have to worry about cracking, etc? r. Link to comment Share on other sites More sharing options...

Applied at leatherhard (soft to medium) and the two should dry together without cracking, etc. Dipped or brushed. Keep thickness of application more on the thin side than thick side.

oldlady Posted May 15, 2016 Report Share Posted May 15, 2016 bruce, i thought the same thing and used some slip made with Danish White, a cone 8 clay. made probably 15-20 separate colors. applied it to cone 6 clay. worked fine until it began to peel off the finished pieces in some places. it hurt to get rid of all the colors.

Not familiar with Danish White. I've used Helios Porcelain from Highwater with no problems, including mixing it with Mason Stains. Am trying some Standard 130 that I was gifted from another potter.

Babs Posted May 15, 2016 Report Share Posted May 15, 2016 I use a porcelain for this purpose with a titch of sodium silicate, no problems UNLESS the pots are just a little too dry. Often this is not an apparent prob till bisque when it can "bloat" away from the body. Link to comment Share on other sites More sharing options...

Magnolia Mud Researdh Posted May 16, 2016 Report Share Posted May 16, 2016 I use a slip made from my favorite white earthenware clay body, and since it (white earthenware clay body) comes from the same clay supplier as the white version of the red clay body, the shrinkage issue is minor. On porcelain and stoneware, I use often use slip made from a different clay body for decorative purposes, especially for sgraffito. I even use earthenware slip on cone 10 stoneware as a "glaze - like" treatment. It is a good idea to try it as a test before using it on your MFA final exam piece.
