Sy. 23Flint 12Total 100%Development:The purpose of my research was to come up with two different slips to be applied during theleather hard stage to the 570 body, commercial mason stains were then added for color. Oneof the two base slips was a whit slip, while the other used the New Zealand Kaolin.Mason Stains were added in 10% additions...Mason Dark Red- 10%Mason Nickel Silicate - 10%Mason Best Black- 10%Mason ZR VN Blue - 10%Mason Pink- 10 %Mason Violet- 10%After the initial testing of my base slips both slips broke on the edges of the test tiles. However these testwere only demonstration one dip. After adding the colorants to the slips, the test tiles were dipped twice.The second test showed that the fit was inadequate, as the slip flaked off most of the tiles. In the future Iwould modify the base slips to get a better fit as well as increase the percentage of mason stains.62
