Chrome-tin (either from the raw materials or a stain) pink and red glazes can be difficult to achieve and keep consistent at cone 6. In ceramics, red is perhaps the most difficult and most expensive color in ceramics. The chemistry of the host glaze has to be sympathetic to the color development, the chrome and tin require high calcium, zero zinc and low boron (if the chemistry is wrong the color will likely be grey). Glazes that do work in this system are normally highly fritted, and as such are more expensive and difficult to work with. However this Ravenscrag base has beautiful working properties, you can do multiple layers and it has all the other benefits imparted by a high Ravenscrag Slip content. However, keep in mind that red is red, it is difficult; test this first on different kinds of clay to determine if is is suitable for you. Again, remember that tin is expensive, it may be better to use a pink or maroon chrome-tin based stain instead (although they are not much lower in price).

Medium to medium thick application is best. Breaks clear around edges to highlight irregularities in the surface. On darker bodies the red color is darker. Slow cooling can matte the surface.
