This is the Raku body that my supplier carries. I purchase all my clay from them because their prices are good and more importantly, their products are amazing. Pretty sure this is a clay they make on site. All the clay I purchase from them is made on site.
Wouldn't a thin coating of a refractory slip (low clay content) that fires bright white do the trick over any off white body that has a bit of tooth to it?
Yes the slip sure does well. I use a low fire white earthenware slip and burnish it. I am trying, however, to eliminate this step of the process in just having a white body that works for all the processes I currently do. One clay that does it all!
