Flashing Slips
Flashing slips can be defined as a refined liquid clay that is typically applied to the surface of wares in either the green stages or bisque stage. The “flashing” part of the slip is found within the impurities in the kaolin such as iron and magnesium which interact with the atmosphere and cause blushing from the soda, salt or wood.
RF Studio East Soda Slip (Adapted) ^6, ^10
The RF Studio East Soda Slip is a slip from the University of Wisconsin-River Falls archives and one that I have been used since the beginning of my soda firing journey in undergrad in 2016. I am always amazed with the range in color that I pull from this slip in both wood and soda firings. I have used this in soda at ^6 and ^10 with superb results. It has been adapted to use Glaze Rite as the suspender for my personal studio use. The slip is formulated for bisque ware, but I dip my pots bone dry into a thinned slip.
