The yellow staining is most likely just from the water in the slip. It should burn out. Is this truly a slip, though? Slips will not adhere to bisque....
Thanks. Some of the yellow has faded so I think you are right. The slip is mostly alberta slip clay and OM4 with chrome oxide, cobalt carbonate and red iron oxide added. Recommendations from instructor say can be used on bone dry or bisque ware but best on bisque. It's a really intense black. I've used it before on greeware and over glazes to make marks. Hope this works as well!

I've successfully used a 50/50 mix of kaolin and ball clay on stoneware bisque - can add oxides if required.
