Sorry for the Pink Floyd reference in the title.
So new here and also new at cleaning. I've resurrected my interest in collecting Paulson solids that started back in the 80's. So.... I recently got a batch of "yellow" chips from an unnamed source. They definitely needed a bath, so here we go. (I did already have an ultrasonic cleaner on order, but needed something to do)
Got Oxiclean and mixed about 1/2 tbsp in a saucer of hot water. Now that tells you already I'm not an "exact" kind of guy. Soaked about 3 minutes and started scrubbing with something the wife had that kind of resembled a tooth brush.... RIght away with one of the chips I noticed brownish splatters coming off the chip in the sink. I looked and sure enough the clay color was transferring after rubbing with a paper towel. I should now say I'd noticed I had at least 2 different shades of yellow in this batch. I'm guessing using the Paulson color chart, what I actually have is "mustard" and "daisy". The "mustard" chip was the one I was holding when I noticed the color transfer. Never had the issue with the daisies, but all 3 mustards exhibited this problem, so I stopped cleaning using this method. I'll wait for the ultra sonic cleaner to finish those.
So... why did this only happen with the mustards? Same water mix, same water temp, same everything..... I probably did 20 daisies with NO color transfer at all.
