This was really, really dirty wax to start with and from the same batch as the other wax. I could not fit it all into the wax melter at once so did separate batches. I had to strain all this wax twice to have it come out clean. I mean I strained both batches of wax twice. The only thing that was different, was when I went on vacation, I left this batch in the solar wax melter all week. It strained slowly because we did not have really hot weather when I left for this vacation. When I got the yellow colored wax, it filtered down through the paper towels in one afternoon. This wax melted slowly as it started to melt a few days before I left. Perhaps in melting so slowly, this happened??
Anyway, I will keep it separate and see what else I get.
