What comes off any melter still needs filtering before it is worth selling. The first pass, straight off the heat, is coarse: cheesecloth or a paint-strainer bag catches bee parts, propolis flakes, and other debris large enough to see. A second pass through a much finer mesh, one hundred to two hundred microns, or an old nylon stocking after a re-melt, is what turns a rough block into something a cosmetics or candle buyer will accept.

The market sorts what you produce into a handful of grades:

  • Cappings wax, palest and most valuable.
  • Rendered and filtered wax, yellow and generally useful.
  • Unfiltered rough block, dark and sold at an industrial discount.
  • Pharmaceutical or cosmetic grade, filtered multiple times and sometimes bleached, which commands the highest price of all.

One extra filtering pass is often the cheapest upgrade you can make to a batch.
