You may wish to keep these small particles for later projects such as painting; however, we are not using them at this time. The gains left in the larger mesh size trays are supposed to provide the most clarity.
Washing Method: (Note: Washed enamels deteriorate faster than unwashed. Just wash the amount you expect to use for your current project.)
Place some transparent enamel in a small cup and add enough distilled water to cover it.
Swirl the water around in the cup and allow the enamel to settle to the bottom. The water on the top will be cloudy.
Plan to capture the fines in the cloudy water since you don't want these going down the sink. Prepare a container with a coffee filter supported at its opening. Gently pour off the cloudy water through the filter. The larger grain enamels will remain in the cup. The fines will catch in the filter while the water goes to the bottom. You will use this container and filter several times.
Repeat steps 1-3 until the water about the transparent enamel is relatively clear.
Wick the excess water from the enamel using the corner of a paper towel. I do this several times.
We are not using the transparent for wet packing; however, if you were, it would now be ready for use. If you are using dry transparents, any moisture from the washing must be removed. Spread the wet enamel on a piece of paper and let it dry completely. This will take considerable time, but damp enamel won't sift. (Note: embossed paper towels do not work well and waste enamel by trapping it.) You may want to place another piece of paper over the drying enamel so it won't be contaminated.
