Try this: mix equal parts by volume of lead letharge and calcium
carbonate with enough distilled water to SLOWLY bring to a clump. (I
did one tablespoon of each, and the first time I did it, the water
went from not enough to way too much in just a few drops.) Let the
ball dry completely.Once dry, rub it on a window screen to create
dust. Use this dust at 1% and see if you like the results.
I have done this with rutile and it did nothing remarkable.
