- 1). Put on the rubber gloves before handling mercury in any way.
- 2). Place the chamois cloth inside the glass funnel (think of it as a sort of coffee filter for the mercury).
- 3). Place the glass funnel inside the bottle, and pour the mercury (no more than 100cc at a time, so the bottle doesn't get too heavy) into the filter so that it falls through the chamois cloth, removing any large impurities.
- 4). Combine 10cc of water with 25 grams of Mercurous nitrate crystals, and pour into the flask with the mercury.
- 5). Close the flask, and swish the mixture gently for about 5 minutes.
- 6). Wash the mercury with water in a bucket. The impurities in the metal will have been absorbed by the nitrate crystals, and you'll be left with very shiny, clean-;ooking pure mercury once you pour off the water.
