3 How Acid bite shadow

Formula 3.

This liquid mixture is very dangerous. Must follow strict procedures for mixing. And while using a dangerous gas species Nitrogen oxide. Nitrogen oxide. Sulfur oxide, etc., requiring a vacuum, these toxic fumes. And ice mask.

Mixing

1. the water, 350 cc. into a plastic container.

2. only gums Ma Sulfur acid concentration (specific gravity 1.84) 500 cc. into the water, slowly pour the liquid slowly, stirring to combine.

3. Leaving the solution cool to room temperature before Leave at least 3 hours (do not do the next step where the hot liquid.)

4. When the solution cooled down, take nitrate concentration (specific gravity 1.38) 185 cc. to go slowly.

5. Add salt to 1.5 grams.

Limited use of copper, nickel silver, brass or copper will give a good surface shine bright

Cautions Do not Sulfur acid + nitrate Before the final. May cause a serious reaction to the explosive stage.
