Iron chloride (for etching)

Ferric chloride for etching.
Ferric chloride is sold in a plastic bag packing 50 gr. - 180 rub.
a jar of 250 gr. - 750 RUB.

Fire and explosion proof.
Be sure to use personal protective equipment during operation.
The degree of impact on the body relates to the substances of the 3rd hazard class.

Application:
Chlorine iron is mixed with hot water. On this bag (50 gr.) approximately 150 - 250 g of water.
Pour in very small portions, stirring constantly the solution. When dissolved, the water is heated. Stir to mix and dissolve the powder (about 15-20 minutes).
Then immerse the metal plate in the resulting solution (COMPLETELY!) .
During etching, the temperature of the solution should be maintained in the redistribution of 50 degrees ( this can be done using a water bath - adding hotter water to it. Thus, etching will occur much faster.

The spent solution can be drained into a glass container, closed with a lid and left for an indefinite period for the next etching.
