Acid Resistant Gloves Goggles



Preparation: In a Barrel placed 3 liters of water and pour 1 Iron liter of ferric chloride, closes and moves slowly to mix (no sudden movements). Allow to rest.

Use: in a plastic tray ready pour the acid and the iron is immersed in the amount of time desired. The longer immersed in the acid the greater the depth lines.

Environmental Precautions and Care:
- Use in well ventilated areas
- Wear gloves
- Dilute Calcium Carbonate (Crete) and empty into the sink to minimize the impact of acid in water (Calcium carbonate is an alkali and reacts with iron perchloride, care must be taken when large amounts of acid are also the cause alkali burns to the eyes, so that should take protective eyewear).

Edinburgh Etch acid preparation for stronger bites:
(Friedhard Kiekeben)

1 - Prepare 250 gr. Citric Acid (sold in pastry shops for jams) + 3 / 4 liter of water.

2 - Then it is mixed with ferric chloride Iron (previously prepared as described above: 1lt perchloride + 3LT water)


The advantage of the Edinburgh Etch is that the acid acts more quickly and leaves no sediment, ideal for Technique Terrazas.
