Be sure to take proper precautions when using product (wearing Protective Gloves, Glasses & Apron, etc.)
Inhalation: Remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical attention immediately.
Ingestion: Do Not Induce Vomiting. Give large quantities of water, then an antidote such as sodium bicarbonate or anti-acid tablets to neutralise the acidity of the Ferric Chloride. Never give anything by mouth to an unconscious individual. Get medical attention immediately.
Skin Contact: Flush skin with water. Removed contaminated clothing; wash before reuse. If there is skin irritation, get medical attention.
Eye Contact: Immediately, flush with large amounts of water for at least 15 minutes while holding eyelids apart. Washing within one minute is essential to achieve maximum effectiveness. Get medical attention after flushing.
General etching procedure
- De-grease blade with acetone.
Mix ferric chloride with distilled water (one part water, two parts acid) -OR- mix 60% ferric chloride and 40% white vinegar.
Submerge the blade in the acid mixture, and let sit for a few minutes.
Remove to see the etched pattern.
Rinse the blade with warm water and (if you want a deeper etch), rub blade lightly with 000 steel wool before putting it back in the acid until the desired etched depth is achieved.
Etching time required depends on how deep you want the etch to be and what kind of contrast you want.
On the last dip, remove blade from acid and allow the black oxidation to stay on the blade rinse in warm water & liberally cover the blade in baking soda to neutralise the acid.
Dry the blade off, and wipe down with WD-40 or Fluid Film. You can also sand off the oxidation with 600 grit wet/dry sandpaper, if desired.
