Iron-(III)-chloride hexahydrate granules

to be solved in water. Suitable for etching copper and metals like zinc, bronce, silver, brass and steel

Ferric Chloride due to its properties is the ideal etchant for metal and does not cause health damage if used appropriate.

Suitable for: tray, etching tank, spray etching tank


  • ferric chloride etches straight and precise
  • almost indefinitive shelf life
  • very effective - 1 liter of ferric solution is able to absorb up to 100 gram of solved metal
  • safe if used appropriate
  • no acid but a corrosive salt.
  • Formula: FeCl36H2O
  • CAS Number 10025-77-1


  • for a strong etchant mix in a ratio of 1 to 1 with water ( e.g. 1 kilogram Ferric Chloride + 1 liter water)
  • more subtle works may be etched in a thinned solution of up to 1 to 4 ( e.g. 1 kilogram Ferric Cloride + 4 liter water)
  • the ideal fast etching temperature is around 47 degree centigrade but works already at room temperature
  • stainless steel requires a warmed etching bath
  • the etchant should be in steady movement to prevent the slurry which is produced during etching to sink into the lines

Safety and disposal:

take the usual precautions when working with chemicals: safety glasses, safety gloves, and safety dress

when preparing the solution good aeration or an exhaust hood is required

avoid direct skin and eye contact and do not inhale fumes
