What is Marble’s reagent?

Marble’s reagent is a solution of copper sulphate (CuSO4) and hydrochloric acid (HCl) dissolved in water. A standard mixture contains 4 g CuSO4 and 20 ml HCl added to 20 ml water. It forms a green solution, with a pungent acidic odour and a pH below 1.

What is it used for?

Marble’s reagent is used as an etchant for various types of metal alloys. Etching is the process of applying a strong acid solution to “burn” areas in a metal surface that are not protected to create a design. There are many different etching solutions, depending on the type of metal used. This is an ancient technique, probably developed around the 15th century.

When using this solution, material to be etched should be immersed or swabbed for 5 to 60 seconds. It’s most appropriate for etching nickel (Ni), nickel and copper (Ni-Cu) or nickel and iron (Ni-Fe) alloys and superalloys. A few drops of acid sulphuric (H2SO4) can be added to increase activity.

Safety measures

As a solution containing a strong acid, it is essential to follow important safety measures. All information available in the Material Safety Data Sheet. Appropriate protective clothing should be worn, including suitable respiratory equipment during spraying operations. Frequent change of gloves is advisable, as the solution may seriously damage the gloves and cause skin burns.
