Lawrence : Citric Acid : 200g

Lawrence Citric Acid is used to create an effective etchant for copper and brass. Citric acid will improve the etching potential of ferric as well as dissolving the sediment, enhancing its performance and producing a precise etch. The advantage of using it over straight ferric is that it can be used in flat trays with the plate face up, as well as in vertical tanks.

Ensure appropriate protective clothing is worn to avoid inhalation and contact with skin and eyes.
