Development of methods for production of artificial copper patina
Original language description
This work is focused on development of a method for production of artificial copper patina pigment based on brochantite. A suitable titration method for this type was chosen to add sodium hydroxide solution to cupric sulphate solution. Following parameters were studied: solutions concentrations, ferric ion addition, dosing rate of titration, stirring intensity. Produced pigment was studied by means of XRD (phase composition), spectrophotometry (colour) and SEM (morphology). In the first stage the suitability of this method was verified in small portions when the volume of cupric sulphate solution was less than 100 ml. In these experiments, the suitability of the method was confirmed both for pure copper sulphate and cupric sulphate solution with the addition of ferrous sulphate heptahydrate, which provide colour closer to natural patina. After successful confirmation of the suitability of this method, it was passed to the second stage when this procedure was tested at large doses, the volume of cupric sulphate being 5 liters. The results indicate that this procedure is applicable to a pure copper sulphate solution, but not to a mixture of copper sulphate and iron sulphate.
