Reason for treatment
consolidative electrolytic reduction
The object presents a wax coating and white corrosion products from the lead specially located on the deeper parts of the decoration and around the hole. These are evidence of active corrosion and so of the instability of the seal which perturbs and hides also the surface. No remains of organic material are visible.
White corrosion products were treated with a local electrolytic reduction using cotton swabs on a stainless steel tweezer and a solution of sulphuric acid at 10% in deionised water at a very low current density of less than 1 mA / cm2. Some white products didn’t respond to the treatment and were left.
