Restoration of a Lidded Beaker Made Using the Electrotyping Procedure Zsuzsanna Markaly Copied from another beaker using the electrotyping (galvanoplasty) method, this lidded beaker may have been made around the turn of the 20th century, in the studio of Károly Herpka the Younger. Called the Institute for Electrotyping, this operated within the framework of the Museum of Applied Arts, Budapest. It was in this studio that electrotyped artefacts were first made in Hungary. The original beaker, silver-gilt Hungarian goldsmith’s work made in 1596, is currently on display in the historical exhibition at the Hungarian National Museum. The base material of the artefact featuring in the study is copper, which was first silvered and then given a coating of gold. According to the findings of investigations using X-ray fluorescent spectroscopy, the material of the beaker’s foot, its upper edge, and the dragon figures decorating its sides is brass. Consequently, these parts were made not using the electrotyping method, but by casting. The surface of the object was covered by a layer of silver sulphide corrosion. In places, the gilding had come off to reveal the copper beneath. On the inside of the beaker, and of its lid, the gilding had survived comparatively intact. Of the dragons decorating the sides of the cup part, one was missing. Originally, the cup part was affixed to the foot by three small nails, of which all were missing. It had been re-attached provisionally using wire. The lid was deformed, dented in a number of places, and cracked in two places; moreover, the edge of it was completely bent inwards in one place. Washing with a surface-active liquid was followed by treatment with a silver polish suitable for the removal of the black silver sulphide. This was followed by neutralisation using sodium bicarbonate. After this chemical cleaning, the artefact was greyish in colour: the gilding could be made out only in places. The deformed 136
