Gegenstand der vorliegenden Erfindung bildet ein Verfahren, um in Achat auf chemischem und galvanischem Wege festhaftende Metall-Einlagen anzubringen, was beim Achat bisher nicht erreicht werden konnte.The subject of the present invention forms a method to in agate on chemical and galvanically to attach firmly adhering metal inlays, which was previously the case with agate could not be reached.
Das Verfahren wird wie folgt ausgeführt:The procedure is carried out as follows:
Die Oberfläche des Achates wird zunächst mit einer gegen Säurewirkung unempfindlichen Schicht von Wachs und Asphalt bedeckt. Die gewünschte Zeichnung wird aufgepaust und dann mit der Nadel einradirt.The surface of the agate is first coated with an acid insensitive Layer of wax and asphalt covered. The desired drawing is traced and then rubbed in with the needle.
Ist an allen Stellen, welche mit der Einlage bedeckt werden sollen, die Oberfläche blofsgelegt, dann" werden diese Stellen bis zu der gewünschten Tiefe mittels Flufssäure weggeätzt.If the surface is exposed in all places that are to be covered with the insert, then "these areas are etched away to the desired depth using hydrofluoric acid.
Soll eine bedeutende Tiefe angestrebt werden, so wird der Stein nach der ersten Aetzung von der Schutzschicht durch Abkratzen befreit; dann wird die Oberfläche mit einer neuen Schutzschicht versehen, welche über die Contouren der ersten Aetzung zu deren Schonung etwas hinausgeht, und dann zum zweiten Mal geätzt. Dies Verfahren wird so oft als nöthig wiederholt.If a significant depth is to be aimed for, the stone becomes after the first etching of the protective layer is freed by scraping; then the surface with a new one Protective layer provided over the contours of the first etching to protect them something goes out, and then etched for the second time. This procedure becomes necessary as often as necessary repeated.
Sind diese Manipulationen erledigt, so wird der Stein gereinigt und dessen die Aetzung tragende Oberfläche elektrisch leitend gemacht durch einen auf chemischem Wege erzeugten Ueberzug von metallischem Silber, welcher sich den Rauhheiten der Aetzung innig anschmiegt und durch dieses Hineinwachsen in die Höhlungen und Poren des Steines einen sicheren, fast unlöslichen Träger für einen nachfolgenden galvanischen Niederschlag von beliebigem Metall giebt.When these manipulations are done, the stone is cleaned and its etching bearing surface made electrically conductive by a chemically generated Coating of metallic silver, which closely hugs the roughness of the etching and through this growing into the hollows and pores of the stone a secure, almost insoluble support for one there is subsequent galvanic deposition of any metal.
Sobald der galvanische Niederschlag die eingeätzten Vertiefungen überstiegen hat, wird derselbe zurückgeschliffen und mechanisch beliebig weiter bearbeitet.As soon as the galvanic deposit has exceeded the etched depressions, will the same ground back and mechanically further processed as required.
Es zeigt sich nach diesem Zurückschleifen die Einlage in klaren, scharfen Linien auf der Achatoberfläche und die Einlage kann dann durch Gravirung oder Ciselirung noch weiter bearbeitet werden.After this sanding back, the insert shows itself in clear, sharp lines on the The agate surface and the inlay can then be further enhanced by engraving or chasing to be edited.
