Description

KAISERLICHESIMPERIAL

PATENTAPATENTA

Von den zahlreichen Verfahren, welche dazu dienen sollen, Gypsabgüsse in eine luftbestä'ndige, abwaschbare und härtere Masse zu verwandeln, ist es nur eins, das in gröfserem Mafsstabe Verwendung findet. Es ist das die sogen. Elfenbeinmasse, welche erhalten wird, wenn man die geformten Gegenstände entweder in geschmolzenes Stearin oder Paraffin eintaucht oder mit alkoholischen Lösungen der genannten Stoffe tränkt. Obwohl diese Masse vom künstlerischen Standpunkt manches zu wünschen übrig läfst, hat sie sich doch in Ermangelung einer besseren allgemein eingebürgert. Es ist nicht zu leugnen, dafs die so präparirten Gegenstände sich leicht von Staub u. dergl. reinigen lassen, dafs sie wesentlich härter sind als der reine Gyps; dagegen zeigen sie ein stumpfes Aussehen und einen unangenehmen Glanz, der den künstlerischen Eindruck wesentlich stört. Aufserdem dringt die Stearinsäure nur wenig tief in die Masse ein.Of the numerous processes that are intended to be used to convert gypsum casts into an air-resistant, To transform washable and harder mass, it is only one thing that is used on a larger scale. It is that sucked Ivory mass, which is obtained by looking at the molded objects either immersed in molten stearin or paraffin or with alcoholic solutions of the mentioned substances soak. Although from an artistic point of view this mass is too much leaves something to be desired, but it has failed a better generally naturalized. It cannot be denied that it is so Prepared objects can easily be cleaned of dust and the like, so that they are essential are harder than pure Gyps; on the other hand, they have a dull appearance and an unpleasant one Shine that significantly disrupts the artistic impression. In addition, the stearic acid penetrates only a little deeply into the mass.

Nach dem folgenden einfachen Verfahren erhält man dagegen eine Masse von mindestens gleicher Härte und Widerstandsfähigkeit, als die oben beschriebene, die ebenfalls durch blofses Abwaschen sich leicht reinigen läfst, aufserdem aber den Gyps bis zu einer gewissen Tiefe durchscheinend macht, den Abgüssen dadurch ein steinähnliches Aussehen giebt und ihnen einen so warmen, künstlerisch schönen Ton" verleiht, dafs man es mit einem ganz anderen, edleren Material zu thun zu haben vermeint.On the other hand, the following simple procedure gives a mass of at least same hardness and resistance as the one described above, which is also due to Mere washing up is easy to clean, but also the Gyps up to a certain point Makes the depth translucent, giving the casts a stone-like appearance and gives them such a warm, artistically beautiful tone that one can do it with one believed to have done quite different, nobler material.

Durch vorsichtiges Abreiben mit weichem Leder, oder einem seidenen Tuch kann man den Gegenständen eine schöne Politur verleihen. By carefully rubbing with soft leather or a silk cloth, you can give the objects a nice polish.

Das Verfahren ist folgendes:The procedure is as follows:

Die Gypsgüsse werden in einem Gefäfs vollständig mit Leinöl Übergossen und nunmehr allmälig auf eine Temperatur von 70 bis 900 erwärmt und so mindestens ι ο bis 12 Stunden belassen. Nach dieser Zeit hat sich der Gufs vollständig mit dem OeI getränkt; man nimmt ihn jetzt heraus, reinigt ihn von dem aufsen anhaftenden OeI und überläfst ihn an einem vor Staub geschützten Ort einfach der Einwirkung der atmosphärischen Luft. Durch den Sauerstoff der letzteren verwandelt sich das zu den sogen, trocknenden Oelen gehörige Leinöl in eine durchscheinende feste Masse, welche die oben beschriebene Wirkung ausübt. Dieses Eintrocknen verläuft verhältnifsmäfsig schnell; der charakteristische Geruch des Leinöls verschwindet bald, und ebenso fetten die Gegenstände nach kurzer Zeit nicht mehr ab.The plaster casts are completely poured over with linseed oil in a vessel and then gradually heated to a temperature of 70 to 90 0 and left in this way for at least 12 hours. After this time, the Gufs has soaked itself completely with the OeI; one takes it out now, cleans it of the externally adhering oil and leaves it simply to the action of the atmospheric air in a place protected from dust. The linseed oil, belonging to the so-called drying oils, is transformed into a translucent solid mass by the oxygen in the latter, which has the effect described above. This drying-out proceeds comparatively quickly; the characteristic smell of linseed oil soon disappears, and the objects no longer grease after a short time.

An Stelle von Leinöl können selbstverständlich auch andere trocknende OeIe, wie Mohnöl, Hanföl, Ricinusöl u. dergl., benutzt werden, doch empfiehlt sich das erste schon wegen seiner Billigkeit.Instead of linseed oil, other drying oils, such as poppy seed oil, can of course also be used. Hemp oil, castor oil and the like can be used, but the first is recommended because of its Equity.

Obgleich man das Leinöl bekanntlich durch Kochen mit Metalloxyden leichter trocknend machen und dadurch den Procefs beschleunigen kann, so ist das unpräparirte OeI in jeder Beziehung vorzuziehen, weil es eine gleichmäfsigere und schöner gefärbte Masse ergiebt.Although it is known that linseed oil can be dried more easily by cooking with metal oxides can make and thereby accelerate the process, so is the unprepared oil in every respect preferable because it gives a more even and nicely colored mass.
