Description

Descrizione del brevetto per invenzione industriale avente per titolo: Description of the patent for industrial invention entitled:

" Procedimento di lavorazione del vetro, in particolare per ottenere vetro stratificato policromo o monocromatico, specialmente per realizzare gioielli con tale vetro, con eventuale inclusione di materiale decorativo diverso, e gioielli ottenibili a partire da tali vetri " "Glass working process, in particular to obtain polychrome or monochromatic laminated glass, especially to make jewels with this glass, with the possible inclusion of different decorative material, and jewels obtainable from such glass"

Il presente trovato concerne un nuovo ed originale procedimento di lavorazione del vetro, in particolare per realizzare gioielli in vetro policromo o monocromatico, preferibilmente con inclusione di materiali diversi compatibili, in particolare di metalli non preziosi o preziosi, di vario spessore, quali ad esempio lamine o frammenti di oro, argento, platino, rame, variamente sagomate, nonché vetri ottenuti con tale particolare procedimento e gioielli ottenibili utilizzando tali vetri con o senza inclusione di altri materiali decorativi compatibili col vetro. The present invention relates to a new and original glass working process, in particular for making jewels in polychrome or monochromatic glass, preferably with the inclusion of different compatible materials, in particular of non-precious or precious metals, of various thickness, such as foils or fragments of gold, silver, platinum, copper, variously shaped, as well as glasses obtained with this particular process and jewels obtainable using such glasses with or without the inclusion of other decorative materials compatible with the glass.

Nell’arte vetraria sono già noti procedimenti per la fabbricazione di articoli in vetro di vario genere i quali presentano parti adiacenti di colori diversi in modo da formare ad esempio figure od oggetti tridimensionali formati da settori di vari colori, ottenuti utilizzando la fusione successiva di vetri variamente colorati, cui viene data una particolare sagoma, ad esempio di animali, fiori e cosi via. In the glass art, processes are already known for the manufacture of various kinds of glass articles which have adjacent parts of different colors so as to form, for example, three-dimensional figures or objects formed by sectors of various colors, obtained using the subsequent fusion of glass. variously colored, which is given a particular shape, for example of animals, flowers and so on.

Sono pure noti procedimenti per ottenere articoli in vetro utilizzando un vetro di base, colorato od incolore, sul quale vengono appoggiati spezzoni di vetri di colore diverso, i quali vetri si saldano l'uno contro l'altro a seguito del loro riscaldamento in un forno, ottenendosi così un vetro composito a due strati, a sovrapposizione parziale, con superficie in rilievo in corrispondenza della sovrapposizione. ognuno dei due strati di vetro avendo e mantenendo una propria colorazione di partenza. Processes are also known for obtaining glass articles using a base glass, colored or colorless, on which pieces of glass of different colors are placed, which glasses are welded against each other following their heating in an oven. , thus obtaining a two-layer composite glass, with partial overlap, with a raised surface in correspondence with the overlap. each of the two layers of glass having and maintaining its own starting color.

Scopo del presente trovato é di prevedere invece un procedimento nuovo ed originale di lavorazione del vetro tale da consentire la realizzazione di vetri compositi stratificati non presentanti rilievi superficiali formati mediante sovrapposizione di singoli vetri a loro volta stratificati in modo nuovo ed originale aventi colori diversi per cui tali singoli vetri stratificati di colore diverso, una S'olta sovrapposti gli uni agli altri e fusi assieme, risultano separati gli uni dagli altri, in sezione, da strati di vetro incolore e trasparente per cui, dal punto di vista estetico, i colori dei vari strati possono tra loro combinarsi, ottenendosi una variazione del colore e della tonalità cromatica per trasparenza, secondo la tecnica nota della miscelazione dei colori in pittura, i vari strati rimanendo tuttavia distinti su piani diversi di stratificazione. Ad esempio, uno strato di vetro di colore rosso, avente una certa sagoma e dimensione, cui si sovrappone parzialmente uno strato di vetro giallo di sagoma e dimensioni diverse darà, come risultato un'area di colore arancione con bordi o zone di colore rosso e giallo nelle zone in cui non si ha sovrapposizione. Inoltre, sopra questa struttura stratificata di vetro si può appoggiare una lamina o frammento di altro materiale compatibile col vetro, ad esempio oro, argento, platino, rame o altri materiali esteticamente validi, opportunamente sagomato, il quale a sua volta verrà coperto da uno strato di vetro cristallino, ovvero incolore e trasparente, per cui. disponendo il tutto in un forno, si otterrà alla fine un blocco di vetro stratificato policromo o monocromatico con inclusione, ad esempio, di una lamina d’oro perfettamente visibile, che verrà poi calibrato nonché lucidato, per esaltare così la composizione cromatica e per ottenere sfumature di colore, consentendo di realizzare un gioiello, dopo essere stato calibrato ed incastonato, di aspetto nuovo, originale e gradevole. The purpose of the present invention is instead to provide a new and original glass processing procedure such as to allow the production of laminated composite glasses without surface reliefs formed by overlapping single glasses in turn stratified in a new and original way having different colors so that these individual stratified glasses of different colors, one S'olta superimposed on each other and fused together, are separated from each other, in section, by layers of colorless and transparent glass so that, from the aesthetic point of view, the colors of the various layers can be combined with each other, obtaining a variation of color and chromatic tonality by transparency, according to the known technique of mixing colors in painting, the various layers remaining however distinct on different layers of stratification. For example, a layer of red glass, having a certain shape and size, which is partially superimposed on a layer of yellow glass of different shape and size, will result in an orange color area with red and red borders or areas. yellow in areas where there is no overlap. Furthermore, a sheet or fragment of other material compatible with the glass, for example gold, silver, platinum, copper or other aesthetically valid materials, suitably shaped, can be placed on top of this stratified glass structure, which in turn will be covered by a layer crystalline glass, i.e. colorless and transparent, so. by placing everything in an oven, at the end, a block of laminated polychrome or monochromatic glass will be obtained with the inclusion, for example, of a perfectly visible gold sheet, which will then be calibrated and polished, to enhance the chromatic composition and to obtain shades of color, allowing you to create a jewel, after being calibrated and set, with a new, original and pleasant appearance.

Ciò è reso possibile utilizzando una tecnica del tutto particolare ed originale che verrà qui descritta dettagliatamente. This is made possible by using a very particular and original technique which will be described in detail here.

Il procedimento della presente invenzione prevede le seguenti fasi: The process of the present invention provides for the following steps:

1- soffiatura in stampi cilindrici di vetro incolore ovvero cristallino in modo da realizzare elementi cilindrici cavi ad estremità chiuse; 1- blowing into cylindrical molds of colorless or crystalline glass in order to obtain hollow cylindrical elements with closed ends;

2- soffiatura di vetri colorati costituiti da uno strato di vetro incolore trasparente avente uno spessore da circa 1 ad 8 mm , da uno strato di colore intermedio e da uno strato sottilissimo di vetro incolore per ottenere elementi cilindrici cavi colorati ad estremità chiuse, ognuno di colore diverso a seconda dei colori che si vogliono utilizzare per lo scopo finale. Il colore di ogni vetro colorato è compatibile con ogni altro colore degli altri vetri colorati, vale a dire ognuno di tali vetri ha lo stesso coefficiente di dilatazione termica; 2- blowing of colored glass consisting of a layer of transparent colorless glass having a thickness of about 1 to 8 mm, an intermediate color layer and a very thin layer of colorless glass to obtain hollow colored cylindrical elements with closed ends, each of different color depending on the colors you want to use for the final purpose. The color of each colored glass is compatible with any other color of the other colored glass, ie each of these glasses has the same thermal expansion coefficient;

3- asportazione delle estremità degli elementi cilindrici cavi ottenuti con le fasi 1 e 2 per ricavare elementi tubolari di vetro incolore e di vetri stratificati, ognuno di colore diverso; i colori dei vetri colorati possono essere quelli fondamentali o colori compositi; 3- removal of the ends of the hollow cylindrical elements obtained with steps 1 and 2 to obtain tubular elements of colorless glass and laminated glass, each of a different color; the colors of the colored glass can be the basic ones or composite colors;

4- taglio di ognuno degli elementi tubolari di vetro di cui alla fase 3 in senso assiale in modo da ottenere due mezzi tubi di vetro con sezione a semicerchio ; 4- cutting each of the glass tubular elements referred to in step 3 in an axial direction so as to obtain two glass half-tubes with a semicircle section;

5- deposizione di ogni semitubo su di un piano di materiale resistente al calore di fusione del vetro, ad esempio metallico, rivestito di un agente di distacco non inquinante il vetro; 5- deposition of each half-tube on a surface of material resistant to the melting heat of the glass, for example metal, coated with a release agent that does not pollute the glass;

6- introduzione di detto piano metallico supportante i detti semitubi in un forno a muffola per il riscaldamento del vetro ad una temperatura tale di rammollimento del vetro per cui, per effetto del proprio peso, il vetro incurvato a semicerchio tende a distendersi sul detto piano, assumendo pertanto la conformazione di una lastra piana dì vetro: 6- introduction of said metal surface supporting said half-tubes in a muffle furnace for heating the glass to such a softening temperature that, due to its own weight, the glass curved in a semicircle tends to stretch on said surface, assuming therefore the conformation of a flat glass plate:

7- taglio di tali lastre piane di vetro incolore e di vetro colorato per realizzare lastrine di vetro da utilizzare in combinazione le une con le altre: 7- cutting such flat sheets of colorless glass and colored glass to make glass plates to be used in combination with each other:

8- sovrapposizione, su una lastrina di vetro incolore o su una lastrina di vetro colorato ottenute dalla precedente fase, di una o più lastrine di vetro colorato, affiancate o sovrapposte, di forme e dimensioni opportune a seconda delle esigenze estetiche e cromatiche che si vogliono ottenere; 8- overlapping, on a plate of colorless glass or on a plate of colored glass obtained from the previous phase, of one or more plates of colored glass, side by side or superimposed, of suitable shapes and sizes depending on the aesthetic and chromatic needs that are desired obtain;

9- introduzione dell’elemento stratificato ottenuto con la fase 8 in un forno che viene poi portato ad una temperatura opportuna affinché i vari strati di vetro fondano parzialmente e si uniscano l’uno all'altro senza mischiarsi; 9- introduction of the stratified element obtained with phase 8 in an oven which is then brought to a suitable temperature so that the various layers of glass partially melt and join one another without mixing;

10- raffreddamento degli elementi compositi così ottenuti, calibratura alle misure e forme desiderate e lucidatura. 10- cooling of the composite elements thus obtained, calibration to the desired sizes and shapes and polishing.

Secondo una variante dell’invenzione, nella fase 8 la stratificazione prosegue con l'adagiamento . sullo strato superiore di vetro stratificato, di un materiale diverso dal vetro e compatibile con lo stesso, ad esempio una sottile lamina d’oro che è perfettamente compatibile col vetro, dello spessore ad esempio di circa 0,2-0,3 mm , opportunamente sagomata, tale materiale diverso venendo a sua volta ricoperto da uno strato di vetro cristallino, cioè perfettamente incolore e trasparente, dopo di che si prosegue con le succitate fasi 9 e 10. Chiaramente, alla sottile lamina d'oro o ad altro materiale di qualsiasi spessore opportuno, si sarà data una conformazione desiderata, ad esempio una forma a stella, a cuore, a segno zodiacale, e simili. According to a variant of the invention, in phase 8 the layering continues with the laying. on the upper layer of laminated glass, of a material other than glass and compatible with it, for example a thin gold sheet that is perfectly compatible with the glass, for example with a thickness of about 0.2-0.3 mm, suitably shaped, this different material being in turn covered by a layer of crystalline glass, that is, perfectly colorless and transparent, after which it continues with the aforementioned steps 9 and 10. Clearly, the thin gold sheet or other material of any appropriate thickness, a desired conformation will be given, for example a star shape, a heart shape, a zodiac sign, and the like.

Secondo questo procedimento si ottengono elementi lastriformi in vetro policromo o monocromatico con trasparenza dei vari strati presentanti colori che variano da una zona ad un’altra, ed inclusione di un ulteriore elemento decorativo in materiale diverso, il tutto costituendo un elemento perfettamente liscio, senza rilievi, che verrà eventualmente e preferibilmente rifinito mediante incastonatura in una cornice di incastonatura, ad esempio d’oro o di qualsiasi materiale desiderato. According to this process, sheet-like elements in polychrome or monochromatic glass are obtained with transparency of the various layers presenting colors that vary from one area to another, and the inclusion of a further decorative element in different material, all forming a perfectly smooth element, without reliefs. , which will optionally and preferably be finished by setting in a setting frame, for example of gold or of any desired material.

Va posto in rilievo che la lucidatura, oltre che ravvivare la lucentezza della superficie ed incrementare la brillantezza dei colori, serve pure a modificare la tonalità del colore dello strato lucidato, in particolare di quello inferiore, creando effetti di sfumatura dei colori, da una tonalità intensa ad una tonalità più leggera o sfumata It should be emphasized that polishing, as well as reviving the gloss of the surface and increasing the brilliance of the colors, also serves to modify the color tone of the polished layer, in particular of the lower one, creating effects of shading of the colors, from a shade intense to a lighter or more nuanced shade
