| (54) | PROCESS FOR COATING ALABASTER PLATES FOR ORNAMENTAL PURPOSES |
| (57) A method for coating alabaster plates with an ornamental purpose consisting of coating
an alabaster plate (3), fixed or not, on a wall or surface (1), with a transparent
varnish (6), reflectant material (5), stained pigmentation (4) and a fluorescent coating
(2'), the transparent varnish (6) being replaced, if desired, by an oil (7), and being
- able to receive light from an artificial light emitter, such as ambient light or
black light, on the front or rear side of the alabaster plate (3), and the alabaster
plate - (3) can be faced with a fosforescent pigment coating (2), too, diluted in
a transparent paint. |
BACKGROUND OF THE INVENTION
[0001] The present specification relates to a method for coating alabaster plates with an ornamental purpose, the evident object of which is to succeed in changing the alabaster shade under the ambient light through the application of a coating, starting from a fluorescent pigment, or else by using an inner light source, so that changing lights and mixing both the pigment colours and the colours of the lights passing through the plate, colours different from those used can be obtained, the - phosphorescent light emission from the alabaster plate being held up in all cases, when the luminous sources cease.
FIELD OF THE INVENTION
[0002] This invention will find application in the industry dedicated to the building field and, in a most definite manner, to decorating and ornamental works in edifices.
RELATED ART
[0003] On the applicant' s part, nothing is known about the existence, at present, of any method contemplating the coating of alabaster plates with an ornamental purpose.
SUMMARY OF THE INVENTION
[0004] The method for coating alabaster plates with an ornamental purpose, as proposed by the invention, constitutes, per se, an evident novelty in its application field, since starting from the utilization of this method, it is possible to enhance the brightness of the alabaster plates covering a facing, and even a wall or partition made of alabaster, the interface of two plates of this material being processed, and the coating being incorporated into the zone through which the plates are joined, such as when used in large windows, - glass windows, screens, and so on; the coating effects on the plates persisting when a luminous source stops being applied, and allowing several effects with natural or artificial light, and even mixing both, to be - created.
[0005] In a more definite way, the method for coating alabaster plates with an ornamental purpose of the invention, is constituted starting from the application or fastening, in a first embodiment, of alabaster plates or slabs having different sizes and shapes, which, in general, are fastened, at one of their faces, on a wall, or facing, so brightness, fluorescence, phosphorescence, reflectance, etc., being obtained, the application being performed on alabaster slabs of different pigments, both solid and liquid, such as metallic oxides, metallic powders, acrylics, enamels, metallized paints, plastic paints, or else on organic and inorganic bases, as well as stained acetates, stained glasses, plastics and paper, also stained.
[0006] Once this operation has been made, different shades and colours are, in turn, obtained, these effects reaching the point of being spectacular, depending on a direct or indirect light, and, at the same time, whether the light is natural or artificial, good effects being also obtained, both indoors and outdoors.
[0007] The alabaster plates can be fastened or fixed on - vertical or horizontal ornamental coyers, and, also, be in a floating state on a fastening point placed at one or several points in hollow spaces on supports.
[0008] In this method, a fluorescent effect is contemplated, which is obtained with the ambient light, changing the shade of the alabaster.
[0009] By using internal light (that is to say, by transparency), according to the light colour, as well as - the fluorescent pigment colour, different fluorescence effects are obtained, when the light passes through a previously painted alabaster plate.
[0010] Likewise, by using external light, after applying a cover of fluorescent pigment, the light has a rebound effect, and then a very different effect is obtained, depending on the pigment colour applicated and that of the light used.
[0011] If a first coat of fluorescent paint, and a second coat of pigment, is applied, independently on whether the latter will be plastic, clinical, oxide, enamel, etc., the effects with an internal light will be different, according to the light change, and mixing both the pigment colours, and the lights colours, which pass through the alabaster plate, different colours from - those used will be obtained, a great possibility being atained on being mixed ones others.
[0012] Also, the method makes possible that the alabaster, under ambient light, will be chromatically enhanced in different colour ranges, since the light mixes the colours ones others, the result being the obtaining of new colours and shades, according to the applications previously performed.
[0013] Also, under the external light, it is obtained that the rebound effect of the first fluorescent coat results in that the alabaster slabs may give different effects, depending on the light type applied to, and where the - application is performed from, great brightness shades being obtained.
[0014] Likewise, the method contemplates to apply a first coat of pigment, and a second coat of fluorescent paint, so that, under interior light, very fine effects can be attained when the light is passing through, and several coats are being applied to, and, at the same time, the main change existing between the fluorescent affect and the application of a first coat of fluorescent paint and a second coat of pigment, is increased under an external light.
[0015] Under the ambient light, markedly more blended effects and a great variety of shades are obtained.
[0016] It should be pointed out that the obtained fluorescent effect, both under interior and exterior light, once the production thereof is ceased, that is to say, the light is off, the alabaster plate is still emitting phosphorescent light, this embodiment being capable of being applied together with the preceding ones, keeping zones which will produce a phosphorescent effect, giving shades of these characteristics in a more or less diffused way, or more or less extended on the alabaster plate, being even capable of representing areas and lines reproducing drawings, adornment, etc., or, on the contray, being capable of enhancing the expected areas and multiplying chromatic possibilities of the previous ones.
[0017] While the light is on, the phosphorescent pigment will intervene in the assembly with the colour it brings, interacting with the other applicated colours or areas, but when the light is off, it will emit a brightness - which is appropiate to the phosphorescent effect, which, as known, is green.
[0018] The application of the phosphorescent paint is made easy if it is previously blended with a phosphorescent paint.
[0019] The phosphorescent pigment can be blended with the above mentioned pigments; for example, when the phosphorescent application is to cover the whole alabaster plate.
[0020] In principle, all the former applications were arranged so that the alabaster plate could be processed at only one side, which, in general, was leant against a wall, floor, ceiling, etc, being only exposed to the observer view the non processed face of the alabaster plate, but, nevertheless, the processing can be performed, likewise, between two alabaster plates, the processing remaining in the middle of the two alabaster plates, forming a kind of sandwich, allowing it to be applied, as already said, to glass windows, screens, etc.
[0021] Lastly, it should be pointed out that the pigments - are applied in a conventional way, being previously dissolved in a solvent, being previously blended before to be applied, and obtaining previous colour blends.
