As shown in FIG. 1, a vitreous decorative article 1 according to the present invention comprises, for example, a cubic quartz glass 2 having a polished surface, and bubbles 3 existing inside the quartz glass 2.
The image is drawn inside the quartz glass 2 and is composed of an image 4 of a dragon 4D and a cloud 4C in which the bubble 3 is regarded as a part and the bubble 3 is viewed as a chalcedony.

Since the vitreous decorative article 1 according to the present invention has such a configuration, a method of manufacturing the vitreous decorative article 1 will be described with reference to FIG.

From the ingot of the quartz glass 2 manufactured by the same manufacturing method as in the prior art, an ingot having bubbles 3 is found, and the bubbles 3 are positioned at the position of the chalcedony where the dragon 4D drawn on the quartz glass 2 is held. The ingot is set, and the ingot is cut and polished, for example, so as to be a cubic quartz glass 2 having a side of 15 cm.

A cubic quartz glass 2 having bubbles 3 therein as shown in FIG. 2 is prepared.

Further, two sets of laser devices (both not shown) having the following relationship are prepared.

The first pair of laser devices has a first optical axis 5A of the first oscillation laser beam 5L and a first condensing lens 5A.
Laser means 5 having a first optical axis 5A and 15 °
And has an optical axis 6A of the second oscillation laser beam 6L.
And a laser means 6 having a condenser lens 6R.

The second pair of laser devices includes a laser unit 7 having a third optical axis 7A of the third oscillation laser beam 7L and a third condensing lens 7R, and a third optical axis 7A. Fifteen
The laser means 8 has an optical axis 8A of the fourth oscillation laser light 8L at an angle of ° and has a fourth condenser lens 8R.

Next, the cubic quartz glass 2 in which the bubbles 3 are present is set in a first pair of laser devices and a second pair of laser devices simultaneously.

Thereafter, each optical axis 5A, 6A, 7A, 8
A is such that each of the laser means 5, 6, and 5 has an incident angle of 30 ° with respect to the plane of the quartz glass 2 (the front in FIG. 1).
Adjust 7 and 8.

Further, the oscillating laser beams 5L, 6L from the laser means 5, 6 of the first pair of laser devices are condensed by the condensing lenses 5R, 6R, respectively, so as to be close to the bubble 3 and to the upper portion. Adjust to focus.

On the other hand, the oscillated laser beams 7L and 8L from the laser means 7 and 8 of the second pair of laser devices are brought close to the bubble 3 and focused on the lower portion by using the respective condenser lenses 7R and 8R. Adjust as follows.

As described above, the first pair of laser devices and the second
After adjusting the pair of laser devices, the first pair of laser devices and the second pair of laser devices are connected using a computer in which the shape of the image 4 of the dragon 4D and the cloud 4C is programmed in advance as is conventionally known. While controlling, the dragon 4D and the cloud 4C are drawn.

At this time, as described above, the oscillated laser beam 5L from each of the laser means 5, 6 of the first pair of laser devices,
6L is focused on the upper position close to the bubble 3, so that the first oscillation laser light 5
Energy is concentrated by the superposition of L and the second oscillation laser light 6L, and the energy density is increased, and physical and chemical alterations occur locally in the quartz glass 2 in a very short time.

The vicinity of the focal point inside the quartz glass 2 is melted, and a continuous line is drawn in accordance with the movement of the first pair of laser devices, and an upper image 4Du above the bubble 3 (chalcedony) is drawn. Similarly, the lower image 4 below the bubble 3 (chalcedony) by the action of the laser means 5 and 6 of the pair of laser devices of the first oscillation laser light 5L and the second oscillation laser light 6L.
Dd is drawn. Note that, as described later, the image is divided into the upper image 4Du and the lower image 4Dd of the image 4 so that the bubble functions as an object having a different refractive index in the optical medium through which the oscillating laser beam passes. This is because straight traveling of the oscillation laser light is hindered.

In this embodiment, two pairs of laser devices, ie, a first pair of laser devices and a second pair of laser devices, are used. However, the upper image 4Du of the first pair of laser devices is obtained. After the drawing is completed, the first pair of laser devices can be adjusted again to draw the image 4 of the lower image 4Dd in the same manner.

In the vitreous decorative article according to the present invention, the bubbles function as a decorative component, a function as an object of a different refractive index present in an optical medium through which a laser beam passes,
It has properties such as physical and chemical inhomogeneity near the bubble wall in the vitreous material.

In the present embodiment, a part of the image 4 is configured based on the above-described feature, that is, as a chalcedony to which the dragon 4D of the image 4 is added. In addition, bubble 3
Causes the oscillation laser beams 5L, 6L, 7L, and 8L to be scattered, so that the oscillation laser beams 5L, 6L, 7L, and 8L are
It is not possible to form a focal point on the opposite side of the bubble 3 through a portion such as the bubble 3 having a refractive index discontinuously different from the surrounding quartz glass 2 portion. Therefore, in order to form the image 4 in which the bubbles 3 are worked, the oscillation laser beams 5L, 6L,
The position at which 7L and 8L are incident becomes important.
In order to draw a richly decorative image 4 utilizing the laser light 2, it is necessary to appropriately consider the position of a plane formed on the quartz glass 2 so that the oscillation laser beams 5L, 6L, 7L, and 8L are appropriately incident.

The vitreous decorative article 1 having the above-described configuration and manufactured, for example, when illuminated from the outside,
The bubble 3 as a chalcedony constituting a part of the image 4 emits a unique light, and gives a viewer who has a completely different aesthetic appearance than the chalcedony simply drawn by the oscillation laser light.

Next, another embodiment of a vitreous ornament according to the present invention and a method for producing the same will be described with reference to the accompanying drawings.

As shown in FIG. 3, the vitreous decorative article 10 according to the present invention is, for example, a quartz body in which one of two opposing surfaces of a polished rectangular parallelepiped is formed as a convex surface 11A and the other surface is formed as a concave surface 11B.

Further, two sets of laser devices described above are prepared.

As shown in FIG. 5, the condensing lenses 15R, 16R of the laser means 15, 16 of the first pair of laser devices.
Is adjusted to focus the oscillation laser beams 15L and 16L on the bubble 1
3

The plurality of rings 14A of Saturn 14S
Since the laser light is distributed in the same plane around 3, the oscillation laser beams 15 </ b> L and 16 </ b> L are irradiated from the upper plane of the quartz glass 11.

On the other hand, the condenser lenses 17R and 18R of the laser means of the second pair of laser devices are adjusted so that the oscillating laser beams 17L and 18L are focused on the bubble wall of the bubble 12.

Thereafter, in the same manner as described in the above-described embodiment, a computer in which the shapes of the images 14 of the plurality of rings 14A of Saturn 14S and the plurality of tails 14T of the comet 14C are programmed in advance is used. The one pair of laser devices and the second pair of laser devices are controlled to draw Saturn 14S and comet 14C.
