It is the block or tabular of 5～100mm that luminescent glass article of the present invention can be made thickness.When thickness during less than 5mm, because the luminous amount of substance that is present on the per unit area is less, therefore be difficult to obtain fully luminous intensity, when greater than 100mm, because internal modification increases, so physical strength reduces easily.And when the thickness of luminescent glass article became big, because the luminous amount of substance that is present on the per unit design area becomes many, so luminous intensity increased easily.Like this, tabular even glass article of the present invention is made, also can have high mechanical strength, and owing to have light transmission, therefore also can be used as with the designability is the daylighting member use of purpose.
In addition, luminescent glass article of the present invention is owing to be dispersed with the luminous material equably in glass, even therefore cut off, otch also has the surperficial identical outward appearance with other.Thus, also can cut off processing or engraving.
Below, the manufacture method of luminescent glass article of the present invention is described.
At first, with a plurality of glass particles and luminous material, and add binding agent and/or tinting material as required, mix equably, be filled in the resistivity against fire container that on internal surface, has formed alumina powder and/or ceramic fiber thin slice, by making luminescent glass article in 1～10 hour 800～1200 ℃ of following heat treated.
The median size of glass particle is 0.1～50mm, preferred 0.3～30mm, more preferably 0.5～10mm.When median size during greater than 50mm, owing to comprise big bubble easily in glass article, so physical strength just is compromised easily, and when less than 0.1mm, then manufacturing cost raises, and every 1cm
3Bubbles number easily more than 100.Glass particle can use has particle tabular, bar-shaped, the granulous shape.
In addition, also the piece of glass by will containing the luminous material or pottery can be pulverized the glass particle that get, with glass that does not contain the luminous material or ceramic mix particles.
