Picture frame with glass mat, and/or method of making the same
View Patent ↗Certain example embodiments of this invention relate to picture frames with glass mats that have patterns painted and/or screen printed thereon, and/or methods of making the same. The patterns may include large blocks of one or more solid colors, textures, images, logos, licensed images/designs, arbitrary designs, and/or the like, in different example instances. The painted glass matting materials of certain example embodiments have been found to provide unique, aesthetically appealing framing-related products that enhance the quality of the original art in desirable ways.
1. A method of making a frame, the method comprising:
screen printing a water-inclusive paint, directly or indirectly, on a major surface of a first glass substrate in a desired pattern in connection with a screen mesh that has at least 100 threads per inch and while maintaining an environment that has a relative humidity of at least 80% over and/or proximate to the screen mesh, the water-inclusive paint at least initially comprising 20-50 wt. % sodium silicate inclusive material(s) and 15-20% potassium silicate;
bonding the paint to the first glass substrate in the desired pattern by heating the first glass substrate to a first temperature of from 125-150 degrees C. and maintaining the first temperature to cause a majority of organic components in the paint to be driven off, and thereafter heating the first glass substrate to a peak temperature that is at least twice as high as the first temperature and that is no higher than 400 degrees C.; and
thereafter heat treating the first glass substrate, following the bonding, at a temperature of at least 580 degrees C., the paint remaining on the first glass substrate in the desired pattern and with a desired coloration following said heat treating.
2. The method of claim 1 , further comprising following said bonding and prior to said heat treating, cutting the first glass substrate to a desired size.
3. The method of claim 1 , wherein the first temperature is held for about 4 minutes.
4. The method of claim 1 , wherein the screen mesh has fewer than 200 threads per inch, the threads per inch being selected so as to achieve full flood.
5. The method of claim 1 , wherein the relative humidity in the environment is 90-95%.
6. The method of claim 1 , wherein the bonding fully cures the paint by driving off all organic components initially provided therein.
7. The method of claim 1 , wherein the paint, when fully cured, forms a colored pattern, and the first glass substrate has a surface stress less than about 250 psi in an area proximate the colored pattern.
8. The method of claim 7 , wherein the surface stress is less than about 150 psi in the area proximate the colored pattern.
9. The method of claim 1 , wherein the paint at least initially has an inorganic base.
10. The method of claim 1 , further comprising cutting a hole in the first glass substrate after said screen printing, the hole being sized and shaped to accommodate art or a picture of a predetermined size.
11. The method of claim 10 , further comprising finishing inner edges of the hole so as to provide a bevel, miter, notch, rib, and/or edge seam.
12. The method of claim 1 , further comprising laminating the first glass substrate to a cover substrate to form an assembly in which the screen printed major surface is provided as the second surface of the assembly.
13. The method of claim 12 , wherein the cover substrate is made of glass.
14. The method of claim 12 , wherein the cover substrate and/or the first glass substrate is/are heat treated.
15. The method of claim 12 , further comprising providing an antiglare and/or UV-blocking coating, directly or indirectly, on the first glass substrate and/or the cover substrate.
16. The method of claim 1 , further comprising affixing, using a plurality of mechanical fasteners, the first glass substrate to a cover substrate to form an assembly in which the screen printed major surface is provided as the second surface of the assembly.
17. The method of claim 1 , further comprising affixing the first glass substrate to a cover substrate using double-sided tape to form an assembly in which the screen printed major surface is provided as the second surface of the assembly.
18. The method of claim 1 , further comprising providing an antiglare and/or UV-blocking coating, directly or indirectly, on the first glass substrate, over the desired pattern.
