Claim:
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.
