Abstract
This invention involves making a glass article or mirrored glass article by combining equal amounts of ammonium hydroxide, acetaldehyde, potassium nitrate, water glass and optionally silver nitrate, heating the mixture to 195.8.degree. C in a mold to expell hydrogen and acetaldehyde and optionally collecting the hydrogen and acetaldehyde in a reservoir.
Claims2
A method for making a glass article by heating ammonium hydroxide, acetaldehyde, potassium nitrate and water glass in solution form, each material being added in equal weights and put into a mold, said mold being made from a material that is not glass or of a metal that does not alloy with silver, heating the contents of the mold to a temperature ranging from 195.8.degree. centigrade to 300.degree. centigrade for a time sufficient to expell the hydrogen and the acetaldehyde in a reservoir.
