Abstract
A method of providing an encodable layer on a glass object and on the resultant product. Said layer is formed by providing a paste containing glass frit, pigment and a binder, on the hot glass. As a result, the glass frit melts, causing the pigment to adhere to the glass object. The binder, which is used to render the paste spreadable, disappears from the mixture.
Claims3
A method of providing a glass object with label means for containing information, said label means comprising an encodable layer including glass and pigment, comprising providing a mixture of glass frit, pigment and a binder on a hot glass object, the glass object being sufficiently hot to melt the glass frit, which then crystallizes to thereby cause the pigment to adhere to the glass object, and to cause the binder to disappear, at least substantially, thereby forming said encodable layer.
