摘要： An undercoating is deposited on a glass workpiece and an overcoating is applied upon the undercoating. Then a plurality of related marks is recessed through the overcoating, thereby producing the novel workpiece. Each of the undercoating and overcoating is comprised of pigment particles and an alkali silicate binder. The alkali silicate binder of at least one coating, and preferably both the undercoating and the overcoating, consists essentially of a mixture of sodium silicate, potassium silicate and lithium silicate. The coatings are made from aqueous suspensions of pigment particles, dissolved sodium silicate, dissolved potassium silicate and lithium-stabilized silica sol.

摘要： A dark-colored undercoating is deposited on a desired surface area of a glass workpiece, and a light-colored overcoating is applied upon the undercoating, each coating being dried in less than about 60 seconds. Then a plurality of related marks is recessed through the overcoating by ablation, as with a laser beam. Each of the undercoating and the overcoating is comprised of pigment particles and an alkali silicate binder. Unlike the prior practice, the undercoating contains an operative proportion of mica particles, and the overcoating is essentially free from mica.

摘要翻译： 将深色底涂层沉积在玻璃工件的所需表面区域上，并且在底涂层上施加浅色外涂层，每个涂层在少于约60秒内干燥。 然后，与激光束一样，多个相关标记通过消融通过外涂凹陷。 底漆和外涂层均由颜料颗粒和碱性硅酸盐粘合剂组成。 与现有实践不同，底涂层含有云母颗粒的有效比例，并且外涂层基本上不含云母。
