The limitation of hydrofluoric (HF) acid-etched effects for glass containers has been an enormous challenge for many years. Whilst it has been possible to simulate the frost-like appearance with a variety of coatings, it has not been possible to copy the total combination of smooth texture, quality feel and appearance, and durability that is typified by the "real thing." Ferro's R&D team have now met this challenge with the development of a new range of smooth feel,lead-free glass enamel etches, branded AcE. According to the US-based firm, AcE delivers a smooth texture and appearance that is indistinguishable from the real thing, with enhanced abrasion resistance compared to organic coatings. Ferro's formulation is based on a lead-free and cadmium-free glass, combined with a novel processing approach to create the final limitation etch enamel system.
