Inkcups Now says the ink accepts two different hardeners and has been very successful with stainless-steel travel mugs, metal pens, glass tumblers, mint and candy tins, light bulbs, and carabineers. The ink cures at temperatures below 180°F (82°C) and is reportedly easy to process and has a long pot life. The Sapphire CG series is a two-component ink and is available in 21 standard colors. The ink comes with a 12-color mixing system and a free formulation guide for generating Pantone colors.
