Hard surfaces such as metals, glass, ceramics, porcelain, crystal, plastics, marble, and granite can be safely and permanently marked. Metals can generally be marked with black or dark grey; while other surfaces can be marked in a number of available colors. Metals that can be marked include tool steel, stainless steel, most aluminum, brass, copper, tin, pewter, most silver, chrome, titanium, tungsten carbide and lead-coated steel. Most aluminum is suitable for marking, except for shiny, high-polish alloys.

Colored marks on challenging substrates
TherMark offers several products specially engineered for optimal laser marking of glass and ceramics. These products are scientifically formulated to create a permanent chemical bond to glass or ceramic surfaces.

Marking glass or ceramic with traditional methods is a significant challenge. Current marking methods tend to produce low-contrast gray marks. Chemical etching processes can be time consuming and involve using highly toxic materials. Direct marks with a CO2 laser are made by creating ‘micro-fractures” which frost the glass but can compromise the strength of the substrate.
