Ceramics Laser Marking FAQs<\/h2>\n<\/div>\n<details>\n<summary>Can laser marking crack glass?<\/summary>\n<p>Yes, it can if heat, focus, residual stress or part support are not controlled. Tempered, laminated, coated and stressed glass should be tested in final condition with defined crack and strength criteria.<\/p>\n<\/details>\n<details>\n<summary>Which laser is used for glass marking?<\/summary>\n<p>CO2, UV, green and specialized internal systems can be relevant depending on glass type, coating, target effect and mark position. The right route should be proven with the actual sample.<\/p>\n<\/details>\n<details>\n<summary>Can the same machine mark ceramics and glass?<\/summary>\n<p>Some configurations can process selected glass and ceramic tasks, but the stable process window, optics, fixture and inspection requirements may differ significantly.<\/p>\n<\/details>\n<details>\n<summary>Is internal engraving the same as glass surface marking?<\/summary>\n<p>No. Internal or subsurface effects require dedicated optics, controlled focus inside transparent material and confirmed equipment scope. Do not assume that a normal glass surface marking setup can perform internal engraving.<\/p>\n<\/details>\n<details>\n<summary>What samples should I send?<\/summary>\n<p>Send the final material or part, including glass type, crystal type, ceramic grade, temper, coating, glaze, thickness, mark side, target effect, artwork, quality limits, durability tests and safety information.<\/p>\n<\/details>\n<\/div>\n<\/section><section class=\"zr-cta\">\n<div class=\"zr-container\">\n<div class=\"zr-eyebrow\">Prepare a Useful Test<\/div>\n<h2>Send the Actual Glass, Crystal or Ceramic Part and the Required Mark Effect<\/h2>\n<p>Include the final substrate, coating or glaze, thickness, stress or temper state, mark side, internal or surface target, artwork or code, quality limits, durability requirement, cycle target, fixture constraints and any SDS or safety notes.
