Can You Laser Engrave Glass? A Complete Guide to Glass Compatibility with OMTech Laser Machines

Glass is a timeless, elegant material that finds its place in everything from home décor to personalised gifts and functional products. With the rise of DIY culture and small creative businesses in Australia, more people are asking: Can you use a laser engraver on glass? The answer is yes — and it’s easier than you might think.

OMTech will explore the compatibility of glass with different types of laser cutter machines, how to select the right engraving machine for your glass projects, tips for achieving clean results, and ideas for using laser-engraved glass in your home or business. Whether you’re crafting a one-off piece or adding glass to your list of laser projects, OMTech has the tools and expertise to help.

 

1. Is Glass Compatible with Laser Engraving Machines?

Yes — but with some important considerations. While glass is non-metallic and brittle, it responds well to certain types of laser engraving. The key is using a machine that can engrave the surface without cracking or shattering the material.

Best Laser Type for Glass:

• CO2 Laser Engravers: These are ideal for engraving glass. The wavelength of CO2 lasers is well absorbed by the glass surface, enabling precise and frosted-style markings without deep cuts.
• Fibre Laser Machines: Not suitable for glass. Fibre lasers operate at a wavelength that passes through glass rather than interacting with it, so they are best reserved for metals and plastics. For more on that, check out our fibre laser machines collection.

So, if you’re planning to work with glass, a CO2 laser cutter machine from OMTech is your best match.

 

2. Choosing the Right OMTech Laser Engraver for Glass

Not all CO2 laser machines are created equal. Your choice will depend on the size of your projects, the thickness of the glass, and whether you’re operating from a home workshop or a commercial space.

Recommended Models:

• Mid-Range CO2 Laser Engravers: These offer the perfect balance between power, size, and price — ideal for hobbyists and small businesses. View the full range here.
• OMTech Polar: A compact but powerful desktop CO2 laser that's excellent for smaller glass engraving tasks such as wine glasses, ornaments, and awards.

When engraving glass, what matters most is control and precision. CO2 lasers allow you to fine-tune power and speed settings to get that frosted effect without chipping the surface.

4. Laser Engraving Glass: Key Tips and Best Practices

Laser engraving glass comes with a learning curve, but with the right approach, it’s incredibly rewarding. Here are some best practices to get crisp, clean results:

Use Low Power and High Speed

Engraving with high power may crack the glass or cause chipping. Instead, use low power and high speed settings to gently etch the surface.

Use Masking Tape

Applying a layer of wet paper towel or masking tape to the surface can help reduce heat and prevent chipping. This also gives a more consistent frosted appearance.

Choose the Right Glass

Tempered glass is not ideal for laser engraving because it can shatter due to internal stresses. Float glass, borosilicate, and crystal glasses work best.

Clean Thoroughly

After engraving, use a damp cloth to remove any residue or dust. This ensures the final product looks clean and polished.

Practice on Test Pieces

Always test your settings on a scrap piece or small glass item before moving to your final project.

With a little experimentation, your laser engraver can become your go-to tool for producing beautiful and durable glass art.
