Do you have some special glassware, bottles, or jars you want to personalize with a permanent message or design? Etching glass is a fun way to customize your glass items, but many methods like glass paint pens and etching creams wear off over time. If you want your custom glass writing to last forever without fading or chipping, certain techniques like sandblasting, glass engraving, and combination methods allow you to permanently write or etch designs on glass surfaces.
With the right supplies and techniques, you can permanently label glassware, etch wedding glasses, customize tabletops, and more. Let’s get started!
Supplies You’ll Need
Glass writing requires patience and the right tools. Here are some supplies you’ll need:
- Glass marking pens – Specialized ceramic and porcelain paint pens are formulated for permanent glass application.
- Armour Etch – Cream containing hydrofluoric acid to etch designs into glass.
- Stencils – Apply lettering, designs, or patterns.
- Sandblasting tools – Sandblasters use compressed air to etch frosted areas.
- Adhesives – Glue foils, powders, or crushed glass.
Preparing the Glass Surface
Before permanently writing or etching on glass, it’s important to start with a pristine surface. Here are some tips for prep:
- Clean the glass thoroughly with glass cleaner or soap and warm water.
- Use a razor to remove any paint, lacquer or varnish.
- Lightly scuff the surface with 220 grit sandpaper.
- Wipe away debris and grease with alcohol or glass cleaner.
Proper prep ensures your permanent etchings or markings adhere directly to the glass for the best long-lasting results.
Choosing the Right Paints and Markers
Once your glass is prepped, it’s crucial to choose a high-quality paint or marker designed specifically for permanent glass application. We recommend:
- Marvy Decor Glass Writer Markers – Oil-based and fade resistant
- Krylon Glass Art Paint Markers – Vibrant colors and fast drying
- Armour Etch Glass Marking Pens – For etching fine details
Avoid cheap craft paints which can chip or peel. Test markers on a small area first before permanently writing on special pieces.
Employing Perfect Pen Strokes
Applying glass pens and markers takes a steady hand. Follow these tips:
- Shake the pen thoroughly before use.
- Apply consistent pressure as you write or draw.
- Let the ink fully dry between coats for crisp lines.
- Bake the glass after for added permanence.
- Practice first on scrap glass for best results.
Etching Cream Techniques
Another popular method for permanently writing on glass is using an etching cream containing hydrofluoric acid. Armour Etch is a trusted brand. To use:
- Clean and prep the glass surface.
- Apply your stencil design.
- Spread the etching cream smoothly over the stencil.
- Let the cream sit for 20 minutes up to 1 hour.
- Rinse away all residue under water.
- Dry and remove stencil gently.
Etching cream allows you to permanently write on glassware, mirrors, and tiles. Just be sure to closely follow all safety precautions when using the caustic chemical.
Choosing the Right Stencil
Using a stencil is key for neatly applying etching cream. Options include:
- Vinyl stencils – Reusable and easy to apply.
- Contact paper – For simple designs and text.
- Frisket paper – Thin paper ideal for detail work.
- Cricut stencils – Computer cut custom designs.
Ensure your stencil adheres fully before applying the etching cream for best results.
Employing Sandblasting
For permanent glass etching on a large scale, sandblasting is an ideal technique. It involves applying compressed air to blast tiny abrasives onto the glass surface. This frosts the glass to create a matte etched effect. To sandblast:
- Mask off any areas you don’t want blasted.
- Work in a well-ventilated area and wear a respirator.
- Move the nozzle across the surface smoothly and evenly.
- Start with lighter pressure and increase as needed.
- Clean away all dust when finished.
Sandblasting allows you to etch intricate patterns and designs that would be difficult by hand. It permanently writes on glass by abrasively removing material.
Choosing the Right Sandblasting Equipment
Having the proper sandblasting tools is essential. You’ll need:
- Compressor and hose – Consistent airflow is vital.
- Blasting nozzle – Control and directs the abrasive.
- Etching abrasive – Most commonly aluminum oxide.
- Dust collector – Keeps work area clean.
- Sandblasting cabinet – For safety and efficiency.
Consult an experienced sandblasting professional if you are unfamiliar with the equipment.
Combining Adhesives and Media
Another technique for permanently decorating glass combines adhesive media like glitter, foil, crushed glass, or powders. To use this method:
- Clean and prep the glass surface.
- Apply your stencil adhesive side down.
- Brush the medium firmly into the adhesive.
- Let it fully cure per adhesive directions.
- Spray with a clear acrylic sealer when dry.
This creates stunning dimensional effects. Experiment mixing media like foil flakes and glass beads for unique designs.
Choosing the Right Adhesive
The adhesive is critical for proper application and longevity when using media. Good options include:
- Craft glue – For attaching heavier materials.
- Double-sided tape – Foils and films adhere well.
- Gel glue – Won’t seep for fine details.
- Spray adhesive – Even coating and quick tack.
Test your adhesives first on a glass sample before permanently adhering to your final piece.
Finishing and Sealing
The final step when permanently writing on glass is applying a sealant or finish. This prevents the glass from wearing or fading over time. Consider:
- Glass etching sealers – Formulated for filling etched areas.
- Polyurethane – Tough and durable coating.
- Acrylic sprays – Crystal clear finish.
- Epoxy resin – Glossy coating good for small items.
Multiple thin coats allow finishes and sealers to fully cure for maximum durability. Avoid over-handling glass until fully cured.
Choosing the Right Sealer
With many sealant options available, choose one suitable for your project. Here are some tips:
- Aerosol sprays are easiest for overall coating.
- Brush-on sealers for more precise application.
- Solvent-based formulas provide a harder finish.
- Water-based sealers are lower odor.
- Test compatibility over etched/painted areas first.
Sealing is well worth the effort to permanently preserve your etched glass artwork or messages.
Troubleshooting Issues
Even when using proper techniques, you may encounter problems permanently writing on glass. Here are some common issues and fixes:
- Smudging – Ensure pens/paints are fully dry before additional coats.
- Uneven etching – Apply cream or blast nozzle evenly.
- Fading over time – Use a sealant and limit sun exposure.
- Paint not adhering – Properly clean and scuff the glass first.
- Bubbling – Slow down brush strokes; don’t overwork.
- Fixing mistakes – Gently sand away errors and re-etch.
Don’t become frustrated if results aren’t perfect immediately. Permanently writing on glass takes practice and patience.
Inspiring Glass Writing Projects
Now that you know how to permanently write on glass, here are some inspiring projects to try:
- Decorate and label glassware with names or monograms.
- Etch mirrors or tiles with meaningful quotes.
- Customize glass tabletops with your own designs.
- Personalize glass awards, plaques, and trophies.
- Create one-of-a-kind etched glass doors or panels.

Let your creativity run free! The possibilities for permanently writing on glass are endless.
As you can see, writing permanent messages on glass takes the right supplies and techniques, but the results are well worth the effort. Sandblasting, etching creams, adhesive media, and high-quality paint pens allow you to customize glassware, mirrors, tabletops, and more with designs and text that will remain crisp and vibrant for years to come.
We hope these tips give you the confidence to tackle your own glass etching projects. Just remember to properly prepare and seal the glass, work carefully, and don’t become discouraged with initial mishaps. With practice, you’ll be able to permanently write on glass with stunning results that stand the test of time.
