Do you have a broken glass vase or want to add some pizazz to your next glass art project? With some extra preparation or specialized glue, you'll be able to complete those glass-based projects without any trouble at all and without making a sticky mess! This wikiHow article will teach you how to glue glass with ease!

Steps

Method 1 Method 1 of 2:

Repair a Fracture

Download Article

1. 1 Select a glue. You'll need a specialized glue made to bond with glass, or the glass will come apart again as soon as it is cleaned.[1]
   • Silicone based adhesives are transparent and strong once dry, but can be toxic.[2] Aquarium glues fall under this category.
   • Ultraviolet (UV) curing acrylic resins are excellent for repairing clear glass fragments that fit snugly together.[3] They require exposure to sunlight or a UV lamp to set.[4] Opaque or colored glass may block some of the UV light, causing a weaker bond.
   • If you are repairing an object that will be exposed to water, make sure the glue is waterproof. Most silicone adhesives and some UV resins are waterproof.
   • If you are repairing an object that will come into contact with food or drink, check that the glue used is made for this purpose. Some adhesives are toxic even when dry.
2. 2 Clean both pieces with soap and water. After cleaning, wipe each piece dry thoroughly with a clean cloth. The pieces will bond best if they are clean, dry, and oil-free.
   • Wear latex gloves while preparing and gluing the surfaces. This will prevent oil from your hands from rubbing off on the glass, and protect you from toxic or messy adhesives.
   • Difficult stains can be scrubbed off using steel wool.[5]

3. 3 Apply glue along one of the broken edges. You only need a small amount, but make sure the entire broken edge is covered. You only need to apply glue to one of the broken pieces.
4. 4 Press the two pieces together. Ensure the broken surfaces are aligned and hold in place for at least one minute.
5. 5 Allow the glue to set. This will take somewhere between a few minutes and 24 hours depending on the type and brand of glue. Even once it seems firm, avoid applying significant force for 24 hours.
   • UV curing adhesives require exposure to ultraviolet light. A few minutes in direct, bright sunlight or under a UV lamp should harden the glue. Allow more time for opaque glass or less intense sunlight.
   • Silicone based glues require several hours at least to set. They do not require sunlight and will set in most weather conditions (5%–95% humidity; 40º–100ºF=5º-40ºC).[6]
   • For large flat pieces of glass, fix them in place with a glass clamp or another clamp specialized for holding fragile objects. Avoid cracking the glass through over-tightening.
6. 6 Shave away any excess glue with a razor blade. Check in on the glass before it's done setting. Excess glue may have oozed out of the joint and begun to dry. Carefully shave away this excess glue with a razor blade and wipe the surrounding area clean.
   • Both UV and silicone glues will dry completely clear, so the fracture should be well concealed.

   It is not advisable to reuse broken glass. You might be able to glue it back together, but the glass loses its original qualities. It will not be as strong and stable as before. For safety reasons, avoid using broken glass for its original purpose.

Method 2 Method 2 of 2:

Decorate Glass

Download Article

1. 1 Decide on materials and glue. You could decorate a glass jar with fabric or paper cutouts, or make a 3D mosaic by placing ceramic or glass tiles over a flower vase. Each combination of two materials can only be bonded by specific glues.
   • Browse your hardware store or art supply store and read the glue labels to see which one is suitable for the materials you chose.
   • A glue that dries clear is preferable for most art projects.
2. 2 Prepare your materials. A few simple steps will quicken the decorating process and ensure that the glass bonds strongly.
   • Wash the glass thoroughly with soap and water.
   • Dry the glass with a clean paper towel.
   • Empty some glue into a plastic container. This will make it easy to apply with a paintbrush, and cause it to dry slightly for a useful tacky consistency.
3. 3 Paint a thin layer of glue over the object. Cover any areas you intend to decorate. Wipe off any excess blobs and wait for it to dry.[7]
   • The setting time for the glue varies depending on the type of glue used. In most cases 5-10 minutes should be enough.

   Choosing the perfect type of glue can make all the difference in your project. Different glues have different strengths, clarity, and drying times, so choose the one that will work best for you. Do you need a strong bond? Or is clarity after drying your top priority?

4. 4 Apply a second layer of glue to a small area. Once the first coat has dried, adding a small amount of glue to an area will make it wet and tacky, preventing your decorations from slipping.
   • Wait another 5-10 minutes for this to take effect.
5. 5 Attach your decorations to the prepared area. If they slide off, wait for the glue to dry a little more and try again.[8]
   • Apply, wait, and decorate each area in turn. Feel free to apply glue to a new area while you're still decorating the previous one.
6. 6 Add a last layer of glue over your decorations to seal them in. Let dry.
7. 7 Spray with a sealant to ensure durability and water resistance. Let dry for 15 minutes.
8. 8 Wipe off excess glue and let dry. Allow the glue to stand 24 hours before handling the object roughly, then enjoy your new decoration!
9. 9 Finished!

• Question What is annealing, and what does it do to a glass? Bicycle Glass Glassblowing Experts Bicycle Glass Co. was founded in 2016 by David Royce and Michael Boyd, two professional glass experts. Bicycle Glass is primarily a lighting company, committed to quality, sustainability, and affordability. All Bicycle Glass products are made of high-quality, recycled glass and are hand-blown by a dedicated team of artisans. The studio is committed to reducing its carbon footprint by conserving energy in all of its production. Using renewable wind energy to offset all electricity usage, the studio is actively working toward the goal of carbon neutrality. Bicycle Glass believes that high-quality, handmade glass products should be within reach for everyone. Bicycle Glass Glassblowing Experts Expert Answer The appropriate annealing temperatures ensure that the glass can remain stationary without undergoing deformation over time. If the temperature is excessively high, such as at 1200 degrees for 10 minutes, the glass may appear stable initially but could gradually surpass the annealing point if left for an extended period, say, over 10 hours. The annealing point is the temperature at which the glass ceases to move and can theoretically remain in that state indefinitely. Below the annealing point, typically around the 700-degree range (though this can vary based on the specific glass composition), there exists a crucial stage known as the strain point. Glass must undergo a slow transition between the annealing and strain points, and subsequently, it needs to move from the strain point down to room temperature through another gradual process, although this is usually shorter in duration. Proper annealing, ensuring no movement while cooling, generally requires around a day, aligning with a meticulous understanding of these temperature transitions. Thanks! We're glad this was helpful.

• Question How can I glue handles on a wine glass? Community Answer You glue handles on a wine glass with glue. There is Gorilla Super Glue, Loctite Glass Super Glue, or E-6000 2oz Clear Industrial Strength Glue. These basic glues are fine but the best adhesive or bonding agent for glass is known as an epoxy. Epoxy is made to use for almost any surface. Thanks! We're glad this was helpful. Thank you for your feedback.

• Question Can you use a hot glue on glass? Community Answer Yes, but a low-temp hot glue gun would be safer than a high-temp hot glue gun. If the glue is too hot, you could break the glass. Thanks!
