Preparation and Safety Guidelines

Tools Needed
  • Glass cutter
  • Running pliers
  • Wheeled glass nippers
  • Tweezers
  • Wood craft stick
  • Lexel (clear silicone adhesive)
  • Wax paper
  • Toothpick
  • Thinset mortar
  • Black oxide
  • Paper towels
Safety Guidelines
  • Always wear safety glasses to protect your eyes from flying glass fragments during cutting and tiling.
  • Use appropriate cutting tools (glass cutter, running pliers) and work on a stable, padded surface to prevent glass breakage and injury.
  • Handle glass pieces with care to avoid cuts. Wash hands thoroughly after handling glass.

Step-by-Step Instructions

  1. Substrate Preparation

    • Prepare the substrate (clean the glass votive)

  3. Adhesive Application (Method 1)

    • **Efficient Tiling Method:** Apply a thin layer of Lexel directly to the votive's surface. Place tesserae directly onto the adhesive. This method is faster but requires more skill and speed to prevent adhesive drying.

  4. Adhesive Application (Method 2)

    • Apply Lexel to the back of each tessera (butter the back). This is slower but minimizes mess and risk of adhesive showing between tiles.

  5. Tiling

    • Tile the entire surface of the votive, leaving the bottom clear

  6. Adhesive Curing

    • Allow the adhesive to cure for at least 48 hours.

  7. Grout Preparation

    • Mix thinset mortar with black oxide for the grout.

Tips

  • Use a clear adhesive for glass-on-glass mosaics to allow light to show through.
  • Use a fortified grout (like thinset) for glass substrates to prevent cracking and ensure adhesion.
  • Butter the back of each tessera with adhesive for a cleaner, less messy application and to reduce grout bleed.
  • Clean tools and hands with olive oil and paper towels to remove sticky silicone adhesive.
  • Maintain consistent, small grout lines for a clean finish, especially with small tesserae.

Common Mistakes to Avoid

1. Uneven Grout Lines

Reason: Inconsistent spacing between glass tiles leads to an unprofessional and uneven final look.
Solution: Use spacers to maintain consistent grout lines throughout the project.

2. Insufficient Grout

Reason: Not filling the gaps completely leaves the mosaic weak and susceptible to cracking, also affecting water resistance if used as a votive holder.
Solution: Ensure grout is fully pressed into the gaps between tiles and wipe away excess before it dries.

3. Cracked or Broken Tiles

Reason: Using damaged tiles will compromise the final look and structural integrity of the mosaic.
Solution: Carefully inspect tiles before adhering them, replacing any that are chipped or broken.

FAQs

What type of adhesive is best for glass-on-glass mosaics?
A strong, clear, and water-based adhesive specifically designed for glass and mosaics is recommended. Check the product label to ensure it's suitable for glass-on-glass applications and allows for a quick drying time.
Can I use any kind of glass tiles for this project?
While you can use various glass tiles, pre-cut, small, and relatively flat tiles will make the process much faster and easier. Avoid using extremely thick or irregularly shaped tiles.
How do I prevent the grout from clouding the glass?
Use a grout specifically designed for glass mosaics and apply it thinly and evenly. Immediately wipe away any excess grout with a damp sponge before it sets to maintain the clarity of the glass tiles.
