Making a Mosaic with Broken Glass

Mosaic art from scrap glass

Creating a mosaic from broken glass is a great way to use broken and scrap glass into beautiful art. Here’s a step-by-step guide to get you started.

1. Gather your materials and tools

• 
  Broken Glass – gather pieces in various colors and shapes
  
• A base  – Choose a sturdy base like a wooden board, tile, or glass
• Adhesive – Use an adhesive designed for glass AND your base material
• Grout – Any color you like!
• Tweezers – especially you you're using small pieces
• Putty Knife or other flat tool – For spreading grout
• Sponge – For wiping away excess grout
• Safety Glasses – to protect your eyes
• Glass Cutter (Optional) – For precise shaping
• Hammer and Towel (Optional) – For breaking larger pieces

2. Prepare your work 

• Clean and dry your base.  If using wood or another porous surface, apply a sealant to protect it from moisture.
• If you need to break or cut glass, safety first! Glasses, gloves, and towels are all helpful.
• Breaking Techniques:
• Towel – Wrap your glass in a towel and use a hammer to break it into smaller pieces.
• Glass Cutter – Score the glass and break it along the scored line for more control.
• Mosaic nippers - Made for mosaic tile shaping.

3. Get creative 

• Arrange the glass pieces before gluing and snap a picture to use as your reference.
• Spread a thin layer of adhesive on your base.
• Working in sections, apply a small amount of adhesive to the back of each piece and press in place with light pressure.
• Allow to dry.  Dry time will vary; check the label for details.  

4. Finish your mosaic

• Apply your grout, following the package instructions – Spread it evenly, filling all gaps.
• Use a damp sponge to clean away the excess surface grout.
• Allow the grout to set before handling your mosaic. Check your product label for specifics. 
• Proudly display your masterpiece! 

Whether you frame it, use it as a tabletop, or turn it into wall art, your one-of-a-kind piece will add personality and color to any space.
