How to Use Nippers to Cut Glass Mosaic Tile

Step 1: Sketch Out the Shape or Design First

You can use nippers in very simple ways. If you want to cut out a shape or make a design, you first need to sketch it out with a marker on the glass.

Step 2: Follow the Lines You Drew

After you have your design sketched out, use the nippers to follow the lines you drew. Make sure to apply just the right amount of pressure on the tile, as too much pressure will result in a harsh and gritty sound.

Step 3: Snap the Tile into Two Pieces

If you want to break apart your piece of glass after scoring it, you can simply snap it into two pieces with your hands. Place your hands on either side of the scored line, with your thumbs pressing down, and apply an equal amount of pressure to each side.

Step 4: Use Other Tools if Necessary

If snapping the tile into two pieces does not work, you can use other tools such as pliers or thin wires to break it apart. Just be sure to wrap the ends of your tools in tape to prevent scratching the glass.

Another type of tool you can use is called a scoring tool. This is a tool with a carbide or diamond wheel on the end that is used to score, or scratch, the surface of the glass. This creates a broken line that helps you break the glass into small pieces.

Before you begin cutting the tile, it’s best to sketch out the shape or design that you want to create. This will make it easier for you to cut the tile along your desired lines.

Use a scoring tool to apply a score line on each side of your shape or design. This will help ensure that the glass is cut cleanly and evenly.

Step 3: Apply Pressure to Break the Tile Along the Score Line

Once you have applied a score line along each side of your shape or design, press down firmly on the tile in order to break it along your score line. If necessary, you can apply additional pressure using a hammer or other heavy object.

Step 4: Finish Cutting Any Smaller Pieces of Tile with Nippers

If needed, you can use nippers to finish cutting any smaller pieces of tile that are still remaining. Just be sure to wear eye protection and use caution when cutting glass, as this material can be sharp and dangerous if not handled properly.
