how to cut glass tile When you cut glass tile, you have to be careful since it can break or shatter more easily than stone or ceramic tiles. It is also more prone to jagged edges, and it’s easier for imperfections to show after a cut has been made, especially if your tile is colored on the back and clear throughout the rest.

Where glass tiles differ from ceramic or stone, however, is the unique styles they can come in. No matter the color, shape, or size you want, you can find a glass tile to match the image in your mind. There are many things it can be used for in your home aside from a kitchen backsplash.

These tiles are perfect for a shower tile installation, as they’re extremely water-resistant. They’re even great for when you’re learning how to install tile backsplash.

There are more benefits, too. Instead of giving up on the idea of glass tile due to its difficulty to cut, though, we’re here to help you learn how to make it work for you. Read on to learn how to cut glass tile.

What Makes It Appealing?

Glass has actually been used as material for mosaics in churches for a long time. Think of old stained glass windows and you’ll understand exactly what we mean. it’s been a staple for art pieces throughout history and now, it’s been developed into a form of ceramic and has found its way into our homes, and especially into our kitchens.

If you’re new to the world of glass tile, you might not quite understand what makes it so appealing to homeowners nowadays. If something can shatter so easily, why wouldn’t you want to build with a different material?

Well, have you ever added a mirror to your space and felt like the room got bigger? That’s because the light was bouncing off the mirror and reflecting into different parts of the room. The mirror made everything in the room seem bigger and brighter, and glass tile has a similar effect.

It’s also easy to arrange into specific patterns and it can come in many different shapes, styles, and colors. Like we talked about earlier, cutting it is a different story. What materials do you need for that, though?

What Tools Do You Need?

There are actually 4 different methods you can use to cut your tile. The different tools you would need for each method include:

  • Glass cutter
  • Wet saw
  • Manual tile cutter
  • Wheeled mosaic nippers

Each tool comes with its own unique method for cutting, as well as other materials you’re going to need to gather.

Cut Glass Tile with a Wet Saw

how to cut glass tile Cutting glass tile with a wet saw is the most expensive method, but it’s also the easiest to rent out if you don’t want to spend money on it. You can rent a manual cutter as well, but it’s a less popular rental option. While electrical tile sawing tools range from $100 to $1,000, you can often rent the same thing for $50 a day. 

The other materials, besides the wet saw, include:

    • Washable marker
    • Washcloth
    • Rubber gloves
    • Safety glasses
    • Auditory protectors
    • Rubbing stone

You are going to start with measuring the tile that must be cut. From there, use your washable marker to draw a cutting guideline across the tile. Do not worry, you will be able to wipe this away with your washcloth later.

Time to Pull Out the Saw

Once you have got your tiles marked and ready to go, it is time to pull on your rubber gloves and start the wet saw up. You should allow it to run for 15 seconds so the blade gets nice and wet. When water is freely flowing over the blade, you are good to begin your cuts.

Once your cuts have been made, power down the saw and you are good to start your install.

Finally, with the rubbing stone, carefully smooth out your cuts and wipe away glass shavings. 

Manually Score and Cut Glass Tiles

Before wet saws, there was manual tile scoring. While it can result in uneven or jagged cuts, it is a faster cutting method and it is great for smaller or customizable glass tile cuts.

Glass scoring wheels are particularly inexpensive and easy to buy. They are very small and portable, which can be a big benefit over wet saws, plus they are easier to store away once you’re done using them. You will also need a pair of grozing pliers to work in tandem with this tool. Once you have them both, it is smart to practice with a few sample pieces before testing your skills on the real thing. Besides that, you’ll also need:

  • Washable marker
  • Straight edge
  • Rubbing stone
  • Washcloth

Start with marking your cuts, and then score one side of the tile. Place the scoring wheel at the far end of the tile and then pull the wheel towards you. You should press firmly enough to hear a cracking sound as the wheel rolls.

Once you have done that, take your grozing pliers and snap off the piece you want to break off. Be sure to pull downwards when you break the tile. From there, use your rubbing stone to smooth any edges before installation.

Using a Manual Tile Cutter 

Since the machine cuts and scores, manual tile cutters are far more efficient than a scoring wheel and pliers.

To use a manual tile cutter, which often comes with a scoring wheel included, you are going to need the same tools you needed to cut with a scoring wheel. 

Once you have measured your cuts, you are going to place the tile on the manual tile cutter’s cutting pad. Align the marked line with the manual tile cutter’s cutting guide.  From there, use the scoring handle to make the cut by pulling away from you. After you have cut, you are going to snap the tile manually, or with the machine’s pressure foot.  Smooth the edges, wipe away any marker, you are good to go!

Using Wheeled Mosaic Nippers

how to cut glass tile Most often, this tool is used to make small shapes for artistic glass tile designs.

This method is not as precise as any of the others, so it is going to require more practice to get the hang of it.

This tool is similar to a regular pair of pliers but has both upper and lower carbide wheels instead of a flat head. This cuts through glass more effectively. 

For this method, you are going to need:

  • Washable marker
  • Goggles
  • Washcloth

Besides that, you’re also going to need your wheeled mosaic nippers.

Making the Cuts

Start with drawing guidelines in your tile. It is recommended to mark the glass with a scoring wheel or manual cutter before nipping, and this technique is mostly used on small tiles.

To finish, take the rubbing stone, smooth out your cuts, wipe away glass shavings.

What About Cutting Curves? 

When you are laying tile around a curved object, like a wide air outlet or in a rounded shower stall or similar fixture, you are not going to be able to cut straight lines and expect it to fit. With the help of these tools, however, it can be achieved.

  • Scoring tool
  • Wet saw
  • Rubbing stone
  • Grozing pliers

Once you have gathered all of this, you are going to start by marking your cuts and cutting (freehand) with a scoring tool along your line. Work slowly and precisely here.

Then, you are going to make several straight cuts with your wet saw. Start from the portion of tile you are going to discard and move to the line you have already scored.

Once you have made all the straight cuts, you are going to snap off all the pieces from the portion you just cut. You can also use your grozing pliers for this part.  Finally, with the rubbing stone, smooth out your cuts, wipe away glass shavings, and get rid of the marker line. You are set to install.
