How to Cut Glass
Time Required: Under 2 hours
Cutting glass is a delicate and tedious task easily performed with the right set of tools and safety in mind. If you’re planning a DIY craft or repair project that requires a specific shape or size, cutting it yourself can save time and money.
This guide will explain how to cut a glass sheet and thick glass materials at home.
Safety Tip: Practice the following steps on a scrap piece of glass before cutting the project.
- Choose an area with a large and flat surface. If the surface is solid, lay down something soft like a mat or old rug underneath the material to be cut to avoid surface damage.
- The best space to perform the project should be easy to clean and clear of pets and small children as an additional safety precaution.
There are different types and thicknesses of glass and sheets that can be used for indoor or outdoor projects.
Acrylic and plastic sheets are a protective surface typically used over shelves and table tops, as well as doors and windows.
Polycarbonate sheets are ideal for protection purposes and are 250 times stronger than glass.
Glass is used for installation or repair on door and window inserts, picture frames and craft projects.
- Use glass cleaner and a cutting rag to wipe down the surface of the material you are cutting, focusing on the areas where you plan to make cuts. If the material isn’t clean, it can affect the quality of the cut and make it more difficult to break through the surface.
- Let the material surface dry completely before moving on to the next step.
- Place the cutter on the surface of the material at the mark.
- Apply pressure while keeping the cutter slightly angled and tilted towards you.
- Slowly move the cutter across the surface in a slow and controlled motion until you’ve reached the end and have finished scoring.
- Repeat as needed.
- Use the head of the glass cutter to elevate the glass.
- Firmly hold the material on both sides of the cut.
- Apply pressure and break it apart as if you were opening the spine of a book.
- If it doesn’t break through completely to the other side, apply more pressure and lightly twist your hands to encourage the split.
