What You’ll Need for This Method
Before you begin, make sure you have everything ready. Fortunately, the materials are simple:
- An empty glass bottle (any wine or beer bottle will do!).
- A quality glass cutter.
- Access to hot and cold water.
- Two containers for the water.
- Sandpaper for finishing the edge.
- Protective gloves (safety first!).
Step 1: Score the Bottle with a Glass Cutter
First, you need to create a score line. Using a tungsten carbide (Widia) glass cutter, carefully draw a straight and even line around the bottle. This mark is crucial because it will guide the cut, so be sure it’s a single, continuous line.
Step 2: Alternate Hot and Cold Water
Here comes the exciting part of learning how to cut glass bottles with water. Fill one container with very hot water and another with cold water.
First, carefully pour the hot water directly over the score line, rotating the bottle for about 30 seconds. Then, immediately submerge the same area in the cold water. You should hear a faint cracking sound. If it doesn’t separate on the first try, simply repeat the process. The thermal shock will cause the glass to break cleanly along your line.

Step 3: Smooth the Edges for Safety
Once the bottle separates, the new edge will be sharp. Therefore, the final step is to polish it using sandpaper. This ensures a smooth, safe finish for your new creation. For a truly professional result, we recommend using our specialized diamond sandpaper kits.
