glasscutting

Glasscutting refers to the process of shaping or dividing glass using various tools and techniques. The most common method involves scoring the glass with a sharp, hard object, typically a diamond-tipped or carbide wheel cutter. This creates a controlled line of stress on the glass surface. Applying pressure along this score line, either by snapping the glass over an edge or using specialized pliers, causes it to break cleanly.

Different types of glass require specific cutting approaches. For instance, float glass, commonly used in windows and mirrors, is relatively easy to cut with a standard glass cutter. Thicker or tempered glass, however, may necessitate different tools or pre-heating techniques to prevent shattering. Specialty glass, such as stained glass or optical glass, often involves more intricate cutting methods to achieve precise shapes and avoid damage.

Beyond simple straight cuts, glasscutting encompasses techniques like cutting curves and circles, often achieved with specialized jigs and templates. For decorative purposes, engraving or sandblasting can be used to create intricate designs on the glass surface, which can be considered a form of artistic glasscutting. The practice is essential in industries ranging from construction and automotive manufacturing to art and scientific instrument production. Safety precautions, including wearing protective eyewear and gloves, are crucial due to the sharp edges of cut glass.
