Borosilicate – the clear beauty

Borosilicate glass, first developed in the late 19th century by German chemist Otto Schott, redefined the potential of glass. With its remarkable heat resistance, chemical stability, transparency, and non-reactive nature, borosilicate glass surpasses traditional soda glass in both functionality and aesthetics. Its ability to endure extreme temperatures has made it a favourite among designers and makers in fields ranging from laboratory equipment to fine art. Plus, its recyclable nature brings an added layer of sustainability, aligning perfectly with modern design principles.

The process of shaping borosilicate glass on a lathe is an art form in itself, blending precision, heat, and craftsmanship. It begins with a carefully chosen borosilicate rod, its color, diameter, and length selected for the intended design. Mounted securely on the lathe, the glass is rotated at a controlled speed. Moulds are made of Tungsten carbide tools, known for their strength. The slow rotation allows the artists to guide the glass effortlessly, shaping it into tubes, rods, or complex, intricate forms.

As the glass heats up, controlled air is introduced through pipes, allowing the material to expand and become more malleable. This delicate balance between heat and precision allows for an almost poetic interaction with the lathe, transforming the glass into striking shapes. Once the shaping process is complete, the glass is polished to remove any imperfections and enhance its natural clarity, turning it into a piece that is both visually captivating and practical.

Safety is essential throughout this delicate process, with protective gear worn by the craftsman to prevent any risk of glass shattering.

The precision of lathe work combined with the designer’s creativity allows for the creation of pieces that are not only practical but also visually striking, making lathe-worked borosilicate glass highly sought after in both industrial and artistic realms.

For designers, borosilicate glass offers endless possibilities but in circular sections. Its durability, versatility, and ability to be moulded with precision enable the creation of functional works of art. Whether you’re crafting a lighting fixture that evokes elegance or a scientific instrument with sleek, minimalist lines, borosilicate glass on the lathe allows for the perfect balance of form, function, and sustainability.
