Toughened Glass: Enhancing Safety and Durability
At John Moncrieff Ltd, we've been producing toughened sight glasses for over a century. Toughening, also known as tempering, is a process that significantly enhances the strength and safety of glass. Compared to standard annealed glass, toughened glass is four times stronger and fractures into small, blunt pieces upon breakage, minimizing the risk of injury or equipment damage.
The Toughening Process:
Toughening involves heating the glass to near its melting point and then rapidly cooling the surface with cold air. This creates a compressive stress within the glass, effectively strengthening it four times compared to annealed glass. This compressive stress can be visualized using polarized light.

John Moncrieff's Commitment to Safety:
All of our standard sight and gauge glass products are manufactured using either borosilicate or soda lime glass, ensuring maximum safety in demanding environments. Our products are widely used in hazardous areas, such as oil rigs and chemical plants, where safety is paramount.
Benefits of Toughened Glass:
- Enhanced Safety: Four times stronger than annealed glass, reducing the risk of injury and equipment damage.
- Increased Durability: The added strength extends the lifespan of products, minimizing downtime due to maintenance.
- Cost-Effectiveness: Longer-lasting products can lead to reduced maintenance costs and improved operational efficiency.
Applications of Toughened Glass:
John Moncrieff Ltd offers a wide range of toughened glass products, including:
Circular Sight Glass Gauge Glass
- Reflex and Transparent Gauge Glasses
- Circular Sight Glasses
- Flat panels and other flat shapes
- Toughened glass tubing (a recent addition to our product line)
