Tempered Glass
Toughened safety glass that’s built to handle more. Heat-treated for strength, it’s around 4–5 times stronger than standard glass and shatters into small, safer pieces if it ever breaks. A solid, dependable choice for tables, shelves, splashbacks, partitions and more. Multiple thicknesses, made to measure and ready to fit where you need it.
Tempered Glass FAQs
What exactly is tempered glass and how is it made?
Tempered glass is a type of safety glass that’s been heat-treated to toughen it up. Heating glass to around 620°C, then cooling it quickly, creates a strong outer shell and puts the inside under tension. The result? Glass that’s four to five times stronger than standard varieties. If it does break, it crumbles into blunt bits instead of dangerous shards - helpful if you’re a bit clumsy in the kitchen.
Can tempered glass be cut or drilled after it’s been made?
No, tempered glass cannot be cut or drilled once it’s been toughened. The toughening process locks in internal stresses, so altering it afterwards makes the whole thing shatter. Any cutting or shaping needs to happen beforehand. If you’re planning a custom fit, double-check your measurements before it goes into the kiln.
Is tempered glass heat-resistant and safe for kitchen use?
Yes, tempered glass is heat-resistant and safe for kitchen use. It can handle temperatures up to 250°C and sudden heat changes, making it spot on for oven doors, hobs, and splashbacks. Some versions are lab-tested and even come with a warranty for peace of mind. Have a look at our durable, heat-resistant kitchenware for clever long-life picks.
How can I tell if a piece of glass is tempered?
To tell if glass is tempered, check for an etched safety stamp in the corner (UK glass usually shows BS EN 12150). Another cheeky trick - pop on polarised sunglasses under bright light and look for faint stripes or wavy patterns. These stress marks aren’t visible to the naked eye but show the glass has been toughened.
What are the longest-lasting tempered glass options available?
The longest-lasting tempered glass options are those with scratch-resistant coatings, high heat tolerance and trusted certifications like BS EN 12150. While it can’t be repaired if broken, tempered glass is designed to hold up for decades of daily use. We only choose glass that meets strict endurance tests - see how we research and select durable products.
How should I clean and care for tempered glass to keep it looking new?
To keep tempered glass looking sharp, use a soft cloth with mild detergent or a vinegar and water mix. Skip anything abrasive - it can scratch the surface. Dry it off after cleaning to avoid streaks. Regular gentle upkeep keeps the glass clear and gleaming, and there are more handy hints in our Product Care and Repair hub.
Is tempered glass recyclable or environmentally friendly to dispose of?
Tempered glass is recyclable, but not through your usual curbside bin. Its internal stress means it needs specialist processing. Try your local recycling centre - they may point you to a facility that handles things like car or building glass. Despite its landfill woes, tempered glass is inert and built to last, which makes it a more planet-friendly option over time.
