FAQ: Borosilicate Glass – Strong, Safe and Built to Last
What makes borosilicate glass different from regular glass?
Borosilicate glass is different from regular glass because it contains boron trioxide, making it tough and resistant to sudden temperature changes. It won’t shatter when switching from hot to cold, which sets it apart from soda-lime glass found in windows and jars. It’s also scratch-resistant, odour-free, and keeps its clarity over time. That’s why it’s the glass of choice for both your roast dinner dish and your science beakers. In short, it's more than just a pretty glass.
Is borosilicate glass safe to use in the oven or microwave?
Yes, borosilicate glass is safe to use in the oven or microwave - it can take the heat. It handles up to 400°C and shrugs off temperature swings, so it’s freezer-to-oven friendly. Just don’t pop it on a direct flame or under the grill. As ever, check the manufacturer's advice first, but most kitchen uses are well within its wheelhouse.
How do you clean and care for borosilicate glass properly?
To clean borosilicate glass, just use warm soapy water or chuck it in the dishwasher - it’s not fussy. Avoid harsh scouring pads and knocks to keep it chip-free. Got some baked-on gunk? A soak with warm water and baking soda usually does the trick. With a little care, it stays gleaming and strong. For more upkeep tips, see our Product Care & Repair hub.
Are borosilicate containers dishwasher and freezer safe?
Yes, borosilicate containers are both dishwasher and freezer safe - they’re built for extremes. They won’t crack in the cold or dull in the dishwasher, even after years of use. Perfect for batch cooks and leftovers alike. Some brands even offer lifetime guarantees, which says it all, really.
Which are the most durable borosilicate glass products?
The most durable borosilicate glass products include thick-walled dishes, reinforced measuring jugs and storage containers with long-lasting lids. These resist chipping, cracking, and thermal shock, making them ideal for daily use. Look out for lifetime guarantees and repairable parts - they’re a solid indicator of a well-made bit of kit. Explore our food storage collection for extra-sturdy options.
Can borosilicate glass be recycled or reused sustainably?
Yes, borosilicate glass can be reused and recycled sustainably, though it needs a separate recycling stream due to its high melting point. Not all local centres take it, so check first. That said, it lasts for absolute yonks, so you might be reusing that lasagne dish well into retirement. Repurposing is easy - use containers for storage and say cheerio to single-use plastic.
Does borosilicate glass contain any harmful chemicals?
No, borosilicate glass doesn’t contain harmful chemicals like BPA or lead. It’s non-porous and chemically stable, so nothing nasty leaches into your food or drink - even when it’s piping hot. That’s why it’s trusted everywhere from home kitchens to science labs. Safe, sturdy, and forever unflappable.
