Can I put the Glass Lunch Pot Large in the microwave?
The only part of the Glass Lunch Pot Large that is NOT microwave-safe is the stainless steel lid, otherwise, the glass pot, wood fibre base and silicone lid can go in the microwave. The silicone lid makes splatter-proof heating easy, and to ensure it doesn’t get sucked into the pot while it’s being heated, lift the lid and push the tab detail inside the rim to create an air gap. Heat your glass lunch pot inside the wood fibre base, as it does not retain heat and therefore can be handled safely. Food should be heated for a maximum of 2 minutes at a time, stir and repeat if necessary.
Can I use the Glass Lunch Pot Large in the oven?
The only parts of the product which are oven-safe are the Borosilicate Glass Pot and silicone lid. However, you must ensure that the glass is room temperature before placing it in the oven as glass is susceptible to thermal shock (meaning a sudden change in temperature) - which would cause it to break. When the glass is removed from the oven, AVOID running under cold water or placing on a cold surface. DO NOT allow direct contact with flames or use it under the grill.
Can I put the Glass Lunch Pot Large in the dishwasher?
For optimal product maintenance, place the parts on the top rack of your dishwasher. Try to avoid placing the glass pot under cold water or on a cold surface if it’s hot from the dishwasher, as this may cause it to break.
Can I put the Glass Lunch Pot Large in the freezer?
You can place all parts in the freezer however, as liquids expand when frozen, ensure you leave a space and do not overfill. Ensure food has defrosted completely and has come to room temperature before reheating, DO NOT use the microwave or oven to defrost.
Is this product BPA and BPS free?
Yes, all parts, and all products at Black+Blum are BPS and BPA-free.
The stainless steel lid feels quite stiff sometimes, how can I fix this?
Simply wipe the inside of the lid with vegetable oil and let dry if you’re finding it gets stiff after using a few times. Always make sure the glass pot and silicone lid are INSIDE the wood fibre base before you attempt to shut it, as the stainless steel lid can get stuck when it’s empty.
What is the base made from?
It’s a mixture of 30% sustainably sourced PEFC wood fibre and polypropylene.
Do you sell replacement parts if anything breaks?
Yes, definitely. At Black+Blum we are all about conscious consumption, so we offer replacement parts on most of our products. Simply visit the REPLACEMENT PARTS section of our site to order what you need.
The silicone lid ensures a splatter free microwave and the tab on the side of the silicone lid ensures no heat vacuum forms when your lunch pot is heated.
Borosilicate glass is very strong, recyclable and stain resistant. Super high quality and lightweight.
Made from sustainably sourced 30% wood fibre and polypropylene, the base includes a silicone non-slip ring and will protect the glass from small drops. It also protects your hands when heating food.
Historically, reusable glass lunch boxes have been heavy and never completely leak proof, so we wanted to design something which solved both these problems, that would be the best on the market. We spent 3 years (and many iterations) developing this product, utilising lightweight and strong Borosilicate glass to bring our vision to life. The glass is protected with a wood fibre base and stainless steel lid, two materials that work and feel really nice together. It’s a modern design with a retro character that is completely unique to the market. It’s functional, compact and perfect for using on-the-go.
