GLASS LUNCH POT LARGE, 12cm x 12cm x 9.5cm

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.

Heat your glass lunch pot inside the wood fibre base, as it does not retain heat and therefore can be handled safely.

We do not recommend placing the metal lid directly onto the silicone lid when the contents are hot.

Can I use the Glass Lunch Pot Large in the oven?

Yes, all parts, and all products at Black+Blum are BPS and BPA-free.

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.

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.

100% leakproof.

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.
