FAQs

Can I put the lid in the oven?

Are the materials BPA-free?

What is the best way to clean the seals?

Remove the seals from the lid and wash them by hand in warm soapy water, then rinse and dry thoroughly before replacing.

Can I store liquids like soup in these?

Yes, the airtight and leak-proof design is suitable for liquids, provided the vacuum seal is engaged correctly.

Troubleshooting

The vacuum seal does not seem to hold.

Check the silicone gasket for debris or damage, and ensure it is pressed firmly into its groove before engaging the push-button.

Lid is difficult to remove after vacuum sealing.

Ensure the vacuum release valve or push-button is fully activated to equalize the pressure before attempting to lift the lid.

Setup, Compatibility & Care

To ensure the longevity of your Black + Blum Glass Food Containers, always inspect the silicone seal before closing to ensure it is clean and free of debris. When using in the oven or air fryer, remove the lid entirely, as only the borosilicate glass base is heat-resistant for those specific applications. For cleaning, the glass bases are dishwasher safe; however, removing the silicone gasket periodically is recommended to prevent food buildup. Avoid using abrasive sponges on the glass to prevent surface scratches that could weaken the material over time. When storing in a freezer, leave a small amount of "headroom" at the top if filling with liquids, as the expansion of frozen food can exert pressure on the glass.
