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.
