Setup, Compatibility & Care
To ensure the longevity of your Iwaki set, always remove the plastic lids before placing the glass containers into an oven or microwave. While the glass is oven-safe, avoid drastic temperature shocks, such as placing a cold glass container directly from the refrigerator into a preheated oven. When cleaning, place the glass bowls in the dishwasher, but hand-wash the lids to prevent warping or degradation of the seal. Store the containers in a cool, dry place and stack them carefully to avoid chips or cracks in the glass.
