Thank you for taking the time to contact Rubbermaid. We’re sorry to hear about the cracking issue of your Rubbermaid Brilliance container. We'd be happy to help. Reheating implies the maximum short term service temperature of a Rubbermaid container is 165°F followed by a cool down period. Maintaining temperatures at 165°F or higher for more than 30 seconds is considered cooking, and is outside the intended use of these products. Also, this item is made of materials that are safe for freezer use. Please note that plastics are less flexible when cold or frozen and may break if dropped. Also note that water expands when frozen, so when filled to capacity the container could expand and crack and the wiper seal could be deflected. If you need further information you may contact us directly or using the contact form on our website. Have a great day.
