This 3-pack of large glass loaf pans measures 10.6 inches wide by 5.5 inches deep by 2.8 inches high each, crafted from high-borosilicate transparent glass that withstands temperatures up to 500 degrees Fahrenheit with even heat distribution to prevent burned spots. The material is safe for preheated ovens, microwaves, freezers, and top-rack dishwashers, making it a healthier chemical-free option that will not warp or absorb odors, tastes, or pigments from food. Each pan includes a grey BPA-free airtight lid that snaps on securely for leak-proof storage directly after oven or microwave use, though the plastic lids themselves are not oven or microwave safe. The multi-purpose design integrates baking, serving, freezing, and reheating for bread, meatloaf, cakes, baked casseroles, pasta, and ice cream terrines, with a recommended 25-degree oven temperature reduction when using glass. Ergonomic handles provide an easy grip for transport from oven to table, while the transparent body allows you to monitor baking progress in real time and stores compactly when not in use.
