this container is dishwasher safe (top rack recommended). remove lid before placing in hot oven or microwave. as with any glass product or hot surface, please use common sense when heating, storing and handling. as with other glass products, avoid extreme temperature changes (freezer to oven, for example) that will crack the glass. handle with care when using as bakeware. the silicone sleeve adds protection, but does not guarantee against breakage.
