Query: Beaker breaks too easily under normal use

Love the product, but I have now broken two beakers by simply pouring hot water into the beaker. In both cases, they cracked (and then exploded) leaving a most interesting mess to clean up.Upon closer inspection of the beaker, it is clear that it is made with ZERO extra material and heft. This makes sense for the manufacturer from a materials and shipping standpoint, but it will certainly affect durability and value for the consumer.Now that I'm considering a THIRD replacement, I'm wondering what other options are available.
