Pottery urns are surprisingly durable. Once the clay has been fired, it is hard and strong and can last for thousands of years -- as we know from ceramic vessels that date back to time periods such as the Han Dynasty in China, the Mayans, and the Greeks. We have shipped hundreds of ceramic urns safely to our customers. Once in your home or a columbarium, we do recommend that you place it in a secure spot to keep it safe from a long fall to a hard floor, etc.
