It's moldable and holds its shape well, which makes it great for your desert gold millipedes as it allows them to create stable burrows. The clay typically dries hard, helping maintain the structure of the burrows while also being easy to remoisten and reshape as needed.
For a cheaper alternative, some people use a mix of natural clay (like bentonite) with sand and soil, which can be similar in texture and functionality but at a lower cost. Just ensure the natural clay is free of chemicals and safe for your pets.
Interestingly, this concept of mixing materials for optimized functionality is somewhat similar to details about bridges construction, where a mix of materials is used to ensure stability and longevity.
