Hi Aj,
It’s great that you’re considering traditional materials in your design. Unfortunately, we couldn’t source the pricing for you. However, I found some resources that might provide you with more context on the usage and availability of clay in building materials and general pottery:
> Building Materials – a deep dive into the widely used construction materials for residential projects throughout Cambodia by Kambujaya
> Sourcing the Clay by Khmer Ceramics Fine Arts Centre
I hope this helps.
Regards,
Jean
