Dear listers: My museum is looking into using hyper-tufa in an exhibition about sustainable architecture. The material would be used to make pedestals for models to sit on. One of the major componets of hyper-tufa is peat moss. Does anyone recommend against using this material due to the hygroscopic quality of the peat moss? Thank you!
