A method for preparing lightweight clay-based aggregates, the aggregates being suitable for use notably in civil engineering works, in particular road uses, and construction. The method for preparing lightweight aggregates includes at least the following steps: a) a step of granulating a clay-based mixture, so as to obtain aggregates, b) a step of drying the aggregates obtained, so as to obtain dried aggregates, c) a step of heat treatment of the dried aggregates, this step having two successive substeps: i) a first substep of heat treatment carried out under a reducing atmosphere at a temperature Ti of between 900 C. and 1200 C. approximately, ii) a second substep of heat treatment carried out under an oxidizing atmosphere at a temperature T2 of between 1050 C. and 1300 C. approximately, and d) a step of cooling the aggregates.

A method to solidify cremation remains includes milling the cremation remains to a reduced particle size, adding water to the cremation remains to produce a mixture; shaping the mixture into wet ware having a desired shape, drying the wet ware to greenware that is sufficiently dry for firing, and firing the greenware in a kiln until solidified to one or more cremains solids consisting of the cremation remains. A product formed of solidified cremation remains is also disclosed.
