Abstract
An experiment was made using a tin can 9 cm wide, 21.5cm long and 10 cm deep into which shells, pieces of earthenware, pieces of animal bones, etc. were put, making it a suppositional layer of a shell mound. Methyl methacrylate monomer was used with benzoyl peroxide as accelerator. The liquid resin was applied several times and then a plate of the same resin 10 mm thick was placed in front of the layer and the syrupy resin was poured between the plate and the layer. It was necessary to keep the temperature of the test piece at 30°C during this process so that no air pockets could form and the resin could harden. -- AATA
