Zoology laboratories from public and private institutions, schools with a Biological Sciences room, Chemistry Laboratories, all references of anatomical pieces for use in their practical classes. The use skeletons assist in scientific and didactic activities, because it provides safety information about specific adaptations vertebrates, such as, support, posture and mode of locomotion. Such pieces require time and high cost to have a satisfactory result for your exhibitions. The main objective this work is the elaboration and organization information about an alternative technique of low cost maceration bone pieces for didactic collections, making comparative analyzes on the cost / benefit relations this technique. Two products were used: papaya pulp and pineapple pulp and evaluated as experimental conditions such as: concentration and exposure time. the maceration process used for this work had a good effect on the pieces and associated with the boiling process and bleaching using hydrogen peroxide we managed to reach our goals insuggesting an alternative maceration technique in the preparation of bone pieces without them losing their firmness , its anatomical shape and the quality for display without wear bon.
