Red deer skins were treated in a variety of ways, divided into ten sampling squares and identical regions used to compare the tensile properties. Samples were also aged for 6, 12 and 18 months in an accelerated ageing oven. Differences in the stiffness and elasticity of the material were monitored by comparing tensile strength, percentage elongation at tear and Youong's modulus. Upon ageing the majority of tissues deteriorated at similar rates irrespective of treatment.
