Abstract:
Production of jewelleries of brass scraps from Samples collected from various places in Gombe metropolis through random sampling techniques was perform and presented in this study. The study uses local techniques for jewellery production using the available brass scraps collected. The samples collected from various site were casted in to various forms, shapes and design and compared with established practical values (visual quality) entailed for jewellery production. It was discovered that brass scraps collected are of different type's base on the nature of its colour, weight, surface and mechanical structure (i.e. malleability and ductility). Samples 1 (tap heads) and 2 (car part) are not malleable and ductile as samples 3 (ornament) 4 (trumpet), 5 (car pipes) and 6 (dishes). The study concluded that sample 1 and 2 can be water cast to produce abstract shapes or to be modified by adding other elements to improves their mechanical properties, whereas using samples 3, 4, 5, and 6 produces high quality surface finishing jewelleries which was easily produced by cold working. Finally, this study will help local jewellery producers in selecting quality scrap brasses that will be suitable for jewellery production.
