Sand CastingAbraham Darby scientifically studied brass production and was able to make advances in that industry that turned Great Britain into an important brass goods exporter. Darby founded the world's first metallurgy laboratory at his Baptist Mills Brass Works factory, where he refined brass making. He developed the process of sand molding that allowed iron and brass goods to be mass produced at a lower cost per unit. Before Abraham Darby, brass and iron goods had to be individually cast. His process made the production of cast iron and brass goods a continuous process. Darby received a patent for his sand casting in 1708.
Greater DetailDarby combined the existing technologies of casting iron with casting brass that produced goods of a greater intricacy, thinness, smoothness, and detail. This proved important to the steam engine industry that came later, Darby's casting methods made the production of the iron and brass steam engines possible.
