They did not have the benefit of cheap, off the shelf, mass produced batteries. Bronze is a relatively hard alloy of copper and tin, better suited for the purpose than the much softer copper enabling improved durability of the weapons and the ability to hold a cutting edge.For many years the telegraph, and later the telephone, industries were the only consumers of batteries in modest volumes and it wasn't until the twentieth century that new applications created the demand that made the battery a commodity item. The use of bronze for tools and weapons gradually spread to the rest of the World until it was eventually superceded by the much harder iron.Bulk diffusion experiments are performed using a custom diffusion cell that employs a fiber optic infrared laser (with contact thermocouple feedback) as a heat source.Laser microprobe helium measurements and depth profiling involve the use of a New Wave Research Ar F excimer coupled to the feature four collectors (one Faraday and three ion counting multiplier detectors) and are ideally suited for high-precision work on small sample aliquots.
