Copper bars from Janderhoff and Baslwief get dropped off in one of the large indoor bins of this wide building. Inside, dozens of ear-plugged smiths spend their days at wide anvils beating the copper bars into sheets, rods, plates, and other simple forms used in construction or later further refined by craftsmen into tools and decorations. The hammering din outside the building is nearly deafening, to say nothing of the tremendous thunder of pounding within the structure.
