They left behind 7 tons of nails at the fortress of Inchtuthil in Perthshire.

Often nails found from the 19th century are coated with rust after years of sitting in the ground. This can make it difficult to determine their shape or construction. Regardless of how bad they are, we collect them all.

Blacksmiths heated iron ore with carbon to form a dense mass of metal, which was then placed into the shape of square rods and left to cool. After re-heating the rod, the blacksmith would cut off a nail length and hammer all four sides of the softened end to form a sharp point. The hot nail was then inserted into a hole in an anvil and, with four strikes of the hammer, the blacksmith would form the rose head.
This traditional design had the benefit of four sharp edges which cut deep into timber. When the wood fibres were damp they would swell and bind around the nail, ensuring an extremely strong fixing. In the late s, a machine was designed to automate the process of nail production. This machine had three essential stages: first, a triangular strip of metal was cut, giving the desired width of the nail; next, a lever held the metal in place, and then a third lever formed the head.
The metal was then turned through degrees to cut the next equal and opposite nail shape off the strip. These are known as cut nails. Automatically produced wire rails could be made without human intervention and were cheaper to produce.

The ancient Egyptians and Romans used organic glue for wood furniture, especially with decorative veneer techniques, but like much advanced technology, glue for wood became a lost art after the collapse of Rome in until the Renaissance, around , when glue and veneer techniques reappeared.
During the Middle Ages, furniture was held together with pegs, dovetails, mortise and tenon joints and a few nails. Archaeologists have found hand made bronze nails from as far back as BC. The Romans made many of their nails from iron, which was harder, but many ancient iron nails have rusted away since. The hand-forged nail changed little until well into the ‘s.
