Historically, these numbers were associated with the number of times that the wire was pulled through the draw plate.

It was the body of a woman lying on the altar, and in their hands the twins held two tiny, carefully drawn plates.

Wire is commonly formed by drawing the metal through a hole in a die or draw plate.

These thin pieces were then pulled through a draw plate repeatedly until the desired diameter was achieved.

In (c) a thin rod is passed progressively narrower draw plates.

With a mandrel, a draw plate can be used to draw tubes of metal.

Wire is made by pulling a solid metal cylinder through a draw plate with holes of a defined size.

"I recognized the draw plate and that silver solder outfit," Stoddard said.

This can be done on a small scale with a draw plate, or on a large commercial scale using automated machinery.

Draw plates reduce the thickness of wire by reshaping the metal; increasing length while decreasing diameter.

Wire is often reduced to the desired diameter and properties by repeated drawing through progressively smaller dies, or traditionally holes in draw plates.

Frequently, smaller sizes of wire are made by pulling wire through successively smaller holes in the draw plate until the desired size is reached.

A draw plate is type of die consisting of a hardened steel plate with one or more holes through which wire is drawn to make it thinner.

In these publications, he drew plates for William Ogilvie-Grant, George Albert Boulenger, and Michael Rogers Oldfield Thomas, among others.

He was an accomplished and unusual botanical artist, in that he was not only the artist, but also engraver, colourist, and publisher in an era when most artists were only employed to draw plates.

It is believed that they originally were based on the series of drawn wires, No. 1 being the original rod, and succeeding numbers corresponding with each draw, so that No. 10, for example, would have passed ten times through the draw plate.
