Gold was incredibly malleable. It was a fact no one that worked with metal could deny. A single ounce of gold could be stretched and stretched into wire so thin no jewelcrafter had ever been able to walk as far as that particular wire would uncoil out to in a singular line. Master Li often bragged it would reach from Lhavit to the great capital of Syliras if a Master Jewelcrafter stretched it right. Kelski wasn’t so sure. But what she did understand that gold had amazing ductility.
Ductility was a term jewelers and metalsmiths used to measure a metal's ability to withstand tensile stress. And jewelers could put major stress on metals. Gold was capable of being pounded, pulled, stretched, and ultimately hammered until it was thinner than paper. One could pull the two ends of gold a bar of gold away from each other and it would actually stretch like fabric and retain that stretch. It was a miracle material.
She’d watched Master Li work it too many times to not understand that fact. Gold was indeed the most malleable of metals. And her aim today was to make some gold sheets so she could carefully cover the Daggerhand wooden masks in the way – and in the budget – they had for the task. Master Li loved gilding things and Kelski had seen him do it often enough. His favorite saying was that gold in the same mass as a Kina coin could be thinned repeatedly until it was too thin to measure and could be stretched over the area of large area rug in a home’s great room that Lhavit tended to favor in their architecture.
That meant a single ounce of gold could be beaten out into a sheet that is 300 square feet. And when it got that thin and that stretched, it was somewhat transparent. A candle could be held up next to it and in a darkened room one could see the candle perfectly from the other side of the sheet. Yet that gleam…. the gleam still remained. So, for the first time on her own, Kelski was going to attempt to make some sheets.
But it indeed needed special handling… because thinned gold was incredibly delicate. But to stretch a bar and make it that thin, Kelski had to do some specific things to the gold. In fact, she had to add in a little silver and copper to act as a binder to keep the metal flexible and well able to stretch. The ratio was easy. Master Li always said it was ten percent copper and ten percent silver to eighty percent gold. Kelski knew she didn’t need much material to get started on the masks for the Daggerhand, but if she was going to make sheeting, she might as well make it worth her time and do a batch big enough to serve her for a season or more at the same time.
