Happy to indulge the curiosity of others, I make sure she has a decent view of the process without being endangered by the heat or any flying sparks. The language barrier makes it difficult to explain things, but there are several things I can show without words. My drawings of the breastplate I am working on, how a steady stream of air from the bellows takes the burning mixture of coal and coke from simply hot to enough to melt metal. The way a difference in temperature takes even the stiffest metals to the point that it can be molded with relative ease.
If she shows an interest in getting a little hands on, I'll provide an apron and gloves. There isn't much she'd be able to handle, but I could have her pumping the bellows or helping hold a piece in place as it is worked.
I've already been working on Thomas' breastplate for a few days, so the general shape is done. Tonight's work involves shaping it to the torso measurements I got from my companion a while ago. Its a meticulous process, heating a small section of metal, then hammering it over the anvil horn for a while, constantly double checking dimensions throughout, and repeating this over and over again as the metal takes form as more than just an oddly cut sheet of mithral.
