While waiting for the glass-slices to cool off a bit, Eisen started working on something else so that he could finish the items for the glasses and monocles that he would be making.
He unsummoned glory hole and replaced it with a regular forge that he could work metal with, before throwing a regular Mythril ingot into it. It was easy to make mana flow through to activate the actual enchantment, while being quite light and sturdy, so it was a pretty good choice for something small.
Once it heated up enough, Eisen grabbed it out of there with some tongs and then began to hammer it into the shape of wires with different thicknesses for different parts of the glasses.
