On the table were various metals, a scale, crucibles for heating and mixing the metals, and a mold.“All that is needed is here,” Keith responded formally. “I will assay the task.”Keith had been honest with Maddie when he told her about creating an alloy with the same specific density as silver. But the task that was before him was far more sensitive than the typecaster’s art. Gutenberg’s secret alloy for lead type contained not only lead, but also tin and antimony. Primitive experiments in pouring hot metal type left gaps in the printing from some letters being smaller than others due to shrinkage while cooling. Unlike most elements, the highly toxic antimony has the property of expanding as it cools from molten to solid, not unlike water turning to ice. Its melting point is over 600°. Most people equated softness with a low melting point for metals, but the fact was that the melting point of lead was nearly 100° higher than that of tin. Like mixing silica with soda to make glass,. "Nothing's wrong," she said. "It's just that you and Maddie ... I mean it looks like she finished off puberty in a week. She's turning into a bikini model. And you ... you were a little tub of lard, no offence, it seems like just a month ago and now you look like a Calvin Klein model, with your ripped abs and cut pecs and really muscular arms..." Her voice trailed away as she seemed to be lost in thought."Maybe it's magic," I said with a smile. I have to admit that I liked the way she was looking at me. I got half a boner headed for a full hard-on ... for my sister. There was just one problem, or at least an immediate problem, I suddenly had to use the facilities very badly. Aunt Martha makes perfect iced tea, and I had finished off about a quart of it at dinner. "Uh, listen, I need to pee, so if you could step outside, I'll be through in a minute." Uh, no I can't ... not for a few minutes anyway."I had to work that out. "Oh, you want good ol' Cody to think we're getting it on in.
