Francis I

Interesting subject, I also had an idea for a book where the gold would be casted (mixed with iron) instead of iron into piano harps (plates). Actually I started believing that it is possible and thought that it is actually a good way to hide gold in plain sight. But it appears to be not so easy to achieve from what I read here or maybe it is not considering how much gold could be used. Maybe it would not even be mixed with iron, but not sure if the gold may be too soft to hold string tension. I did see couple of piano plates that looked like they bended Since I most likely won't write that book, I'm sharing the idea so someone who can write well can use it I would however like to know if such thing is possible. Pressure created by strings is over 15 tons but there are support studs under the plate and soundboard.
