Set in metal

I'm working on a project. Part of it is pictured above. It involves writing in silver sharpie on a black background. And as I work in it, I can't help but think of the inscription Sazed finds in chapter 12 of The Well of Ascension at the Conventical of Seran:

I write these words in steel, for anything not set in metal cannot be trusted.

Of course, I'm not etching anything into a plate of steel, and it's certainly not as important as what went down in that book, but it definitely has me thinking.
