I have a few old pour silver bars that have an unusual pattern of ripples and ridges. Does this pattern have a name or terminology? Thanks.

cooling lines or cooling marks...
So, they form as the silver cools. Thanks. I read somewhere that they are most prominent when the mold is cold so this makes sense.
