So in keeping up with my current slate project, decided to play around with surface prep. There have been discussions of Mineral Oil and Shellac. So I was working on some slate signs for our seasonal parts at the farm where we keep our horse and have the goats. It’s a fairly fancy party so the owner was interested in our slate. So first I did it with mineral oil thinking that might be better than the raw slate, and that started off nice, but actually faded overnight?? so i tried shellac (spray shellac to be precise), the raw slate is from my first slate project:
I ordered some of those after your last post. They’ve of course gone on the huge pile of materials I have no current use for, but you never know when you’ll suddenly need name plates for a horse party.
And bonus - real shellac is just bug poop and booze, so it’s laser compatible! (“Shellac” is sometimes used as a generic term for varnishes, though, which may not be; check your ingredients).
Any thoughts on whether the engraved slate is weather-resistant? Or will the markings fade with the first rainstorm? I was thinking of making some miniature headstones for our pet graveyard and thought some engraved slate might look nice.
