Slate / Stone Engraves fading

[sailbyc]

I used Tung Oil on slate and let it cure for a few days. Same effect, but no issue with Oil seeping into the design.

Slate Etch with Tung Oil

I wanted to make a slate coaster as a Valentine’s gift for my daughter, but I don’t have any mineral oil. Sooo…I do have Tung Oil (100% pure, avoid those thinned with flammable stuff) and so I gave it a try. The result looks great to me and the Tung Oil should cure and harden. Hmmm. Apply the Tung Oil lightly and let it sit at least overnight. Engraved at 900 speed, 30 power, Vary Power, 270 LPI. I’ll let it sit and cure now without messing with the image.
