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.
Applied the Tung Oil lightly and let it sit for 15 minutes.
Engraved at 900 speed, 30 power, Vary Power, 270 LPI.
I’ll let it sit and cure now without messing with the image.
