Gift for a departing colleague on slate prepped with oil & beeswax…

Why do I feel like that scientist. I’d have used a lightening rod and something to push the button.
XKCD is my hands down favorite web-comic. You should do another and send it to Randall.
You used both oil & beeswax before lasering?
Very nice! what are the dimensions?
Yes – Howard’s Feed-n-Wax, applied about 30 min before zapping. Really increases the contrast. In a pinch, I just use mineral oil.
Edited: Full props to @kittski for sharing her technique.
Approximately 5x7 inches, (~15.5 x 17.75 cm). I buy these for about $2 each at Michaels.
I’m just tickled to see the difference that PRE-oiling makes in the contrast. When I did mine months ago, I oiled after, and everything disappeared. Whoops!
So I had to burn another batch.
Interesting. I had just applied some mineral oil to slate this morning that I was going to try. I will have to pick up some of the Howard’s stuff as well.
I wouldn’t have to push it…I have some stupid friends! Ha! (Observe and wait, observe and wait…)
