A while ago @Brandon mentioned engraving sandstone, and we wanted to try it out! So I run a few tests to see what how it worked.
Short answer…not at all like I expected, but could have some really cool results with the right design.
These are the two full designs that I did:
The top coaster is one pass of the laser with transfer paper, the bottom one is 2 passes with transfer paper. The engraved area actually gets lighter not darker with multiple passes. Which is pretty neat, because that would actually give me a lighter color and a darker color to play with in the design.
After a few tests, it was apparent that engraving it once without any transfer paper got me a nice clean bright engrave, and engraving it once with transfer paper gave me a good strong dark engrave.
So I cut out the ‘inside’ of the flower and engraved it once, and then slapped some tape over it and engraved the outlines. and this is how it looked! (Look at the pretty flower, and not my ugly tests. )
I can’t wait to build a design just for this effect. Fantastic suggestion you guys!!
