I thought for sure most folks were just using a permanent Sharpie to mark their slabs before cutting preforms, so I did the same. However, as soon as the water hit it on my trim saw it washed it off almost as soon as I began to cut.
Is there some specialized marking tool that you folks use to mark a slab, that will stay on the slab until I either grind it off or remove with alcohol?
Thanks!

markb I use aluminum rod sharpened on one end. It’s pretty easy to see and it doesn’t come off easily.

I like Brent's way of doing it...and I would really like it if I switched over to doing it that way! LOL
I too use a Sharpie...but I've noticed it DOES wash off of certain materials and not others. Those times, I score the pattern with a Tungsten Carbide scoring pen...then use the Sharpie over the scratched shape. That way it doesn't wash off the surface. Not saying this is the best way...but it seems to work for me. LOL

I mark the face with a fine point sharpie, trim and then redraw the shape on the back with an extra fine sharpie. I've never had the lines come off with the trim saw. The only thing I mark with pencil is the girdle line. After removing the cab from the dop, I use acetone, qtips and an xacto with a chisel blade. Most of the time the sharpie lines come off. When they don't I use a 280 soft wheel. Pencil washes off on the trim saw and can when grinding. I am not skilled enough to shape when the lines on the bottom disappear.
