| - | I left two of these coasters on the sample shelf to the left of the entrance door if anybody wants to see them in person. | + | Found these slate coasters locally...they were $7.99 for a stack of four with non-skid "feet" on the underside. Slate can engrave very inconsistently, depending on the source of the slate. This slate wasn't marked for its country of origin, so I risked the $8 and gave it a try...got lucky and they worked pretty well. |

| These take about 15 minutes to engrave a single coaster using the suggested max power settings marked on top of our laser (so we don't kill it prematurely). The time required per coaster should be much lower if several are placed side by side and all engraved together. A simple jig would simplify lining up multiple blanks...just mark (or cut out) a 4 inch square for each blank, center a copy of the artwork in each "location". Make the squares one color (and set those to "Cut"...if you only want them marked, still use "Cut" but lower the power so it only marks the outline of the square). | These take about 15 minutes to engrave a single coaster using the suggested max power settings marked on top of our laser (so we don't kill it prematurely).

| - | The powder wipes off easily with a soft cloth, a wet cloth if you prefer, or wipe it on your jeans. | + | The powder wipes off easily with a soft cloth, a wet cloth if you prefer, or wipe it on your jeans. Slate may have some inclusions that don't react consistently to the laser. If you enlarge the first photo, you can see a few of these adding "character" to the coaster. If you're buying a batch of blank coasters to run a for-hire job, it's worth considering adding some extras so you can reject any that have too much character... |
