Question 1

Which coaster blank is easiest to engrave?

Accepted Answer

Slate, by a wide margin. The laser removes the dark surface layer and leaves a pale grey mark with real contrast, no masking is needed, and the result is permanent without sealing. Wood and marble both take more tuning, and wood additionally needs a finish if the coaster will meet a wet glass. For slate, the slate coaster designs collection lists maker-tested settings for xTool machines, and 21 personalised slate coaster ideas collects design ideas to start from.

Question 2

Do wooden coasters need sealing?

Accepted Answer

Yes, if they will ever hold a cold drink. Condensation runs down the glass and soaks into bare wood, raising the grain and eventually staining it. A wipe-on polyurethane or hardwax oil applied after engraving handles this. Seal after engraving, never before, or the finish burns and discolours around the cut.

Question 3

What size should a coaster be?

Accepted Answer

Between 90 and 100 millimetres across for a round design, which suits everything from a tumbler to a mug. Square coasters usually run 95 millimetres. Anything smaller stops catching drips from a wide glass, and anything larger starts reading as a trivet rather than a coaster.

Question 4

Why does my engraving look washed out on slate?

Accepted Answer

Usually too much power rather than too little. Slate marks by fracturing the surface, and excess power blows past that into a rough pitted finish with less contrast, not more. Drop the power and raise the speed, then test a small patch on the underside before committing to the face.

Question 5

How do you make a matching coaster set?

Accepted Answer

Engrave a shared element on every piece and vary one detail, such as a different animal or monogram on each. Cut the holder from the same stock so the set reads as one object. Nest the holder parts on a single sheet to keep the grain direction consistent across the finished stand.
