Hi guys,
I’ve got a client who wants to do a photo engrave on myrtlewood. any suggestions on where to start with the settings?

First find out if myrtlewood is ok to laser - some woods are toxic when burned
Then find out where it lies on the Janka scale
Then find the :proofgrade: material that’s closest to it on the Janka scale
Then run tests going up and down from the :proofgrade: setting until you find the one you like :slight_smile:

It works for all materials :slight_smile:

In this case:
Seems to be yes
Red Oak at 1220
(though Birch at 1260 is closer and there are lots of settings on here for that)
and test from there :slight_smile:


Awesome. Thanks!


I’ve been extremely lucky. Is there a list of toxic woods to look for? (or rather lookout for)
Many thanks for the heads up.

Edit: the ones on google aren’t sold at my local hardwood store, probably for this reason.
Dumb luck is better than no luck, but knowledge is priceless,

Lacewood is one that came up in conversation here early - it’s gorgeous but even cutting it, let alone burning, can release irritants for many. Some should be obvious (don’t use poison ivy/oak/sumac leaves in anything), others are more subtle.

This is a crazy complete list - but not everything that is an irritant will irritate you, but generally stay away from the 5 :star: woods!

You’ll note Myrtle is on this list, but way down at 2 :star:s, so with good ventilation…
