What's happening to this Mohogany?????

[Jim Colombo]

My brother sent me, via parcel post, some Mahogony he picked up 16 years ago. He was told it was from the 1940's. It's been sitting in his cellar in New York for the past 16 years. When I got the package, some of the wood had a sticky sap on it. the sap has since crystallized. Does anyone have any idea what's going on with the wood?

"Does anyone have any idea what's going on with the wood?"

Sticky sap has oozed out and cryatallized.

That's what I love about this place. You ask a question...and no matter how technical or difficult. there is someone to provide an in-depth analysis, based on years of research and dedication to satisfy that overwhelming urge to know.

This wood is over 65 years old. I should think all the sap has long gone. Could the low pressure in the cargo hold of an aircraft have something to do with it?

[Jeff Nicol]

It looks like it has had some sort of critter in it that left behind its "SPOOR" and that is the goo. I know all the technical terms I am using my throw some of you, but I really am a doofus woodturner! Wood and basements can cause dry rot and bugs etc. The end piece looks almost like particle board with maybe a thin veneer on it, so maybe not solid wood.

But I am half asleep from chasing my 17 month old grandson all day! Where do they get all that energy??

"sticky sap" can remain in certain woods for decades and centuries. I have cut into yellow pine timbers used in late 1800's New England construction and found pockets of sappy resin numerous times. There may also be some pockets of crystallized sap as well. I don't know mahogany well, though.

[Ed Morgano]

I don't know mahogany either but the "sap" in wood doesn't really leave. When we dry wood, the moisture is removed and the sap hardens to some degree. I would guess that this wood being stored in a damp celler for 15 years might have absorbed enough moisture to soften the sap and now that it is in a dryer climate, the moisture and sap are being drawn to the surface. No expert here.... just a theory.

I have never seen that on Mahogany before, but that is a wood that I don't get much of. I have seen that on Spanish Cedar though. Do a scratch and sniff test. Mahogany doesn't have much of a scent.

This is only found with people in Calif. You might check with Calif. for more information on the subject!

That's some odd looking mahogany; was it painted at some point?

I work a lot with koa. And that looks like the beginning of dry rot. Just my 2cents
