Any tricks to drying Magnolia?
« on: June 27, 2018, 03:14:38 PM »
We have some 10/4 X 20"+ X 9' slabs as our first time drying Magnolia. Wondering if air drying for a little while will they stay white or should we go right to the kiln.

In this heat, if you do not run fans on the air drying stack, the magnolia will stain.  I would run a couple of 36" fans on the stack for about 6 - 8 weeks to let them air dry before kiln drying. Since I almost always pre-air dry before kiln drying, I do not have any experience with green magnolia going directly into the kiln.

According to what I found at the USDA website it dries very easily using a pine schedule if it is the Magnolia grandiflora and Magnolia virginiana species. It did not report any defects to watch for specific to it. Gene may have more on that.

I've never dried magnolia but I believe magnolia and yellow (tulip) poplar are in the same family, so I would assume they have the same drying characteristics.  Very prone to sticker stain, but high allowable moisture removable rate, pretty forgiving otherwise, etc.  Easy to dry, hard to keep from zebra striping.  So I would treat it like poplar.

If green going directly in the kiln, I would 1/3 short load the kiln so that it's moisture removal capacity isn't overwhelmed, and maintain a 10 depression, airflow up around 500 FPM.  Watch the moisture removal rate to stay high up on the curve but not enough to check the thicker stock.  Inspect it and the kiln routinely until I knew things were OK and felt right, just because I've no experience with magnolia, but have done a lot of poplar.

If air drying, do as WDH suggests, put the big fans to it ASAP, or faster. ;D

A few weeks air drying and it will be significantly drier and less prone to sticker stain in the kiln.
