Various types of magnolia. I don't know the various names but any wood is worth a shot.
The magnolia I've turned is lovely--- the annular rings are bold but the wood is creamy (like aspen or maple). Polishes nicely. Kinda soft.
The bark smelled, to me, like menthol or eucalyptus leaves. The leaves are broad and VERY thick and waxy-feeling.
Two tips on magnolia
1) If making pens, cut into blanks and begin drying process IMMEDIATELY. If bowls, rough out ASAP and start drying. This wood will turn bluish-grey (ug-buttley!) b/c of the sap content.
2) Dry by soaking either the pen blanks or roughed bowls in denatured alcohol overnight. Wrap with a few layers of newspaper and dry in the house for a couple weeks and then in the open (no paper) for another week or two.
Enjoy. Mangnolia can be some pretty wood if you don't let it blue up on you.
