A couple more random doodle thoughts here and that is about birch plywood.
There are many great woods on which to woodburn – basswood, poplar and birch are common favorites. I just happen to love birth plywood. Birch is a hardwood that can have very distinct grain lines and grain pattern.
Plus you can get birch plywood that includes heartwood stains that are a rich creamy red coloring. As you work birch you will see that the grain lines can become enhanced with the burning.
Birch burning fall into the orange-brown or red-brown coloring range. Because of the hardness of the birch my color range tends towards the extremely pale tones up to a chocolate or chocolate red coloring. It can be most difficult
to get an actual black tone in the burning. Also, because it is a hard surface the layer work tends to develop slowly.
Where basswood might take one or two light layers and poplar two or three with birch I might need four to six layers to bring up the desired tone.
Basswood, though considered a hardwood, is much softer and has almost no grain lines. It is also a very pale or white colored wood. Featureless is often the term used to describe basswood. Basswood burns easily and quickly, your tonal values will develop with a lot fewer layers then you would need on basswood.
In my experience basswood burns tend to the gray-brown tones. You can get dramatic blacks but the pale creamy colors must be worked carefully. Now, I will note here that I do little burning on basswood and it is just a real
quirk of mine … as a wood carver if the basswood is clear and clean enough for burning I have a real hard time not putting it into my carving pile! If it’s not clear or clean as you do sometime get pitchy or spongy basswood I
definitely put it into my carving pile because it’s just not good enough to waste my time burning.
Poplar is a wood right in the middle of basswood and birch for wood color, wood hardness and grain. It is a very white wood with just no grain appearance at all. I consider poplar an ‘unpainted white canvas’. You do have more control with this wood in the palest of tones then basswood and can also reach those beautiful black colors. The tonal values tend toward the yellow-brown color range.
Poplar is often considered a secondary wood for wood furniture. You find it as the drawer sides and backs or as support structure inside your chest of drawers. Since it is not an extremely hard wood or extremely soft wood you
can use your skews and shaders to create actual depth work within a burning.
As you burn along an edge of an element you actual push-drop-lower the physical level of the wood. So with poplar you not only burn but you also add physical dimension to your work. Basswood will also do this.
I believe that Nedra’s favorite wood is poplar and the very features above allows her to work with her portraits and her shader tip to create smooth seamless color gradients. (Maybe she will pipe in here with a few notes about working poplar?!?) In contrast, the hardness and grain lines of birch are the features that make my working with a skew or shader muddy and speckled in appearance.
So what technique or style of burning you chose can determine what wood you want to burn.
So – back to birch - If birch is harder to burn, needs more layer, has definite grain lines and even heartwood stains why would I want to use it. Because the hardness helps me control the coloring, I don’t get accidental darks and I can get extremely pale tones that I could not get in other woods.
Also as a hardwood I can work on 3 ply 1/8” plywood without the board warping because of the heat stress. That makes birch very easy to frame as a finished artwork later no worries about fitting frames to ¼” – ¾” boards.
As for the grain, I love it. I love grain and I love it showing through the wood burning. Personally even in the most complex drawings I don’t want to hide or diminish the simply fact that this is a WOOD burning. Personally if I
want a white or featureless burning canvas I am going to grab a piece of 140 lb 100% rag content water color paper ….
But that’s just my preference, hopefully someone else or maybe many someone elses will chip in here about their favorite wood surface.
OK … enough random doodlings of the mind. Nope! One more ... the goldfish and owl were burned using a variable temperature setting burner and the NY Fireman was done with a one setting (Walnut Hollow) tool.
As it has just hit 4AM here I'm off to bed. See ya in the mornin'.

Oh ... if you don' mind I will do my spell checking and editing in the morning. If you do mind I will still be doing my spell checking and editing in the morning.
