Hi LJ’s
I need to dye some wood that is 1/4inch thick and need to get a 100% penetration, that is complete change of colour.
Can anyone recommend a type of wood that is suitable to achieve this, please????
One I have thought about is Birch, but that is not available her in Australia, so I need to know what will work before I get any overseas material.

Hope you can help me.

Bob.

Why do you need to dye the piece 100% through? I think that might be difficult to achieve, but I’ve never tried. Seems like if you used an alcohol-soluble dye, it would dry too fast, and if you used a water-soluble dye, the dye would get to a point where it would have trouble absorbing past a certain point.

I’m curious to know what you’re using this for.

I would try Aspen and use a alcohol based dye. I have had good luck dying it red but never measured the penetration.

Hi Bob. You might need a vacuum to pull the dye through the fibers 1/4” thick..or maybe submerge it or put the wood in boiling dye. I don’t do any dye work…just brainstorming!!
As for the wood,,, i think palm wood might work.

cheers, Jim

Pressure treat it.

Not easy to do on a small shop level.

I can tell you I’ve tried to dye thin (like 1/8” thick) veneers with black alcohol based dye by soaking them in the dye in a 1 gallon ziplock bag. Not much of the dye got in very deep. Turned the insides kind of muddy grey. I think that it will be necessary to submerge the pieces in the dye and then pull a good vacuum with a vacuum pump and chamber. Then, when you release the vacuum the solution will be drawn into the wood. This is what they use when they resin impregnate wood to stabilize it.

If you need a solid color, couldn’t you just paint it?

Birch would not be a good choice as it is very dense with tight pores. I’m not sure that what you want to do is even possible. The only way to get any penetration at all will be in a vacuum chamber, a softer wood like poplar is what I would try first. How big a piece are we talking here? A small vacuum chamber is easy to build a bigger one will get expensive.

Can’t help with wood type Bob but I have fond mixing wood dyes with metho get fairly good saturation when brushed on pine and plywood. Maybe if you soaked it for a period of time it would penetrate soft woods. Best of luck mate, what is the project?

Probably a burl of some sort. All that end grain helps absorb the dye. I’ve had success dying veneer by simply soaking it in alcohol dye for 2 days but I don’t know how well that works on thicker wood.

Thank you for the feed back, it’s greatly appreciated.
I am trying to get a good range of coloured wood to use for “Segmenting”, which means the colour has to go deep into the wood.
I have no problem with changing the colour after it is shaped and sanded, but that doesn’t work when you have to assemble the coloured pieces and then turn to shape.
Size of the pieces is not really a problem, but they would need to be 1 inch (25mm) or more wide so would fit into a vacuum chamber, if I had one. I do have a pressure pot though.
Thanks again for your input.

Bob

Just be very careful to do research before putting flammable materials under pressure. I don’t know what the safe limitations are. However, I do know that people have blown up pressurized air tanks when they put oil inside them. Something to do with lowering the flash point and the heat caused by the pressurizing process.

I was curious about how to make something similar to spectraply so did a search and found a couple of links that might be of interest:

Since you did not specify the application I would suggest balsa.

Lazyman, Thank you for that info. Some good information in those links.
It looks like I will have to build a Vacuum chamber.

Thanks to you all for your help.

If you do try this, let us know how it works (might make a good blog entry). I have toyed with the idea of trying to make my own spectraply.
