Using alcohol based stains and dyes is preferential to water based. After all, you want the lowest moisture content possible when you stabilize.
Place the dye mix in a container and add the wood scales/blocks. Let soak for days or longer. Test cut a piece and see how the penetration is. Pressure and/or vacuum can help in some cases.
sorry guys i need help. i have tried to dye some burl and it will not get past the surface. i can however completely penetrate some maple. both are done with alcohol and powered dye that is supposed to be used for plastic and clothing. i also tested a pine wood block and it is very easy. i have saw where some say wait a long time but then again i see where some companies say push and pull several times. adding pressure and then pulling a vacuum.
i have let the burl wood sit for minutes and then for hours. its all the same. i have not let it sit for days.
would acetone work better than alcohol?
i am using the push pull method of pulling a vacuum and then waiting and adding pressure to the tank with a air compressor. first i use the powder and the alcohol to dye the wood and then wait for it to dry and hope to use 90C to stabilize it.
also this off brand of 90C says to heat it in water for 10 minutes and not an oven. that is all different from what i see others post regarding this process.
1. my vacuum pump will pull a good vacuum or the gauge shows it does. its not a walmart type its a real industrial grade and famous name.
2. my tank i made from high pressure water pipe and flanges 1/2" thick to 5/8" thick with 8 22mm bolts to hole the home made lid on. the tank is 8" in diameter and sealed with a rubber gasket. i have checked all hoses and fittings with soap and water to watch for bubbles. that took a long time to get it 99.5% sealed.
3. i have a industrial vacuum gauge that says i am pulling about 25 to 27 on a 30 dial.
so its not a mickey mouse setup. i think i need a bit of over kill to allow for my errors.
any advise will be most welcome. i am only stabilizing for my self no intent to resale the wood.
