![]() This causes a chemical transformation in the tannins that makes them black, but leaves all the character of the wood because the color is in the wood instead of on top of it. The test is positive in 50 of patients, but false-positive results can occur culture of a CSF sample is required to confirm the diagnosis. The better way to ebonize a wood, especially if you want an even tone, would be to sand the oil off, apply a quebracho bark powder tea to the surface to increase and regularize the tannin levels across the floor, and then apply iron acetate (vinegar that has eaten some steel wool) or iron sulfate (available in nurseries to correct leaf yellow iron deficiency). The India ink stain or the fluorescent stain (the commercially available Calco-Fluor white stain) is important in screening CSF samples of patients with suspected cryptococcal meningitis. Due to differences in the wood it is very hard to get just the right amount of this on there so that the grain shows through, and the floor doesn't appear splotchy. It is applying an opaque black film on the wood, covering the wood. Basically the stain is just thinned paint anyway. You could darken the stain with black oil paint. The only thing you can do now to even out the "color" is to apply oil based substances or sand it and start over with water based. You worst case is that the oil based stain has not completely saturated the wood's ability to absorb, and some India in does soak in leaving the surface even more splotchy than before, and with a film on the surface that will peel off immediately. So if you put that over a coat of oil based stain, you best case scenario would be a died film that peels.right off the top, leaving you right where you were. Is water plus soot (carbon) plus a water based hardened or adhesive.
