Very simply put, stains are very thin paints and dyes are why your socks are red out of the washer. You can let the inlay stock soak in a dye solution overnight for better penetration and I bet you can even use one of those kitch sealers to help drive the dye deeper into the wood. These synthetic dyes delivered the same sparkling colors as the natural ones and were lightfast to boot. If you plan on submerging the wood or any possible prolonged water exposure- like a boat- I would suggest a chemical sealant to prevent water damage to the wood as well as leaching of the stain from the wood. There are many different types of dye and coloring products available for wood.
Because the dyes are concentrated they can be diluted up to 10 times their volume in water and still have extremely strong dying capabilities. The best way to get a warm black is to chemically stain the wood ebony with iron acetate (soak steel wool in vinegar overnight and you will have iron acetate). At present, most gel stains are oil based pigment stains, so they behave rather like the liquid versions of oil based pigment stains. Setting agents used with dyes are in such a high concentration that can be harmful if not handled and disposed of properly. It was only when I came to live in England and became interested in natural dyes that I learnt more about this tree.
I never really bleached wood before so don’t have any experience there but it is certainly possible that some residual bleach was on the surface. Not withstanding the fact that these dyes occur naturally they are also a means to achieving authentic colour reproductions. A third method for coloring wood is by a chemical reaction of various solutions with the wood itself. A small point, no so much about safety but about cleanliness: remember, these dyes are DYES!! Many species of wood change color, quickly or slowly, when exposed to direct sunlight. Though it’s not really bleeding under but being carried under by the wood itself.
The manufacturer of Procion dye (which is not Dharma) says that the dyes and rinse water is not harmful to septic systems. If you like this project, please check out more than 1,000 shop-proven paper and downloadable woodworking project plans in the WOOD Store. Natural earth pigments are used for colouring a wide variety of materials including French polishes, glues, varnishes, wood fillers, oil etc.
Wood scrap was pine sanded to 180, about 80 deg F in my garage shop and 70-80% RH. The Transtint, even cut in water not alcohol, was showing signs of biting in and drying up almost immediately upon hitting the surface. Brazilwood, logwood and fustic are famous traditional natural dyes that produce bright colours on wool, cotton and silk; brazilwood yields rich reds, logwood purples and fustic strong yellows. It is used extensively as a mordant for the natural dyes and to give better penetration to water soluble aniline dyes. The goal is to remove as many of the shiny spots as you can without sanding back into the wood.
Keep notes and make a test on a scrap of the same wood as to be dyed, evaluate colour after wood is dry. All 19 dye colors (10 wood tones & 9 accent colors) are intermixable to produce custom shades. As hinted at above, wiping on water based dyes may not be the best application method. Stains should be stirred often to insure an even dispersion of pigment because the particles tend to settle on the bottom…..don’t you just hate gravity?! The dyes used in woodworking are actually very similar to those used for dying cloth and other materials. Unlike stains that concentrate in the areas of the wood that have large pores (like end grain), dyes penetrate all parts equally.
When dying both types of mahogany some success with obtaining a true color can be had if the wood is bleached first. Alcohol spirit based wood stains for use with lacquers, or alone as penetrating wood dyes. Alder is a little less porous than maple and depending on the particular piece of wood may require differing degrees of preparation. I have been trying to find non-toxic stain for my bunny’s toys for ages, and had just never thought of this.
A good trick some use is to tape off the wood edge of the binding leaving only the binding exposed and shoot a layer of clear coat over the binding before applying any dye. Always use caution and observe the finish on your wood piece regularly to ensure it is not being scrubbed away along with the dye. Dye stains also tend to penetrate more deeply, leaving more color on the wood surface after theyve dried. The ability to lighten the dye (that is, remove a significant amount of the color) after you have applied it to the wood.
These dyes will not tolerate non-polar solvents such as hydrocarbons at any proportion. Water based dyes can only be applied to unfinished and unsealed wood whereas alcohol based dyes can be either wiped onto unfinished wood or sprayed over filled and sealed wood. Manns Water Based Wood Dye colours can be thinned for a lighter more translucent shade by simply adding water and stirring thoroughly.
Apply the Palette Wood Dye fairly quickly along the grain using a foam applicator or brush. Gibson and PRS use alcohol reduced dyes to tint their translucent finishes and fading doesn’t seem to be much of a problem to these manufactures. The aniline dyes distributed by Craft Supplies are made by Libron and they are of good quality for about $3.00 per ounce. It is used in furniture finishes and most stains and varnished but is not safe for kids. Apply the dirty water to wood and just like stain, it will leave color on the surface.
While not raising the grain, alcohol and solvent soluble dyes dry too fast to apply a primary color over large areas without having visible overlaps. The basic characteristics of our liquid dyes are good light fastness, good resistance to overcoating, very good compatibility with a wide range of solvents, good storage stability, low viscosity, fast drying, non-flamamable and ease of use. I know you are giving examples of what to cover the wood with in order to not have the colors bleed, but please don’t recommend linseed oil. Dyes will color very fine grained wood, like cherry or maple, which pigments will not.
I wonder if food coloring has any special ingredients to make it washable?” I’ve been happy with liquid watercolors, sealed, for average play by non-mouthers, but over the years I’ve eventually become convinced that there is just NO way to dye wood to keep it from bleeding when a kid puts it in her mouth. A water-based wood dye will provide fade resistance, raising the grain of the wood to create astonishing effects when used in conjunction with an appropriate transparent finish. Potassium permanganate can also be applied to wood species that are low in tannins.
I’m using the colours and shellac for artwork…so don’t have any other considerations concerning the grain of wood and absorbency to consider. If you see dark zones around the nail or hinge, then the wood species does react with iron to create color. Dip a piece of scrap wood (or use an area of the wood you’re using that can’t be seen) into the bowl of dye. Sanding beyond 150 or 180 grit prevents these types of stains from working well.
It can also be used on woods that are low in tannin by prestaining the wood with a tannic acid solution. These three dyes are made from the heartwood of medium to large trees originally found in tropical forests. The odd thing about fuming is that the color change is not very evident on dry, unfinished wood. Leaving wood outside uncovered for long periods also causes ultraviolet erosion of the wood. Wet the surface of the wood with a damp paper towel while it is spinning on the lathe.
Before you go to dip your rag or paintbrush in the coffee, you may want to put on rubber or plastic gloves to keep coffee stains off your hands. Spread the concentrated color on paper or scrap wood until the color becomes even and about the intensity you want. To obtain strong colours, put 50 grams of wood chips in a saucepan, cover with boiling water and then leave them overnight. Here’s how I dye floors; the photos are from my panel at the NWFA’s Expert Sand & Finish School last October. Changing or enhancing the color of wood while letting its grain show through has been a favorite finishing technique for centuries.
These stains sit mostly on top of the wood so they don’t add much color unless you leave them thick – in which case they muddy the wood. TransTint dyes concentrated formulation allows the user great latitude in using the dye because glycol ethers are compatible with a wide variety of finishing products. It is used by violin makers to stiffen the wood they use to make violins to make them sound better. TransTint dyes are a single component concentrated metallized acid dyestuff dissolved in a glycol ether carrier.
To prevent cross-contamination or dilution of the original color, never return used concentrate or thinned wood dyes to the original container. Pre stained fillers are available from Bartly’s and can be found at fine woodworking stores. He has written numerous articles for international woodturning magazines, which have been published in more than 78 countries around the world. Stain Dyes are made of much smaller particles, which are dissolved in a solvent. If you want vibrant tropical colours that conjure the spirit of Brazil and the Caribbean, then tropical wood dyes are the ones to use.
