This outstanding powrded leathercraft dye promises to cut costs associated with transportation and storage of bottled leather dyes. Therefore, it will be an excellent option for your leathercraft project.Up to 500ml of alcohol based oil dye in a convenient powdered form, ensuring low cost and easy transportation. Simply mix with alcohol to achieve a high quality oil dye for your untreated vegetable tanned leather.You do not have to incur any extra costs in getting your favourable leather dye delivered to you. This dye works faster, penetrates your leather much deeper and dries much faster than other water-based dyes when used with colourless denatured alcohol (also called Methylated Spirits, Wood Spirit, or Denatured Rectified Spirit).Start by casing your untreated vegetable-tanned leather using water. Take a container and mix one tub of this powdered leather clay with 500ml of colourless denatured alcohol and stir it thoroughly to prevent the crytsals from clumping (use less colourless denatured alcohol to get less vibrant colours). Let the mixture sit still for an hour before applying it on your vegetable-tanned leather using a soft-bristled brush using even strokes.Always ensure that your untreated vegetable-tanned leather is cased with water if you want to achieve consistent results. After you are done, seal the remaining dye in an alcohol proof vessel.While you can have some dye crystals that did not dissolve in the colourless denatured alcohol that settles on the bottom of the container, ensure that the leather does not contact them as it causes streaking on the leather.Please note: The powdered dye is meant to be mixed with colourless denatured alcohol exclusively (rubbing alcohol, or other kinds of alcohol are not suitable for this product) and the mixture used for treating vegetable-tanned leather alone. This dye should only be used on vegetable-tanned leather that has not been previously treated or dyed. Unfit for use on treated leather like those of handbags manufactured in factories, tabletops, jackets, leather seats, car seats among others. The reason is that a good number of these things have been pre-dyed or pre-treated to discourage subsequent dyeing. There's a great possibility of them having a plastic layer that inhibits the uptake of the dye. However, it is possible to test whether the items can be dyed. Take what you refer as pre-treated or dyed leather and completely clean it using a recommended cleaning agent. Proceed by putting a drop of alcohol on the treated portion. You may need to rub in the alcohol gently. The results can go two ways: the leather absorbs the alcohol without ruining the leather, or it ruins it. The first result indicates that the dye is suitable for leather. Since impeccable results are not guaranteed on pre-treated or pre-dyed leather, it is prudent that you contact the manufacturer for information. A rule of thumb for us is that you always test the dye on a tiny portion of the item before deciding to dye the whole item, especially in the face of uncertainty of the suitability of the dye to the leather.
