Review: Excellent product - Excellent price and quality dye which I used to dye knitting yarns. The colors are beautiful. I have used this brand for years and it is always perfect.
Review: Worked beautifully! - Review for Jacquard Acid Dye 1/2oz Jar Navy Blue - Acid Dye. Worked beautifully! I used 4 liters of water, 200 ml of vinegar, and 2 tablespoons of dry color powder for a weight of 350 g (dry fabric of a dust white 100% linen dress). Using gloves, I wetted the dress in warm water and immersed it in the pan, brought the water to 180F, added the vinegar and stirred for 30 minutes. Put a stone on top of the fabric to keep it submerged. Let it cool. Rinsed the dress with cold water till the color stopped bleeding out. See the pictures for details. I turned a bit lighter than expected, but I am pleased with the color. It dyed evenly, and it also stained the buttons, changing them from brown to a dark blue as a bonus. It did not smell. I hand-washed the dress once in cold water, and it did not bleed. I am very pleased. Kept the blue solution to dye a white natural wool, and I will see if it will still work, as stated.

## Features

- Vibrant Color Payoff - This Jacquard dye creates intense and beautiful colors including a wide array of fluorescent colors. Experiment with different shades by using less dye and more water to create pastels, and more dye and less water for deeper, bolder colors
- Best on Protein Fibers - Use as a nylon dye, wool or alpaca yarn dye, or to dye silk, feathers and animal fur. This dye can also be used on anything Nylon, so it can be used to color nylon wigs, tights, leggings and swimsuits, perfect for cosplay
- Self-Leveling - Creates level, uniform colors when submerged in the dye bath. Try immersion dyeing, tub dyeing, direct application, garment dyeing, yarn dyeing, and itajime or shibori. Create a concentrated solution for silk painting or add thickener for screen printing. Steam setting is needed for these methods
- Permanently Bonds to Fabric - Once the acid is added to the dye solution, the dye "magnetizes" to the material and bonds with the fibers. This also means the dye is pulled out of the water, leaving you with clean water to dispose of after the dyeing process, making clean up a breeze
- Easy to Use - Heat the water to 180 degrees F (80 degrees C) then add the dye. Add wet fabric to the dye mixture, then add chosen acid (vinegar or citric acid). Acid Dyes are stable in solution, allowing you to save the dye bath or stock solution for future use

I never write reviews but the color was accurate and now instead of a dowdy grey cashmere sweater I have a vibrant green sweater. Easy and simple process.
