Jacquard Acid Dye for Wool, Silk and Other Protein Fibers, 1/2 Ounce Jar, Concentrated Powder, Emerald 629

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.

This was the first time I ever dyed clothing (stove top method) and it worked fantastically! The color was very deep-- definitely a jet black. The dye was even throughout the garment, too. The colors have not faded at all since I dyed the garments a year ago-- they're still jet black!On that note, do be cautious that the colors will run onto other clothes for the first several washings... similarly, expect that it might tint/stain your skin in high-friction areas (like under arms) until it has been washed several times.I dyed two Smart Wool pullovers from purple to black, and three light-weight wool pullovers with hoods from light grey to black. I probably could have dyed even more...!

Great value for plenty of dye powder that will last a long time. Beautiful color that mixes well with other colors (I purchased 4 primaries for mixing). So far I have dyed about 7 pounds of wool (roving and felt) and have barely made a dent in this container.I highly recommend jacquard acid dyes.

My favorite dye. I love the 8 ounce containers. I find the 6oz ones to be too small.

They do not provide ANY information with the item on how to use their dye or even quantity of dye to use. You must go online and do a search for it. Once you find it be aware there are ONLY instructions are for the washing machine method, NO QUANTITY OF DYE to use doing the stovetop method. Mind you, one MUST use the stovetop method when dying wool or cashmere.After figuring out a method of translating their weight & percentage formula to ounces, and then to teaspoons, I used the dye to very slowly and carefully dye my cashmere. The result was spectacular. It's worth it to go with a true acid dye for protein fiber... which is something I didn't know a thing about prior to researching dying cashmere.

I have a front loading machine so I could not adjust the amount of water. I think with less water, I would have gotten more color and the product would have gotten another star. All things considered, a very good result.

I bought this to overdye some boring navy yarn. With the emerald of this dye, I now have a gorgeous ultra-dark pine green yarn that I am excited to use. I used citric acid granules dissolved in hot water to presoak the yarn, and left the citric acid in when using the dye bath. It took about a half hour of simmering to exhaust the dye (I used the full 0.5 ounce) into the 400g of yarn I had, and it bonded very well with no bleeding in my rinsewater afterwards.

First things first.Protect everything you don't wish to dye. Wear gloves, a mask (which I didn't do, foolishly), old clothes, plastic wrap your counters (maybe your floors as well). Have Clorox wipes on hand if you're working on a stove; use a pot that's stainless/enamel/glass; thermometer (I used a glass candy thermometer that clipped on the side of the pot).When I opened the dye, it looks rust-toned even though the label says Jet Black #626. Do NOT let this fool you. Once the powder hit the water, the resulting color black. Jet Black. Black as the Abyss, Black. Demon Eyes, Black. Seriously Damn Black.The directions I printed out for acid dyeing on the stovetop mentioned leaving the items in the dye bath for 30 minutes (or longer) in order to get a deep, rich color. The items being dyed had been in the bath for a mere 5 minutes when they had taken on a good deal of the dye already - sporting a deep inky black - giving me a clear idea of how well this product worked.I must say, if this initial "test" is any indication of how this product performs, then I've so many wonderful plans for the future.
