Jacquard Soda Ash Powder - Sodium Carbonate Washing Soda for Laundry & Dye Setting - Tie Dye Soda Ash - 5 lb Bag Soda Ash Dye Fixer - Super Washing Soda for Laundry & Fabric Dyeing

Super easy to use and seems to work great! Huge difference between no soak and soaking for 20-30 minutes. Definitely worth getting!

Good price compared to other brands. Use for tye dye so works great.

It magically set the colors on denim. A must have.

Really makes a big difference in tie dying if you soak your item in the soda ash, my shirts came out very bright!

Good for delivery and packaging.

Always legit

Exactly as described. I’m thinking it should last a long time. Glad I bought this particular appliance.

If you're doing tie dye, put the soda ash and your undyed cloth or clothing into a bucket of water together BEFORE you dye your fabric,. This prevents the colors from running like they would if you did a soda ash bath after your cloth was already tie dyed. This product works insanely well. You just need to use it right! (If you're not doing tie dye, but instead you're just doing a dye bath where you fill a bucket with water and dye, you can add soda ash later and it's no problem) More review and tips on how to use soda ash below I've been using this soda ash for about a year now. It works REALLY well, pretty much any color you dye stays put after you rinse out the dye. Can be added to dye bath immediately or later depending on preference. Both methods lock in the color. I haven't tried this with natural dye, but I know that with MX dyes or RIT dye this works perfectly. You don't need a ton of it. maybe a quarter to half cup per medium sized (about a foot tall x foot wide bucket). so if you're not dying a ridiculous amount of yardage this bag should last a decent while.

Este producto lo he utilizado como mordente para realizar un tinte en una tela y me ha sido muy útil.

Used in a recipe to develop 35mm film in beer and it works, 500 ML of beer, 50 gr of soda powder and 15 gr of pure vitamin C

This soda ash is perfect for cleaning the turbulators on oil boilers, which is what i purchased it for. A1 item.

Delivers as needed

Used for cold water (a misnomer, actually lukewarm water) bathing - dyeing method. Was recommended for this process and glad I ordered it. Just wish I could have found some clear directions for how to dilute (re concentrations) for use. Approximated and got lucky I guess. (Although maybe I got away with using less than ideal bcos I also added salt). Glad too, that I read someone recommended using mask and goggles. Definitely needed imo. And still need to wash face after each stirring/agitating of the batch (I also ended up having to keep the pot outside - lucky it had a lid - cos of the fumes). If you have asthma or any other breathing issue I would definitely recommend you NOT use this product
