Can this be used after tie dying to help retain the colors? If not, what is suggested? Thank you.

Hello Melody and Thanks for the Question. Your garments should be soaked in a soda ash solution prior to tie dye for a minimum of 20 minutes. I like to mix appx. 1-1/2 cups per 2 gallons of warm water. The soda ash helps expand the Cotton Fiber giving your dye the Maximum Absorbtion. You can also add urea to your dye to help give The Dye a more Vibrant look. I use appx 1/4 teaspoon per 4 ounces of dye mix. This is Assuming you are tie dyeing cold water procion mx Dye on 100% cotton Fabric. They do make cold water dyes for other fabrics such as polyester & Nylon but I find the colors just don't stand out like they do with cotton.I hope this helps you and best of luck with your tie dye Scott

is this item sodium carbonate, or sodium hydroxide?

It's sodium carbonate. This exact product is also sold as a swimming pool pH increaser. Sodium hydroxide, or lye, should not be used to tie-dye. Likewise, this product (soda ash) won't help you saponify oils for soap, or clear a blocked drain like lye will. Sodium Hydroxide, improperly mixed with water, can burn holes through plastic and cause severe tissue damage. Soda ash, mixed with water, will dry your hands out for a day.

please confirm that this is pure soda ash (aka: Na2CO3 sodium carbonate or washing soda) with no other additives... I need to raise my Pool PH

That's what it is, but you can buy the same thing cheaper (for swimming pools or as a fertilizer) if you need larger quantities.

What is volume ie. cups of package?

One cup weighs about half a pound, so this package has about 2 cups.

Seems good.

I don’t have experience of another so can’t make a judgement, however, it does the job.

Does the job

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
