Sodium Alginate is pure kelp (seaweed) - it's commonly used to thicken food. It is the most economical thickener for Dharma's Fiber Reactive Dyes and it works as a thickener for other liquids as well. Use whenever you want to use dyes more like a paint. You can then brush the dyes on and they will stay put, as well as stamping, stenciling or silk screening the dyes. Dyes are more work than Paint to use in these methods, but the reward is, they leave absolutely no feel on the fabric the way paints can.

Sprinkle the thickener into the chemical water or liquid dye slowly, mixing continuously. (You can also use a blender - add the alginate through the top with the blender going). Let sit for an hour or so to continue to thicken before use. Refrigerate to store. Don't over-thicken, thinner is better.

We have two kinds: High viscosity, low solids for cotton, and Low viscosity, high solids for silk. The silk one allows you to draw finer lines but requires you to use more.
You can use them interchangeably. Specify which one you prefer.

Not recommended for thickening Paints.

Dharma's Sodium Alginate is so much more concentrated than other's I have used. It was a great surprise that I only had to use about half the quantity I used with other brands. I highly recommend this product for silk screening and dye painting.

Very useful for thickening fiber reactive dyes. I've used this for thickening dye into a gelatinous consistency to paint on black dye for a stained-glass effect--works great!

I think this works well to thicken my dyes but it's difficult to dissolve it. They suggest putting it in the blender but I haven't done that. I just shake the heck out of it!

Works almost too well. You have to be very careful not to put in too much. I use the dyes to screen print so I need them a bit like "Jelly" but there's a fine line!!! Great product!!!

This is my first time to use the sodium alginate. It was not difficult to mix using a blender bought just for that purpose. Was so much fun to see the difference in adding the dyes to the sodium alginate. Gives my hand dyeing experience a whole new facet. i love it.

might have given this a great rating but I'v only just begun using this and therefore am still experimenting.overall does thicken the dyes well,it seems although it did'nt make my dyes as thick as some described it would maybe it is because we have soft water.

This is wonderful to have! It does not take much of this to thicken the dye.. and it takes a while to dissolve, but it is wonderful for mixing with the dye, if you use it to write on fabric or draw fine lines.

Using this product for the first time can be very TRICKY! I put way too much in my dye mixtures and it was very frustrating and clumpy. However, with time and using a bit more sparingly - I suppose I'll get the hang of it. I can see where this product can be very helpful in thickening the dyes and helping in control those annoying little splash marks that sometimes happen when using the squeeze bottle tie dye method.

As public school art teachers, my wife and I teach kids to tiedye and thickening our Procion dyes makes it much easier for the them to have success right from the first shirt, no matter what age/grade level. Since alginate is the same thickener used in ice cream and comes from sea weed, that just adds to the cool factor for them.

This worked well. It was a little difficult to get it to dissolve. The blender solved that problem. If you don't mind it being a little lumpy you can mix it by hand. I was in a hurry and mixed a small amount by hand and the lumps didn't seem to affect how the dye worked on the fabric.
