use alginate as water-based resist?

can i make sodium alginate thick enough to use as a resist?

i'm trying to develop a homemade resist for silk painting (etc) that isn't mind-bogglingly complex like japanese rice paste.

i'm not interested in using wax.

i tried blue glue. it wouldn't come out until i'd already boiled the dye away.

i tried tapioca starch. it didn't resist at all, and wouldn't come out without serious scrubbing.

i've heard about flour paste for use with small kids, but haven't tried it.

anyway, i've read that there are problems with starch resists. i can believe it. but what else can i use? i've had great results with sugar syrup, but it's only a partial resist, and i use it in order to on-purpose violate it for the interesting ferny effects it gives. but it won't do for this: i need something that's a full resist.

whatever, i'm not willing to pay $10 for a 4-ounce bottle of proprietary stuff any more.

alginate as resist

yes you can use alginate as resist,provided you do not do immerse the fabric for dyeing.
however if you're going to do silk painting and use an acid activator or medium the alginate will curdle.therefore it's best to use gum arabic as resist. i've used both and they work well,gum arabic is more difficult to remove, but no big deal. go here http://amovablefeast.blogspot.com/2007/06/gum-arabic-resist-tutorial.html for a short tute i did on gum arabic.
hope this helps

eureka

to report on my experiment with sodium alginate as a water-based resist - SUCCESS!

it made sharp lines; the lines held. it resisted many applications of dye on both silk and linen without breaking, and it worked just like no-flow when painted on. plus, it washed out easily.

so all in all, i think i have found a cheap and easy replacement for water-based resist.

i've detailed it on my blog - fabricart.wordpress.com

That's wonderful, Jeanne. So inexpensive and practical!
