Advice? The ratio's were 2g Sodium alginate to 200 g liquid.

But when I tried to order, he started asking about mesh and stuff. Any idea what is that? I have a local supplier selling Sodium Alginate, food grade.

In Europe some gourmet/specialty food shops do stock the Texturas series or similar products from texturePro, Kalys or other vendors. Regarding prices, my best advice is to check what the internet suppliers charge. This should give you a good idea of what the selling price is.

Non-edible sodium alginate is way cheaper. Does anyone know if it will still work in an experiment? I'm making Instant Worms for second graders! Please help!!! Hi,

Just stumbled upon your blog randomly and I would like to say awesome post and video. Looks dead easy; now I need to get my hands on some sodium alginate and calcium chloride :) Thanks for sharing Hi!

I substituted strawberry soda for the cola and ended with something that resembled Flying Fish roe. I had one down side and that was due to the calcium chloride bath. The spheres had a salty taste on the outside when you first put them in your mouth. I was using food grade calcium chloride and I even rinsed off the beads and let them soak in a larger bowl of water and they still had that salty taste on the outside. Any advice?

So use 2 grams of Na-Alginate in 100g water. You dont even need to use a blender to dissolve it. At about 40 degC and continuous stirring, alginate will dissolve in about 20-30 minutes. There will be less bubbles hence, less waiting time. Also the calcium chloride drop should also be at least 2% (w/v). Hope this helps Joe,

When I injected the alginate solution into the bath nothing happened. This was my first attempt at this and I don't know if my formula is bad, is soy is not a good substance for this process or if my scale was inaccurate. Can someone review the above and give me dome idea as to where I went wrong. I tried to make spheres from soy sauce using the following formula:
1 g sodium alginate
100 g water
25 g soy sauce
1.25 g calcium chloride
250 g water
