Re: [Marbling] Re: Marbling in heat
- We also carry a seaweed based size up in Canada called Sodium Alginate. It's
in a powder form which you blend together with water to make the size. I
started marbling with this size originally and found it to be much more
viscous and thick than the carrageenan. I do agree that the carrageenan
gives a much more clean look but I may try the sodium alginate again this
weekend to see if it makes a difference in warm weather...has anyone else
tried this product and what do you think of it? I liked it BEFORE I
discovered the carrageenan...but I still do use it on occasion.
