It's not a gelling agent like u need for marbling. It still works but not as good.

I've been purchasing jacquards 4oz bag for years. I'm a professional marbling artist. Two sessions a week every week. Jacquards lasts me a month. This one lasted me two weeks and STILL did not thicken the water fully. It was possible to marble on it but the water was far thinner than it should have been. I'm skeptical this is a full 4oz as well. Really small container for 4oz. I think they might be counting the weight of the bottle with the product. I was really disappointed and felt like I wasted my money.
