High quality extra carrageenan in powdered form, to make marbling water (‘size’). Extracted from Irish Moss / Carrageen seaweed; non-toxic and food-safe.
Suggestions on how to prepare;
Blend 20g with 3 litres of water to make enough to fill an A3 marbling bath.
I recommend leaving the size overnight, or at least 6 hours, in the fridge to settle after blending. Store carageenan powder in a cool, if you could fridge that would be best, dry place away from sunlight.
