LumniMarble™ Suspension Powder And Water Thickener will prepare your water for marbling. We use a mixture of food grade products to give you professional results. Our unique formula works in three ways. It makes your water dense enough to allow your paint to float, it contains a dispersant to spread your paint once it hits the water, and helps your paint to adhere to your skin with vibrant colors. LumniMarble™ Suspension Powder And Water Thickener will produce 25 gallons of solution, just add water. Non toxic.
