Classmates Marbling Water Thickener
To create more distinct, clear marbling ink impressions, these granules can be added to water to act as a thickener. Add granules to clean water approx. 1 heaped teaspoon per 400ml. Leave for 10 minutes and then whisk until dissolved. Pour into a clean tray or bath to a depth of approx. 15mm. The thickener increases the surface tension, ensuring inks do not disperse to the same extent as they would with water on its own. 60g.
