Some useful tips for splash design: 1. If you dont have black jesmonite pigment, you can use black acrylic inc (or other black water-based ink). It is much more pigmented compared to acrylic paint. 2. When you make splashes, let it dry approx. 10 min before pouring. Its very important! 3. Demould your tray not late than 30 min after pouring (it helps to prevent sweating). 4. Let it dry 20 hours and seal.
