Two-Colour Layering: Clean Boundaries, Soft Transitions

Steps

1. 01

   Mix the two batches 4 minutes apart

   Start the second batch once the first has begun to thicken — that gap is your working window.

2. 02

   Pour the first zone and stop short

   Fill to the zoning line and stop; letting it sit for 2 minutes gives a firmer base to pour onto.

3. 03

   Float the second colour in

   Pour over the back of a spatula so the new layer spreads without punching through.

4. 04

   Draw the transition

   For a soft boundary, drag a skewer once through the seam; leave it alone for a crisp line.

5. 05

   Seal flat

   Seal the dish before it fully cures so the boundary stays flush with the surface.
