COOL VESSEL
To make an in-vogue bowl, start by combining packaged concrete mix and water according to manufacturer’s instructions. Stir in black pigment powder (from bunnings.com.au) to achieve the desired charcoal hue. Spray inside of a large plastic bowl with non-stick cooking spray and spoon mix into bowl, filling about three-quarters full and tapping to remove air bubbles as you go. Spray the outside of a smaller plastic bowl with non-stick cooking spray and press it into the centre of the mix, pushing the concrete toward the rim of the large bowl. Weight the small bowl with rocks. Let set. Remove concrete from bowls; sand any rough edges, if desired.
