Square Tray with Terrazzo
#v16864
Cast a square terrazzo tray. You start with a thin layer of casting compound that you then break into small terrazzo flakes. Afterwards, you use casting powder, water and craft paint for the tray itself. Once the tray has hardened, you remove it from the mould and sand it to reveal the beautiful terrazzo effect.

1 Start by finding the following for the terazzo flakes: 50 g resin cast mix and 15 ml water. For the mould, there is 100 g resin cast mix, 35 ml water and 5-10 ml craft paint.
2 Start by making the terazzo flakes. - Mix 50 g resin cast mix with around 15 ml of water. Set aside a little bit of the water to add if necessary for a thicker consistency.
4 After around 90 minutes, the mass should have hardened and you now break it into smaller flakes of 3-7 mm. Place the mass between two layers of plastic, for example, and use a hammer to break it.
6 Stir the coloured water into the resin cast mix – but first set aside a little bit. This can be used to make the consistency thicker.
7 Place a layer of terrazzo flakes smoothly on the bottom of the mould. Mix the rest of the flakes into the coloured casting compound. If necessary, thicken with a little water.
8 Pour the mixture into the mould. Prevent the terrazzo flakes from collecting on one side of the mould. Fill to 1-2 mm from the edge.
9 Make sure that the casting compound coveres the entire mould up to the edges all the way around by using the stirring stick to push it down on all sides.
10 Remove air bubbles by tilting the edge into the base all the way around – do this repeatedly for 2-3 minutes.
