This is how the beautiful bowl is designed:
First spray the inside of the planter with baking spray.
Mix 60 tablespoons of concrete with water to a creamy mixture and pour it into the planter. Spray the outside of one half of the acrylic sphere with baking spray and press it into the mixture. Weight down/fix the hemisphere. Leave to dry for 24 hours.
Then remove the hemisphere from the mass. Bend the planter shell slightly outwards to loosen the concrete. Carefully invert the tray. Remove the casting.
Mix the plasticine according to the instructions on the packet. Turn the concrete bowl upside down (opening facing down) and moisten the rim with water. Shape the plasticine around the rim of the bowl. Use the Dot Painting wooden sticks to press a pattern of your choice into the concrete. Leave to dry for 24 hours.
