Oase Copper Bowl. Made from copper, these high-quality fountain bowls will add a special aura to any garden. The components can be used alone or combined together on the optional copper base to suit your taste. There are a variety of bowl designs available – from square to round. Each bowl can also be illuminated from the inside using an LED ring. The warm 2800 Kelvin colour temperature adds a gentle shimmer to the water. The copper bowls gain further expression and charm over time as they form the patina typical of this metal.
