Can it melt copper on a sunny day? Thanks!

Hello, the focal point of big lens can reach 1000 degrees under sunshine, but the melt temperature of copper is 1083 degrees, so i am not sure if it can melt copper, it affected by the size of lens and the condition of sunshine. You can try a bigger size such as diameter 400~500mm, we have even diameter 1000mm lens which can create 1000 degress in seconds, but the cost and freight charge is high.
