Abstract

Curved brass trough, roughened surface when exposed to sun light heat generated due to multiple scattering occurs and rough surface absorbs more light in comparison to plane& glassy surfaces. (by lessening specular reflection). Heat generation in trough type surface to UV rays path changing and more absorption of light. Brass tarnishing/oxidation filmy surface UV rays absorption more leads higher temperature above 120 degrees in normal sunshine and at winter part cloudy sky for cooking.
