Why is Greek pottery orange and black? The bright colours and deep blacks of Attic red- and black-figure vases were achieved through a process in which the atmosphere inside the kiln went through a cycle of oxidizing, reducing, and reoxidizing. During the oxidizing phase, the ferric oxide inside the Attic clay achieves a bright red-to-orange […]

This higher frequency of vibration means that the air particles around the string carry a higher frequency sound wave to your ear, which perceives the higher frequency as a higher pitch. What happens if […]
