Food processors are more appropriate for solid foods, which cannot be effectively ground with a food mill, such as cheese or nuts. The food ground in a food mill must be soft, often being steamed, baked, or boiled before being processed.

Chemistry: Silica, also known as silicon dioxide, is a compound made out of the two most abundant elements in the Earth's crust, silicon and oxygen (SiO2). Silica has three main crystalline varieties: quartz (by far the most abundant), tridymite, and cristobalite.hemistry: Silica, also known as silicon dioxide, is a compound made out of the two most abundant elements in the Earth's crust, silicon and oxygen (SiO2).
