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.
Silica (silicon dioxide) is a compound of silicon and oxygen (Si02). It is a hard, glassy mineral substance which occurs in a variety of forms such as sand, quartz, sandstone, and granite.It is also found in the skeletal parts of various animals and plants.ilica (silicon dioxide) is a compound of silicon and oxygen (Si02).

Silica (SiO 2) in sand and minerals in clay is used to make concrete and bricks. Silica, as sand, is also the main constituent of glass. Pure, crystalline silicon dioxide (quartz) resonates at a very precise frequency and is used in high-precision watches and clocks. Silicones are important silicon based polymers.
