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).

Silicon dioxide, also known as silica (from the Latin silex), is a chemical compound that is an oxide of silicon with the chemical formula Si O 2. It has been known since ancient times.Silica is most commonly found in nature as quartz, as well as in various living organisms.iliconâoxygen bond lengths vary between the different crystal forms, for example in Î±-quartz the bond length is 161 pm, whereas in Î±-tridymite it is in the range 154â171 pm. The Si-O-Si angle also varies between a low value of 140Â° in Î±-tridymite, up to 180Â° in Î²-tridymite. In Î±-quartz the Si-O-Si angle is 144Â°.
