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, or silica, is a. polymeric solid with a three-dimensional network of silicon atoms bound in a tetrahedral. structure to four oxygen atoms, each of which are bound in turn to two silicon atoms. (Figure 13.1). In silicate minerals, this network is rearranged to accommodate other. metal oxides.
