Sieve chemistry

WebThe sieve retains larger particles. Sieving is the process of using a sieve to separate materials of various sizes of materials. With the support of a netting or perforated bottom vessel through which the material is agitated or poured, the material is exposed to mechanical forces of vertical and lateral movement. Websieve n. (separating net, strainer) setaccio nm. The gold hunter used a sieve to strain the contents of the river bed. Il cercatore d'oro usò un setaccio per filtrare i contenuti del letto del fiume. sieve n. (for powder) colino, vaglio nm. Larry poured the flour into a sieve.
