Unlike gelatine, agar does not exhibit an iso-electric point and is
negatively charged. This means that solutions of agar do not exhibit
maximum cloudiness and foaming at a specific pH. Agar jellies will set at
approximately 37° C (100° F) but considerably higher temperatures are
needed to bring about melting. In comparison to gelatine jellies, agar jellies
have a short texture but not so short as that produced using pectin. Agar
jellies take considerably longer to set in moulding starch impressions than
pectin jellies. Agar can be used in conjunction with all types of gelling
