In the migration studies, different temperature and contact time conditions were evaluated for the four selected food simulants. These conditions represented the following storage condition: (a) 20 c for 10 days: storage in a freezer or refrigerator; (b) 40 c for 10 days:long storage at room temperature or lower; and (c) 2 h at 70 c : long periods of usage. Table 2 shows the total silver released from the two containers under the different conditions assayed.
