“…Meanwhile, in the developed nations like Europe, glazed pottery containers are used to pack high value, luxury foods such as very expensive marmalade, meat paste and cheese (Fellows and Axtell, 1993). Correctly glazing the earthenware can make them much more suitable for Jam packaging, as such glazed pots are very resistant to chemical attacks (Silva et al, 2012), have low permeability to moisture (Harper, 2012) and gases, and have little interaction with the product contained within it. Acceptable sealing methods for pottery packaged food products include use of cork bung (around which sealing wax is coated), use of pottery insert and disc of polythene, and waxed paper or polythene held on with rubber band or string (Fellows and Axtell, 1993).…”
