Hi Rahul,

    If the shellac you use is similar to that used in the US, it's not
    necessary to heat it to remove it. 

    Shellac is soluble in alcohol. Place the item to be removed in a
    container of alcohol & let it soak for a time. In the US  methyl
    alcohol  (denatured alcohol) is used by many folks. 

    There are also mechanical holding devices for holding things like
    rings, bracelets, earrings, etc. Pictures & descriptions in a good
    tool catalog would illustrate the wide selection of tools unique to
    the jewelry trade. A couple of good books, 'The Theory & Practice of
    Goldsmithing' by Erhard Brepohl & 'Jewelry Concepts & Technology' by
    Oppi Untracht will also provide some insight into tools & the
    reasons for why some things happen & the way they are done. These
    books are available from most jeweler's supply companies in the US,
    online from various book sellers & probably in the international
    market. 

Dave
