Grills or Jallies as they are called in India are widely
used all over the world as shade screens, security grills, dividing walls,
banister screens, fence lines, window screens, table plates for glass tops,
and in buildings where there is a need for ambient lighting or temperature
control. Traditionally seen in foyers, patios, courtyards, or gardens, they
can be used ornamentally and architecturally.
Jallies can incorporate art nouveau, art deco, Mediterranean, and a host of
other design motifs, apart from the more usual Persian geometric themes.
Often they are at least one to two inches thick, and cannot be broken
easily. The stone is structurally stronger than cement. A dramatic context
for jallies is a setting where sunlight or nightlight shadow patterns are
stretched along the floor and opposing wall of the light source.
