There are many palaces in Rajasthan where the doors are inlaid with ivory in intricate floral or geometric patterns. The same craftsmanship is found in thrones, howdahs, and horse or camel saddles. Mirror-inlay work on wood is of Persian origin. Here the glass is blown by the craftsperson at the site of decoration and while it is still hot mercury is poured in to mirror the concave insides. Then the blown mirror-glass is broken into small pieces and shaped according to the pattern drawn on the wooden wall. These are fixed with plaster or lime.
