Maharaja Ram Singh gave Red Oxide color to the city of Jaipur and turned it Pink. In that time in whole of Europe Murano Italian Glass had become very popular and had been used in the Churches and Palaces. In Rajasthan (Rajputana) also it became a fashion to provide colorful Stain Glass in the palaces, temples and particularly in well known old houses specially in Shekhawati Area.
In Europe this Glass had been used with led soldering only, and the same work is done by the Artists there even today.

An examination of preserved specimens of medieval period reveals that most of them were made of small, convex pieces of glass that were cut from large blown glass globes coated on the inside with lead. Glass bubbles measuring between 50 and 60 cm in diameter were most often used for this purpose, and the blown glass was very thin. It is also evident that the lead backing was applied before the individual mirrors were created. The turner who made the mirror frames clearly knew that the mirror he was framing was convex because the central part of the wooden frame is often also convex. This examination also reveals parts of the manufacturing process. The glassmaker who produced mirrors must have started by blowing a large globe of glass similar to that employed in the making of traditional window glass. The bubble was then coated on the inside with lead. Later, the mirror glass was cut into the desired size. While these main features of production can be discerned, there are still many unanswered questions about how medieval glass mirrors were made.

The making of mirrors and the blowing of window glass were related activities. It was only natural, therefore, that the blowing of the glass and the making of the lead backing should take place in locations where glassmaking and the production of window glass had been established. In some cases, the mirrors were traded as semi-finished goods, and the objects were finished in the areas where they were sold. Throughout the medieval period, a lead alloy was used to back mirror glass. Lead was very suitable for this purpose, and it was easily obtained in most places. The backing of the glass with lead must have taken place when the glass was hot.

At the beginning of the 16th century; or perhaps a little earlier, this method of lead backing was replaced by a new technique, called amalgamation, in Murano, near Venice. At that time, Murano was a leader in the production of glass and mirrors. Amalgamation, which involved mercury and tin, was a cold technique used and another technique was called flat glass. Glass is blown continuously for six days until the furnace is empty. Two glassblowers work at one time in four-hour shifts. During one shift, they produce 60 to 70 pieces. At the end of the six-day blowing period, the furnace is allowed to cool down for four hours before new raw material is shoveled into the melting chamber.
