In the XV Century, glass arrived in Peru brought by the Spaniards in the form of mirrors and picture

frames destined to decorate churches, convents and houses of the time. Also, they brought beads from Murano, an Italian island next to Venice, where the greatest production of glass and crystal, between the XVIII and XIX, took place.
The Spanish technique of stained glass windows, of great Arab influence, were copied and modified by Peruvian craftsmen. They developed new regional styles, such as the andahuaylino (reverse-painted glass frames), the cajamarquino (thoroughly painted glass), the Cusco style (carved wood frames that include painted glass), the mixed style or cuscaja (using gold leaf on the carved picture
frames and on painted glass) and the polychrome style (using multiple multicolored hues). These styles can be observed in museum collections, in decoration of church altars and convents of different regions of the Perú.
