Elaborately decorated metal feet and stems onto which ordinary glasses can be clamped thus forming an elegant vessel. They were made as prestige objects to adorn the table. In the 15th century glass holders were often commissioned by city councils and aristocrats. By the 17th century, wealthy burghers had acquired a taste for these objects, although the fashion declined after 1650. Most glass holders were made of bronze, silver or silver gilt. The clamps often incorporated a human figure, a sea-horse or an animal head.

Visual works, often windows, or components of visual works or architecture, made of bits or pieces of glass, often chipped along the edges to resemble faceting, set in a matrix of concrete or epoxy resin. The first glass in concrete windows appeared ca. 1929 in Europe; the technique is now used to create other objects as well. For cement reinforced with glass fibers, use "glass reinforced cement."

Process of creating windows or other visual works using glass in cement or another matrix. Pieces of glass, usually slab glass, are laid out in a design or pattern; the pieces of glass may be cut, shaped, and chipped along the edges to resemble faceting. Cement or another material is poured between the pieces of glass, often with metal reinforcements, and allowed to harden.

Un tinte azul oscuro natural obtenido de las hojas de la planta biennial Isatis tinctoria. Fue cultivada desde tiempos tempranos como un colorante textil en Inglaterra, Francia, Grecia, Italia, Egipto y China, y fue utilizado como un pigmento de pintura en la Edad Media.

El color azul se profundiza con la edad de la planta, que va desde un azul claro en las hojas jóvenes a un negro azulado oscuro en las hojas completamente maduras.

Un mineral mica opaco verde compuesto de silicato de hierro de potasio hidratado, que - a diferencia de otras micas - por lo general se presenta como granos tipo pellet en ambientes marinos y es a veces llamada "tierra verde". Se forma a partir de la alteración de silicatos que contienen hierro por el agua del océano y de los organismos, se encuentran a lo largo de la costa atlántica de la América del Norte y del Sur y en el fondo del océano, ya veces se utiliza como pigmento para pinturas de tierra verde.

Genus containing around 12 species of locust trees.

Species of thorny tree native to regions in North and South America, Africa, and Asia. It produces a high quality wood. The long thorns were once used as nails. Currently, honey locusts are mainly grown as an ornamental tree; its slow growth minimizes potential for commercial use. It is not a significant honey plant; rather the common names derive from the sweet tasting pulp of the legume fruit, which was used for food by Native Americans and is fermented to make beer.
