Lampworked dichroic glass bead showing thin film application Furnace glass beads. A variant of the wound glass bead making technique, and a labor-intensive one, is what is traditionally called lampworking. In the Venetian industry, where very large quantities of beads were produced in the 19th century for the African trade, the core of a ...
They are also used as a material to increase the scanning range of barcodes in factory settings. The sheeting consists of retroreflective glass beads, microprisms, or encapsulated lenses sealed onto a fabric or plastic substrate. Many different colors and degrees of reflection intensity are provided by numerous manufacturers for various ...

Glass beads composed of soda lime glass are essential for providing retroreflectivity in many kinds of road surface markings. [1] Retroreflectivity occurs when incident light from vehicles is refracted within glass beads that are imbedded in road surface markings and then reflected back into the driver's field of view.

Crafting is big business. The global arts & crafts materials market was valued at $20.96 billion in 2022. And is expected to grow to $30.89 billion by 2030.More than three-quarters of American ...
Commercial retroreflective beads thus vary in index from around 1.5 (common forms of glass) up to around 1.9 (commonly barium titanate glass). The spherical aberration problem with the spherical cat's eye can be solved in various ways, one being a spherically symmetrical index gradient within the sphere, such as in the Luneburg lens design.
Indo-Pacific beads are a type of mainly tube drawn glass beads which originated in the Indian subcontinent but are manufactured widely in Southeast Asia.These are usually 6mm in diameter, undecorated and come in various colours for example green, yellow, black, opaque red, etc.
