• Carnelian Glass - Carnelian glass is a type of glass that is colored red, orange, or brownish-red. It is made by adding iron oxide to the glass mixture. The color of carnelian glass can vary depending on the amount of iron oxide that is added, as well as the firing temperature. Carnelian glass is often used to make beads, jewellery, and other decorative items. It can also be used to make stained glass windows and other art objects. Carnelian glass is sometimes called "carnelian chalcedony" or "carnelian quartz."
  
  Carnelian glass was first made in the Roman Empire. It was also made in ancient Egypt, Greece, and Mesopotamia. Carnelian glass was not made again until the Renaissance, when it became popular again. Today, carnelian glass is made in many countries around the world.

• Heraldic Decoration - Heraldic decoration on silver, glass, and porcelain refers to the use of coats of arms and other heraldic symbols as decorative motifs on these materials.

  The heraldic decoration typically takes the form of engraved or etched designs that incorporate coats of arms or other heraldic symbols. Heraldic decoration on silver, glass, and porcelain has a long history, dating back to the medieval period when coats of arms were first used. During the Renaissance and Baroque periods, heraldic decoration on decorative objects became increasingly elaborate and ornate, with finely detailed designs that often incorporated intricate scrollwork, mythological figures, and other decorative motifs.
