Whitefriars and Murano Glass Vases, 1964 and Later

• Aventurine Glass - Aventurine glass is a type of glass where small flakes of gold, copper, or silver color form in the glass and provide a glitter or sparkle to the glass when seen in the light. The small flakes are created by adding copper, gold or silver to the molten glass during the glassmaking process.
• Oviform /ovoid - The outline loosely resembling the shape of an egg.
• Circa - A Latin term meaning 'about', often used in the antique trade to give an approximate date for the piece, usually considered to be five years on either side of the circa year. Thus, circa 1900 means the piece was made about 1900, probably between 1895 and 1905. The expression is sometimes abbreviated to c.1900.
• Inclusions - Inclusions in glass objects refer to small, often irregularly shaped particles or bubbles that are trapped within the glass during the manufacturing process. These inclusions can be intentional or unintentional, and can range in size, shape, and composition.
  
  Intentional inclusions are often added to the glass for decorative purposes, and can include materials such as colored glass, metallic foils, or even small mementos like photographs or other objects. These intentional inclusions are typically added to the glass while it is still in a molten or semi-molten state and are then moulded or blown into the final shape of the object.
  
  Unintentional inclusions, on the other hand, are typically the result of impurities or air bubbles that become trapped within the glass during the manufacturing process. These inclusions can be seen as small specks or bubbles within the glass, and can sometimes be a sign of poor quality control during production.
  
  While intentional inclusions can be a desirable feature of some glass objects, unintentional inclusions can sometimes be seen as a defect, and can reduce the value of a piece. However, in some cases, certain types of unintentional inclusions can actually increase the value of a piece, such as with antique glass that contains bubbles or other imperfections that are characteristic of the time period in which it was made.
