Questions About Vintage Glass Animals
  • 1stDibs ExpertNovember 4, 2024
    To identify vintage glass, you will need to figure out if your item is between 20 and 99 years old. The easiest way to do so is first to determine the maker by looking for and then researching any markings present on the glassware. Unfortunately, vintage glass is often marked with paper and foil labels, which tend to come loose with use. As a result, experience and expertise are often necessary to accurately perform the identification process, so you may wish to have a certified appraiser or experienced antique dealer weigh in if your glassware is unmarked. Find a diverse assortment of vintage glassware on 1stDibs.
  • 1stDibs ExpertAugust 8, 2024
    To tell if glass is vintage, first look for markings, often located on the bottom or inside of glassware. By researching the mark via online resources, you can determine the maker and learn more about your piece. Any glassware produced between 20 and 100 years ago qualifies as vintage, while older pieces are antique. In the event that you can't find any markings, a certified appraiser or knowledgeable antiques dealer can assist you. Find a wide variety of vintage glassware on 1stDibs.
  • 1stDibs ExpertApril 5, 2022

  • 1stDibs ExpertSeptember 9, 2024
    To tell if glass is vintage, first look for a marking that indicates the maker. By researching the manufacturer using trusted online resources, you can learn when it produced pieces similar to yours and get a rough idea of your glassware's age. Any glass produced between 20 and 99 years ago is vintage. If you need assistance with the dating process, seek the opinion of a certified appraiser or knowledgeable antique dealer. Explore a diverse assortment of vintage glassware on 1stDibs.
  • 1stDibs ExpertOctober 24, 2024
    To tell if your vintage glasses are gold, look on the nose bridge and the temples for a purity mark. Makers often stamped their solid gold pieces with “12K,” “10K,” “14K” and other markings to identify their gold eyewear. You can research all of these markings using trusted online resources. Should you locate a "GF" mark, it is likely that your glasses are gold-filled rather than solid gold. This means that the frames are predominantly a less expensive metal but do have a thin layer of genuine gold alloy as a finish. Another mark that indicates your glasses contain some gold is "RGF." The mark stands for “rolled gold filled.” Glasses bearing this mark feature a gold-plated finish that is thinner than what's found on traditional gold-filled frames. For assistance identifying your eyeglass frame material, consult a certified appraiser or experienced antique dealer. Explore a selection of vintage glasses on 1stDibs.
  • 1stDibs ExpertAugust 20, 2024
    To tell if a glass vase is vintage, first research the maker. Look for markings on the inside and base, and then research them using trusted online resources to determine who produced your vase. By looking at when the maker was active and producing pieces similar to yours, you can typically roughly estimate its age. If your vase is between 20 and 99 years old, it is vintage. Vases that are 100 years old or older are antiques. For help with dating, consult a certified appraiser or knowledgeable antique dealer. On 1stDibs, find a collection of glass vases.
  • 1stDibs ExpertSeptember 16, 2024
    Yes, some vintage glass is worth something. Collectors are often on the hunt for pieces produced by certain makers, such as Blenko, the Culver Glass Company, Dorothy Thorpe, Libbey, Georges Briard and Arcoroc. In addition to who manufactured it, the style, type, age and condition of vintage glassware all impact the potential value. For assistance with the valuation process for pieces in your collection, enlist the help of a certified appraiser or knowledgeable antique dealer. On 1stDibs, find a diverse assortment of vintage glassware.
  • 1stDibs ExpertAugust 29, 2024
    To tell if Murano glass is vintage, it's usually necessary to conduct some online research using trusted sources. Start by looking for a maker's mark and then cross-referencing it with images published online to determine who made your piece. By learning more about the manufacturer and what they produced over the years by reading histories and exploring product catalogues, you can estimate the rough age of your piece. For Murano glass to be considered vintage, it must be between 20 and 99 years old. Older pieces are classified as antique. If you need assistance with dating your glassware, seek the help of a certified appraiser or knowledgeable antique dealer. Explore a range of Murano glass on 1stDibs.
  • 1stDibs ExpertNovember 2, 2023
    To tell if vintage Cartier glasses are real, first look for the brand's logo on the outside of the arms. It should be spelled correctly and in the French luxury fashion house's iconic gold-toned italic font. Because some vintage pieces may lack serial numbers and other markings used to identify contemporary eyewear, you may wish to enlist the help of a licensed appraiser or knowledgeable dealer for assistance with authentication. Explore a selection of Cartier glasses on 1stDibs.
  • 1stDibs ExpertApril 5, 2022
    The easiest way to tell if a bead is glass or plastic is to feel it. Glass beads will be cooler to the touch, whereas plastic beads will be closer to room temperature and warm up quickly in your hands. Another test you can perform is to listen to the sound. Glass has a distinctive ring since it’s harder whereas plastic is softer and has a duller sound. Shop a range of vintage glass bead pieces on 1stDibs.
