Based on your description—made entirely of glass with narrowed openings all around the perimeter—it sounds like you may have found a glass flower frog.
Here’s why:
What a glass flower frog is
- Material: Glass (sometimes ceramic or metal)
- Shape: Usually a flat or slightly domed disk with multiple small holes or narrowed openings
- Purpose: Used in floral arrangements to hold stems in place inside a vase
- How it works: Each stem is inserted into one of the small holes, so flowers stand upright and arranged neatly
Other possibilities
- Glass spice or herb strainer/caddy lid – if the holes are tiny, it could have been used to sprinkle powders or seeds.
- Perfume or potpourri diffuser – some antique diffusers had perforated glass tops for fragrance dispersion.
- Decorative object / antique puzzle container – some vintage glass items had multiple openings for aesthetic or functional purposes.
✅ How to check
- Measure the holes: Are they big enough to fit a flower stem? → Likely a flower frog
- Check the base: Flat to sit in a vase? → Confirms floral use
- Look for markings or patterns: Antique glass flower frogs often have pressed patterns or brand marks
If you want, I can show you pictures of antique glass flower frogs to compare with what you found, so you can identify it for sure.
