Real Murano glass carries evidence of making. Here’s your checklist.
Look for
- Credible labels and certificates — ideally backed by a known workshop.  
 
- Technique cues: cane lines, pontil marks, controlled bubbles (reticello), fine grinding.  
 
- Proportions and balance: thin lips, even walls, and secure feet in high‑level work.
 
Be cautious if
- Prices seem too low for complex techniques (e.g., large filigrana under market).  
 
- Every piece looks identical — handmade glass varies slightly.  
 
- Sellers avoid specifics about the workshop or maker.
 
Ethics and shipping
- Ask about returns, breakage policies, and international shipping.  
 
- Support workshops that train apprentices and pay fair wages — your euro sustains the craft’s future.
