The best demos are less show, more craft. Here’s what to look for.
Signs of a quality demo
- A working glory hole and furnace rhythm (constant reheats).  
 
- Clear commentary on steps and tools (marver, jacks, tweezers, shears).  
 
- Teamwork: maestro + assistant(s), with synchronized passes and timing.  
 
- Real finishing — not just pulling a small horse for photos.
 
Class size and sightlines
- 8–15 people is ideal. You should stand or sit where heat and sound are safe but details are visible.  
 
- If the demo includes a hands‑on segment, it should be controlled and supervised.
 
The retail moment (and how to handle it)
- Many demos end in a showroom. That’s fine — but you shouldn’t be pressured.  
 
- If you plan to buy, take photos of labels and ask about hallmarks, origin tags, and return policies.
 
Safety and etiquette
- Follow distancing instructions; furnaces and punty rods are not props.  
 
- Ask permission before video; some workshops limit filming.
 
The best souvenir is understanding. Even if you don’t buy, you’ll leave seeing glass differently.
