Our quality standard
Quality & Materials.
Every Siruso Clear Goods piece is made from clean, lead-free glass and checked to a consistent quality standard before it’s packed. Here’s exactly what goes into our glassware and how we stand behind it.
What we make with
- Lead-free clear glass — tumblers, carafes, jars and vases with a smooth, polished rim
- Borosilicate glass — double-wall mugs and espresso glasses that handle heat with ease
- Heavy clarity-cut glass — decanters, mixing glasses and barware that catch the light
- Natural bamboo & glass lids — airtight seals for storage jars and canisters
- Tone-on-tone etching — our subtle frosted maker’s mark, etched into each piece
Lead-free & food-safe — tested
Our drinkware and food-contact glass is made to be safe for everyday use. Production runs are checked against recognized food-contact safety limits for lead and cadmium (in line with U.S. FDA guidance and California Proposition 65 thresholds), and our suppliers provide material and safety documentation for each run. In short: clear, lead-free glass you can pour into, drink from and store food in with confidence.
How every piece is checked
| Clarity | Inspected for bubbles, streaks and cloudiness — only bright, clear glass ships |
| Rim & finish | Every rim is checked to be smooth and comfortable, with no rough or sharp edges |
| Seal & fit | Lids, stoppers and bamboo seals are test-fit for a clean, snug close |
| Strength | Glass is selected to resist everyday thermal change and normal handling |
Caring for your glass
| Glass drinkware | Dishwasher-safe; avoid sudden temperature swings |
| Carafes & pitchers | Dishwasher-safe; hand-wash glass lids to keep them clear |
| Decanters & barware | Hand-wash and air-dry; use a decanter brush for the inside |
| Storage, canisters & vases | Jars dishwasher-safe; hand-wash bamboo lids; wipe vases clean |
