CARE & MAINTENANCE
Glassware Care Guide
Hand-blown borosilicate looks delicate. It is built for real daily use when cared for correctly.
Material: What You Are Holding
Every Vitra piece is hand-blown from borosilicate glass, the same material used in laboratory beakers and premium cookware.
- 3.3x more thermal shock resistance than ordinary glass.
- Higher surface hardness for long-term clarity.
- Chemically inert, so it will not absorb flavor, stain, or leach.
Daily Care: Drinkware
- Dishwasher top rack is safe for single-wall and double-wall cups.
- Microwave safe when no metal trim is present.
- Boiling tea, espresso, and iced drinks are fine.
- Hand wash with normal dish soap and a soft sponge.
- Avoid direct flame, steel wool, harsh cleaners, wet stacking, and hard drops.
Candle Holder & Oil Lamp Care
- Freeze holders for 30 minutes to remove solid wax cleanly.
- Use hot water, dish soap, and non-scratch sponge for residue.
- Never scrape wax with a knife or metal tool.
- Use paraffin-based lamp oil and trim wicks before lighting.
- Extinguish oil lamps by snuffing instead of blowing.
