Product & Design
Why can glasses of the same type sometimes look different?
This is the essence of our brand philosophy: an ode to craftsmanship . Variations in wall thickness, feel, or the presence of tiny air bubbles are not defects. They are proof of the craftsmanship and make your unique piece truly one of a kind.
Are the glasses free of harmful substances and safe for contact with food?
Yes, our high-quality borosilicate glass is free of harmful substances , lead-free , and safe for permanent contact with food, acids, and bases. The material is also used in laboratory and medical technology.
Why are these glasses more robust than conventional glasses?
By using borosilicate glass 3.3, our glasses are significantly more resistant to mechanical impacts and thermal stress. This material is characterized by its low thermal expansion, making it ideal for everyday, long-lasting use.
What do the small grooves visible in the bowl of the glasses mean?
These subtle grooves are a specific characteristic of the mouth-blown process and bear the glassblower's signature . They attest to the authenticity and manual rotation during the shaping process and are part of the unique character of each piece.
What is special about the stem?
The stem is the soul of the glass and a central, unique feature of Casa Vitri. We use colored borosilicate glass for the stem, which is fused to the transparent bowl in a complex process.
1. Unique color: The fusion and handwork create unique color nuances that make each stem unique .
2. Stability: The colored borosilicate glass ensures a stable, durable appearance and perfect balance . The stem thus guarantees the robustness of your glass in everyday use.
Care & Service
Is my glass dishwasher safe?
Yes, absolutely. All casa vitri glasses are dishwasher safe . We use borosilicate glass 3.3, a high-performance material from laboratory technology. It is extremely resistant to chemicals and heat.
Ideally, place your glasses in the top rack of the dishwasher and use the glass holder if your dishwasher has one. We recommend, of course, positioning the glasses so they don't touch other objects to prevent damage.
For best long-term care and to optimize energy efficiency, we recommend programs in the range of 50°C to 60°C (e.g. Eco program).
If you have extremely hard, calcareous water in your region, we recommend using a dishwasher descaler and regularly checking the salt level.
