What is Tritan?
Tritan is the name Schott Zwiesel gave its lead-free crystal glass in 2000. Instead of lead oxide, which traditionally gives crystal its brilliance and weight, it contains titanium and zirconium oxides. This makes the glass just as clear and gives it the same lovely ring, but makes it harder, lighter, and more resistant to scratches and dishwashing.
Don't confuse it with Eastman's Tritan plastic, used in unbreakable glasses. Read more about it in our article on Tritan or polycarbonate. Schott Zwiesel's Tritan is real glass.
The difference compared with lead crystal
Lead crystal is soft: it scratches, becomes cloudy in the dishwasher, and has a thicker rim because the glass is fragile. Tritan crystal glass can be blown thin and still withstand hundreds of wash cycles without becoming cloudy. Schott Zwiesel guarantees that it stays clear. You can see this in practice in restaurants: the Tritan ranges last for years in commercial dishwashers.
The sound when clinking is clear, the rim is thin and the stem is strong. Most people can't see the difference compared with lead crystal, but they can notice it when washing the glasses. Read more about the materials in our article about crystal glass.
Who is it worth it for?
For anyone who uses wine glasses every day and wants to put them in the dishwasher. For the hospitality industry, where breakage and cloudy glasses cost money. And for anyone who wants a beautiful range that will still be available to buy ten years from now: the major Schott Zwiesel ranges, such as Banquet, Classico, Taste and Belfesta, remain available for years.
Other manufacturers make similar crystal glasses under different names: Spiegelau with Platinum glass, Chef & Sommelier with Kwarx, and Royal Leerdam with Signum. They look alike; when choosing, pay attention to the shape and size that suit your wine. You can find all the ranges in our wine glasses.
The right glass
The Schott Zwiesel Banquet wine glass holds 47.5 cl and is an all-purpose red wine glass made of Tritan that can go in the dishwasher every day. The Classico glass holds 40.8 cl and has a classic tulip shape. Find all collections in our wine glasses collection.

Good to know
Can Tritan crystal glass go in the dishwasher?
Yes, that's the whole point. Use a glassware cycle, space the glasses apart, and leave the door open afterward. Read more in our article about glasses in the dishwasher.
Is Tritan unbreakable?
No. It is more resistant to breakage than regular glass, but it is still glass. It won't survive a fall onto tiles.
Zwiesel Glas or Schott Zwiesel?
The same company. Since 2020, the brand has been called Zwiesel Glas; Tritan glass is now called Tritan Protect.
