Review on Schott Zwiesel Forte Collection Stemless Wine Glasses – Set of 6 Universal/Cocktail Tumblers, 19.1-Ounce, Tritan Crystal Glass by Randolph Iglesias

Have used these glasses 10 times. I've washed them in the dishwasher two or three times, laid them out clean and tidy, leaving just enough space between them and everything else so they don't rattle and they're in perfect condition. I usually hand wash these glasses because it's usually more convenient than a dishwasher. Last night while hand washing them I accidentally brushed the rim of a glass very lightly against the rim of the sink and it cracked! I was surprised it cracked because the contact was little more than a touch. Now my set of eight glasses is a set of seven. I believe these glasses are a bit sturdier than my Riedels (which will never survive the dishwasher) but they are still quite brittle and will break at the slightest touch if tapped "wrongly". They are also excellent glasses: elegantly shaped, transparent, with no yellow or green tinge, good size and quite a bit thicker than Riedel.
