Question: Do these glass mugs come out of the dishwasher stain free?
Document: Received in good condition, and on time. One mug has small bubbles in the glass, perhaps a second that made it thru the inspection process. These are great for my everyday coffee, tea and come thru the dishwasher clean and sparkly.
Maybe I need a new dishwasher but all my ceramic mugs stain badly from the tea we drink. I even tried using twice the amount of dishwasher detergent (an expensive option)  but those darn mugs still came out stained. Since my dishwasher cleans everything else properly I wondered if I could solve the problem by using glass tea holders the way they do in some parts of Europe. When I googled glass tea mugs these came right up.
I mostly love these mugs. The only thing I loathe, which is true of most mugs, is the dip on the bottom that fills up with water in the dishwasher. This is quite an annoyance when taking them out.What I love:-Big-Handle is comfortable-Made in USA-Lead free-No need for a coaster with it having the base
I love to use glass mugs, but it is extremely hard to find LARGE and DURABLE glass mugs out in the shoppes. Honestly, I have almost never come across large, durable, and reasonably priced glass mugs in the shoppes. These 16-ounce mugs are perfect for what I was looking for. They are large, durable, and easy to clean, and despite what some reviews have said, there is nothing about them that is uncomfortable while holding them.
Well made and sturdy mugs, wash easy in dishwasher. They are made of pretty thick glass therefore they may last for quite a while. Must admit edges and seams of the glass are not extremely refined like some other mugs but it doesn't bother me at all. They have grayish tint to the glass since they made of thick glass so it's notcrispy clear as some much thinner versions.
Large, strong & sturdy mugs! I love being able to use the full 16oz for extra strong Keurig Dark roasts as well as having extra space for foam with hot chocolates. The handle is great and the cup is easy to hold from the bottom, the side or even under the lip. After several washings in the dishwasher the glass is still crystal clear. The only con for some might be the extra space they take up in the cupboard! Highly recommend
I like drinking my tea out of clear glass, and these are a great value. The only negative is that, due to their shape at the bottom, there is water left over in the bottom (of the outside) once the dishwasher cycle is done.
I bought 6 of these mugs from Crate & Barrel, also made in USA. $3.95 each and free shipping. Amazon pricing used to be the best. I have not found the seam problems others noted with the Amazon product.
It's the style I was looking for and the fact that its made out of glass which is a very safe product to drink hot liquids from. The only I do not like about it is when it in the dishwasher it collects water in the base making it a bit tricky to get out of the dishwasher without making a mess.
These glasses are thick, dishwasher safe, and durable. They don't have any of the sharp edges people talked about in the reviews. They were packaged very well and none of them were broken. I bought two boxes. I have even used them to make the alcoholic beverage called Spanish Coffee and I lit the alcohol on fire right inside the glass after the glass had been heated in hot water and the glass withstood the short burst of heat from the fire.
Answer: So far ours have - had them for about 3 months.
