EISCO Premium Hand Crafted Beaker Mug, Thick Borosilicate Glass, 8.4oz (250mL) Capacity - Small Size - Tea or Espresso Sized

Love this nerdy mug! The glass feels very solid and the graduations on the mug are printed very clear. Love to wake up in the morning and show my love for science while drinking my coffee.

This cup-beaker holds exactly 250 milliliters (one quarter of a liter). The cup is marked in five parts, i.e., in 50 ml increments (50, 100, 150, 200), which are practical for any use. The markings are in a large, white contrasting font, so it is very easy to read. There are no confusing obsolescent ounce markings, which require mental calculations dividing by 2, 4, 8, etc. The beaker can also be used to measure solid foods in convenient milliliters. The pouring lip is handy for pouring water into coffeemakers, which often have narrow intake areas. The total capacity of the cup, 250 ml, is perfect for a cup of coffee. A glass of wine is defined for nutrition or DMV purposes at 150 ml. Thus, you can pour an exact "glass," which is a little more than half of the capacity of this cup. If you are not drinking wine in a formal setting, you can use this handy cup-beaker, at your computer desk, for example, without risking an unstable wine glass falling into your keyboard or, worse, your CPU!

smaller than I thought, but still love it. I got lots of compliments at the office.

Yes, it's not as large as you think (slightly smaller than a normal mug for coffee), yet it's not as small as some of these people describe it. You can easily get a solid amount of coffee in this thing for the morning. Overall, very sturdy, yet I wouldn't call it "thick." It's not thin where you'll be scared to bump it around in the sink. Packaged well, yet mine came with small specks of black stuff on part of the rim when I looked closely. It was hard to get off and didn't get all of it off. TL;DR Sturdy, not as large as your normal mug, overpriced in my opinion.

I'm using this to heat up milk in the microwave for cappuccinos. I thought for sure the metal frother would scratch the heck out of it but it still looks brand new after two months of almost daily use. This is a tiny mug so it's a bit expensive in my opinion and I would deduct a star for that but because it's held up so well, I'm going to keep it at 5 stars. Sometimes you do get what you pay for :-)

It's absolutely more fragile and weaker than advertised. It works great as a little shot mug for espresso machines, etc but when I place a metal utensil in this to stir the coffee it feels as though I'm one sleigh bell away from shattering this and the hot liquid all over. It's perfect as a white-elephant or peer/colleague gift if you're in a related field - would look great as a pen holder in an office, or such, but feel unusually fragile to be a daily go-to for hot beverage.

This is a very nice cup for drinking my coffee or tea when take a break at school or even when I'm in a meeting with my colleagues. As a chemistry teacher, this item is a particular and original distinctive.

Perfect for the science geek in your life. Great gift. I'd really love a 350mL beaker to hold more tea/coffee, but this is pretty cool.

Got this for my chemistry teacher, she loved it and I’d recommend it to anyone.

Love it
