wouldn't it be a rectangle with a handle attached? have you looked on any of the ceramic sites?

DH has used glass beer mugs for his coffee for years. He likes the large handles and the large capacity, and we hand test them before buying for good balance. We have had no issues with the glass and hot liquids. They do double duty as cold drink mugs as needed. I mostly use local hand thrown mugs, but with a similar capacity and similar handle shape.

My cameras disappeared over 20 years ago - foster kid who was short of money suspected. But one was an old 35 mm. model that used film, so it would have taken some finagling to have provided you with my mug shot, even were it still here and operational. So a verbal picture will have to do. Daughter gave me an oversized one, about three years ago, that's about the average height, but bigger around, so it is reasonably efficient at preserving the heat. When I get absorbed in some interest, though, on occasion some time elapses between drags/sips/whatever you want to call it. In which case, some treatment in the microwave brings the contents back up to a condition that one considers appropriate. It has a desert scene, largely in variations of beige and brown, as a background, with large raised letters "A r i z o n a" in fairly large letters, darker brown, going pretty well all of the way around the mug. Some would only want the dark brown of unadulterated coffee within ... ... but my preference is for some sweetness (more than I have available on the inside) .. ... and some cream (being a long-ago graduate of the farming training school of hard knocks) ... ... so the liquid inside of my (exterior) mug is rather a beige colour, that complements some of that on the outside of the mug. As to what colour it may be on the arrival inside of my mug ... no one has ever investigated that ... but I assume it to be similar to the colour that it was in the (exterior) mug. ole joyfuelled ... with a little help from coffee, from time to time

I had a post show up on my Facebook feed this morning about coffee mugs. It was quite interesting. It was a video and it said a cup of coffee is like people. It isn't what is on the inside (the coffee) we look at. It's what's on the outside (the cup). And by choosing what's on the outside, we could quite possibly miss out on something really good on the inside, as the cup we drink from, often hides what is inside of it. Just like a person: we visibly see the person, but we don't see what's going on inside the person. We could very well just miss out on a very good person if we don't like what we see on the outside. I wish I could post it here.
