Are these better at resisting that "coffee scum" build up that's so common on porcelain mugs?

Use any cleaner with bleach and coffee stains disappear in minutes then wash the cleaner off with dish soap. If you have hard water use CLR to clean the water stains off. It is best to immediately wipe glassware dry after washing and do not allow it to air dry.

Yes Ma'am! I'm using up my old ones presently. However, the ones I have are a little short, so must be careful not to overfill. In times of need I've used paper towels. BTW, I use two filters which makes the coffee richer in one way, and filters out more caffeine. Have fun!

Hi Jacqueline,That's a matter of individual perspective. I would not think that they're much heavier than a regular coffee mug - if at all. And they are certainly not fragile. I don't think anyone will notice a difference in weight. ENJOY!

Absolutely not. The exterior stays cool even with boiling water. Hot drinks stay that way for longer than with a ceramic mug though, so be aware of that.

Very good question. We have only used regular coffe mugs, therefore I am unable to answer your question. Hopfully others can help you out.

Well, I'm just displaying mine for the most part in glass-front cabinets -- ha! -- but I have washed the mugs in the dishwasher over and over, and there has been no damage whatsoever. That's been my only experience thus far.

Technically it is not. That being said - I have owned quite a few of these and generally run them through the dishwasher. However, my mugs have also all encountered an issue where the colored layer separates from the other layers - I'm willing to bet that is partly caused by dishwasher use.

I would think so. They are quite large though. I bought them to use for candles. We have poured hot wax into them and have had no problems. It seems to me that coffee would not be any hotter than candle wax. They are nice mugs.....but 16 ounces larger than most coffee cups. Hope this helped.

Yes I use these for coffee and hot tea daily. Wonderful mugs! I am glad I bought them.

I will use a stronger coffee and just put the same k-cup through the cycle twice. I can get a travel-mugs worth and it doesn't affect the flavor much.

I'm quite sure they are... don't think your dishwasher water will be hotter than the coffee.. ;) Maybe I should ask who the dishwasher is...lol

Yes, Suze, I have been using these mugs for about 10 years. They do chip as would any glass item but otherwise perfect. My husband is the one who usually chips the mugs because he is a bull in a china shop so to speak. I love the mugs.

No have not, use these all the time for perk type coffees and such. I do know that hot chocolate do not do well in these cups

Yes they do! I had a hard time finding the unbleached as well! They work for my Mr. Coffee 4 cupper! It's an old model - maybe 2005 or so.....is this helpful to you? Enjoy the unbleached flavor of the brew! Yes they are flat bottomed as previous reviewer mentioned!!!

I gave these as a wedding present to a couple I hang out with quite often, and they said they really liked them and used them often. They drink a lot of coffee. Therefore, I am assuming they are safe for coffee!

I've broken a few over the past 40 or so years and don't notice any difference in quality or tempering. I do put them in microwave full of water and heat to boiling for tea. I don't believe they are tempered like clear glass arcoroc mugs which I have seen bounce off a concrete floor without damage.

Honestly I don't think the heat would cause them to rupture. HHowever this is the only thing I wouldnt recommend them for. ...unless you've already iced the coffee and wanna use them to keep the coffee cool on a commute to work, etc. But these have held upto A LOT of wear and tear ....day in and day out. So I maybe surprised. Please let me know if u give this a try. :)Curious now lol
