Are these cups vitrified or restaurant-grade for high-heat dishwashers? Thank you

Hi Just Wondering, The only answer I have for you at this point is that the box says "dishwasher and microwave safe". I do not know if they are a grade for High Heat dishwashers. You might be able to find some info by contacting the producers of the Rachel Ray mugs. Sorry I don't have a better answer for you. Cheers, Dave

I put them in the dishwasher. My dishwasher does melt other items but these are thicker. Plus the designs haven't worn off yet.

These are a very thick kind of plastic. It says nothing about being dishwasher safe or microwave safe. In general, plastic items should not be microwaved, but it doesn't say not to. I'd personally not do it.

The packaging says they are - I don't have a dishwasher, so dont know for sure how they'd do in a dw --- may need to use upper rack to reduce heat exposure to the plastic. I rinse them with dishsoap and hot water in the sink - they come clean pretty easy.

Yes, they are dishwasher safe. Mine gets very hot and the handles are fine.

I don't know if those cups are microwaveable or not, I ordered them for a friend of mine, I seriously don't know if she hand washes them or uses a dishwasher.

Although I don't see anything written on them, I would say yes, they are dishwasher safe. They are thick glass and most likely wouldn't break unless you froze it first and then put it in the hot water, or made it so a pan was hitting it inside the dishwasher. I haven't had any issues washing them in my dishwasher.

Pretty sure it is glass, really thick glass. I do not pUT them in the micmicrowave, so do not know about microwave safe. I have had these for three years now and I really like them. There is no heat transfered to the handle with a hot cup of Joe, and the loop is big enough for me to put my large fingers through without being pin1pinched against the side of the mug.

They are made of borosilicate glass - think Pyrex - and are dishwasher compatible.

Yes, they are microwave and dishwasher proof. I put mine in the bottom basket so they don't get tumbled around the dishwasher and it doesn't hurt them a bit! They are very rugged and durable.

They are dishwasher safe. They are made form the actual Jameson bottle so they are quite durable.

Yes they are dishwasher safe! However, the rubber grip will not last long in the dishwasher. I have not noticed any decrease in the insulating ability but have for the most part gone to washing mine by hand because I use mine daily and it is seldom out of my sight.

Yes, they are pretty and sturdy glass. Dishwasher friendly. About 4 -5 oz., nice size for small portion (not to over-eat!)

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

They are dishwasher safe, and not particularly fragile, although they CAN crack. Over 5+ years of use and dishwashing they will become less clear and somewhat more fragile. But I made my recent purchase because I finally found where to get new ones just like the ones that were finally worn out. I think I've had three "crops" in the last 30+ years. I've broken at least five sets of glass tumblers in the same period. Definitely good value for the money.

They are all glass but after dishwashing for awhile, the plastic coating starts to break down and crack. They are supposed to be dishwasher safe but apparently they do not withstand dishwasher heat after a period of time.
