Does anyone know if this mug is vacuum or foam insulated?

I don't believe so. It's a relatively light mug which is great for travel and it does do a good job as a heat capacitor for a good while. I've had drinks stay hot up to an hour. Depends on the environment. A great mug regardless.

I think it is some if the chemical gel used to insulate the mugs. It is filled between the inner and outer layers of the mug, and sealed at the bottom. Don't use them.

No. I would recommend Thermos 14-Ounce Insulated Travel Mug, Black, Thermos 14 Ounce Vacuum Insulated Stainless Steel Travel Mug, Stainless SteelPricey, but well worth it.

I don't know if there is supposed to be a soapy liquid inside the mug,,it is not described with one and I don't see any in the mugs that I have. I don't know what good a soapy liquid would be inside the insulated part of the mug because no water gets in there. I have washed them by hand and machine several times and there is no indication of soap anywhere If you have soap in one, I suggest you contact the manufacturer or Amazon.

I haven't dropped my mug, yet....my husband says he thinks it is stainless covered with some type of epoxy, something that is insulating. I tried scratching it....it will scratch...I used a bottle opener....but it does not look as if it will chip...hope this was helpful....I recommend this thermos cup.

Like a ceramic mug compared to a glass mug, not much difference. I own this one and a glass French press, as you know neither are insulated. If I have a second cup, I have to heat it up.

No, dishwasher detergent may scratch or otherwise damage the mug. The heat may also warp or deform the mug causing it to not be as well insulated.

Not really. This is not "double-walled" or insulated on any way. It is a great cup otherwise.

It is insulated. The bottom is nice and wide too to fit large Tupperware. Love my igloo lunch bag.

It has a little rubber around the body of the glass but I have put mine in the microwave to warm up my coffee several times and its still all good! Probably the best travel mug I've owned! Love it!

Yes, this mug is microwavable. In fact, it's one of the main reasons I bought it.

If the outside gets warm or hot with hot liquids (mine doesn't) there is no insulation, therefore no vacuum.

The cup has a stainless steel liner with the molded plastic outer shell. You won't burn your hands from the cup. For only $9.00 or so, you're not going to get a vacuum insulated cup. The lid has a sliding cover (to allow you to drink), that's what keeps the heat in if you're drinking coffee.

These double wall flasks are vacuum insulated between two layers of metal. If the vacuum is lost the insulating effect may be diminished.

There is a standard porcelain coffee mug, no insulation. It will work like any porcelain mug. I hope this answer helps you.
