Does this have a seam down the middle of the cup opposite the handle?
Can you heat this in the microwave?
Hello, according to the manufacturer this mug has a very light seam. It is microwave safe, as well as dishwasher safe. Thank you!

Is this made from borosilicate glass (aka Pyrex type glass) which does not get hot?....either from the liquid(coffee/tea) itself or from being placed in the microwave ?
If not, do you have any other product lines that use borosilicate glass to make bowls, plates and/or cups?
Hello, This item is not made from borosilicate glass. I have located and confirmed the following items to have been made from borosilicate glass: Item 6017298, 6002480, 580770, 6017021. I hope these are of use to you. Thank you!
