Glass/Porcelain in Carry-ons

I'm moving over with only what fits in my allotted luggage. I'm considering putting a few fragile things in my carry-on including my degree certificates in frames, a few other framed pictures, four porcelain coffee mugs and a glass lantern my mom gave me to ensure their safety.

My question is.... is glass like that allowed in a carry-on?

Yes.  I have carried things over both ways.  It's fine.

I think I had some things like this in my carry on a year ago, on Continental.

To be on the safe side, I would call your airline and ask someone directly, just so that you don't get any surprises at the airport and have to dump something beloved.

My mom brought me over a glass cake stand a few years ago, she packed it in a box and used small bags of snacks for cushioning, goldfish and things like that. And I got to eat the packaging!!

I would recommend allowing for some "breathing room".  I managed to get a dozen plates, platters, and assorted frames over here by not over-packing my suitcases.  My mom (the QUEEN of "what? I might NEED that black terry overcoat if my three other coats don't work!") managed to snap one platter in half simply by over-packing.  I think it probably broke when she zipped up the bag. 

Otherwise, yeah, no troubles for me. And my mom had at least wrapped it in plastic, so no real troubles for her either.

I would just wrap things really well in bubble wrap, clothing, whatever to keep it from jostling around in the overhead compartment.

Has the lantern ever been used with flammable liquid in it?  Tim's friends have run into problems trying to take their steam engines (16mm gauge) on airplanes because even though they are empty, they once HAD butane in them and therefor could be flammable.  But everything else should be okay!
