Glass with enamel painting - I think?

I just purchased this for a whole $2 because I was curious about it. It seems to be white glass - it rings like it and I can see my finger through it. But I’m not 100% sure. It’s hand painted.

It looks like the handle was formed separate and added to the cup.

Any thoughts?

 

hard to say from your pics but looks like continental porcelain?

 

Looks like porcelain - I can see hairline fractures on the bottom.

 

Just curious (because I’m trying to learn) can’t glass get hairline cracks as well?
Thank you!

 

Looks more like a moustache cup than a coffee mug, to me..

 

Point of interest, Moustache cups were for drinking coffee from, so without the moustache attachment, wouldn't it be a coffee mug? And the orange beads may be enamel, the rest is not. It's called a 'wash'.

 

The handle screams shaving mug.

 

That's what I thought it was.

It doesn’t have the insert though?

 

Most definitely but it will not have a brownish discoloration which sometimes could indicate moisture damage. I have seen eggshell porcelain often mistaken for glass. That handle that has been applied on is definitely not glass.

 

Thank you!

 

Sorry, I meant to type "shaving mug" lol.

 

Is the paint over a raised design?

 

Most of the painting is on the surface but not really raised. The flowers are raised.
