I have not heard of the maker AMora, 
SO I believe this to be a hand made item.  It is very unique and dynamic.  It appears to be a full glaze both inside and out. 
Would make an excellent display piece or as a useful tool for your morning coffee or tea. 

please see the pictures and reach out with any questions you may have. 

Cup:  2 3/4" tall  and  3 3/8" diameter
saucer:  5" diameter
