Unmarked Candle Holder or Ikebana Vase

I recently acquired this large, studio pottery piece - find it very appealing - but am puzzled as to its origin and intended use.  The form suggests an ikebana vessel and yet something about the size and proportions argue against?  The other obvious use - as a candle holder?   I am also puzzled by the fact that, based on fairly close inspection, it is unsigned though it may well have once had a label affixed.  The surface suggests some age - perhaps dating from the 80s?  Would welcome any/all views.  By the way, it measures approximately 14" tall.  

I would plump for a candlestick. Pieces with no marks on are sooooo frustrating! Probably had a gold paper label. I would probably put it at 70's, judging from the glaze and the slightly unusual design. The 70's being the age when the Baby Boomers came of age, and there was an explosion of people trying pottery and the crafts.
If it is a candlestick, I'm not sure if it 's successful design. The unglazed interior would make it difficult to clean the wax off. Nice piece tho, unusual, elegant. Where could you buy its like in the clutter of modern mass produced rubbish?

Thanks for the informed comments - it seems the/a previous owner thought of it as a candle holder as there are traces of wax inside the two cups. Also, although the form generally suggests that of ikebana containers seems to me the proportions as well as the symetry argue against that use? In any case, thanks again for the comments (and admiration!)
