Your Highness . . . As a glass blower/lamp worker myself (AND ALSO NEW TO THESE PAGES - please break me in gently!) I must say that this is not an accomplished item, but still beautiful just the same. I can say this, for "us glass-workers" always tend to attribute makers skill to that of the foot or the base of an item, of which is the arguably the most difficult in terms of technical abillity and skill to make in glass. It can take FIVE YEARS or more to spin oput a round foot for a drinking glass (for example) of more than 2" diam! And a spun foot still remains the most desirable of stands for such glass. One sees many of such items with bases of wood and or onyx and the likes, due to the fact that most lamp workers have a very limited "flame-size" at their disposal. Particularly when using soda-lime glass (as your item has been produced from). Gas & air, melts soda lime glass and a simple Bunsen Burner can achieve remarkable results, however the flame size is limited, hence the reduced sizes of the bases/stands and feet of these pieces. 9 out of ten, will crack after cooling! They are also quite literally "annealed" whilst being made at the lamp, where as Borosillicate glass can stand higher degrees of melting temperature and is less volatile during annealing. At best needing NONE!
Borosillicate glass on the other hand will take much more working time allowance. Gas and oxygen is needed to melt this glass and the lamp burners are equipped with rotating flame sized jets. From say a needle sized flame to one as large as ten inches wide or more! This enables one to spin out a foot and to afford a larger, stronger base to such items as like your item as shown. This glass also requires no annealing time and TIME equals money! The down side of such glass is that colours are very limited and insiped - even today. I have spent some TWENTY YEARS OR MORE developing colourant recipes which are compatable to Borosillicate and trust me, its been difficult.
Anyway, whoever it was that produced your Lady, is technically accomplished and what I say above should not detract, however, as with any so-called artist (no matter how accomplished) one is only as good as ones "ideas". I wouldn't mind BETTING that your gymnast is from one of a series that "The Lamp Worker" is proud of, will continue to be, and will develop ever further. Your lady IS modern, but thank the lords that new glass makers are ensuring that "GLASS ARTISTRY" is not a dieing trade! Jazz.
