Dear Jason,
I am not a glass maker, I have zero experience on that, I am just going by logic.
Nevertheless I think that what you said is impossible, and not for a single reason.
First, if you join two pieces by fusing you will have some deformation in the shape prior to reach the needed temperature.
Second, take for example the waves piece that form the base of the bottle in question. How do you handle that? It is extremely hot, and prone to collapsing/warping.
In any case, the process is not influenced by the accuracy of Kiln’s temperature control. If you look at videos of blown glass making, the controller of the temperature is the worker. It is according to his experience and skill that he judges how much introduce the holding bar in the kiln and for how long.
Kind regards
Giovanni
