Before opening the plaster cast i was rather sceptical in what would come out and how well it might of worked. This would be the only trial i could produce in bronze as the next pour would be the final one before hand in. Realising the bronze was a more difficult process than when i was removing the bronze from the ginkgo leaves. The bronze this time was a lot more delicate and the plaster really clung on to the hard to reach places of the cast. It was a rather long process to remove all the plaster and in the end it was easier to use the sand blaster. The sand blaster also helped to remove any discolouring which highlighted any parts of the piece that need work doing to them.
Removing all the feeders proved difficult as it was hard to clamp this delicate object while having to use force to cut the feeders off. Using a sander and rotating file pen i cleaned up the leaves from any bits of bronze that weren't supposed to be there, these where all caused by the wax being too thick or leaving drip marks that effected the aesthetics. This proved to be extremely tricky as navigating the file pen without filing incorrect areas proved challenging. The pen would often catch and run across areas that i didn't want filing. It took a lot of practise to be able to control the pen and create a natural flow between the naturally cast bronze and where the worked at bronze met.
The overall form of the vines is how i envisaged yet i feel as though i may have over worked the bronze. In the early stages of casting i think that i applied the wax too thick in parts so that it was dripping down the stalk which meant i had to work back a lot of the bronze to erase the wax, this has evidently resulted in the bronze looking over worked and less organic. However this is only a trailed and has helped how i will approach the final attempt at the castings.
The time frame i have to produce the wax for the final pour is rather short, now i know the process of how to remove all the unwanted bronze am going to move on to the final piece rather than working on these piece. Before moving on i tested the finishing touches on one of the leaves to see how well the sulphur wash and polish would bring out the veins in the leaves. The aesthetic of this is perfect to how i wanted creating a high contrast between the evolved bronze (veins) and darkening the surrounding area really elevating the sculpture.

Bronze still in plaster |
|
The veins are only slightly visible at this stage |
|
Removal of the feeders to the leaves making it easier to clean and work on |
|
Removal of feeders still has plaster dust on |
|
Underneath the leaves where the feeders were attached - shows where i worked at the metal trying to blend it with the cast metal |
|
Not all the leaves fully developed however i actually like this aesthetic as not all leaves are perfect and reminds me of bugs eating away at the leaves |
|
The leaves after being sand blasted - removal of the discoloured metal this indicated that the bronze has been over worked |
|
Sulphur wash and polish added to the leaves to highlight the veins |
