As the excavation season progresses, it isn't uncommon for some tools and materials to become scarce as supplies are used up. In our case, certain cleaning
tools employed by the conservators were no longer available. In a display of ingenuity, student intern, Vale
Vafaei, began experimentation with the existing supplies to make her own Dremel
polishing tools for the removal of light surface debris on copper alloy
objects. This was accomplished by
adhering polyethylene foam to used Dremel bits and cutting
them into the required shapes. The
results were both elegant and effective.
Pure titanium grade 1 provides optimum ductility and formability and high mechanical strength. It is very easy to weld and loses its alpha microstructure under heat treatment. Correctly connected elements don't lose its original physical properties. It is resistant to corrosion and environmental effects.
