Performance Evidence

A person demonstrating competency in this unit must satisfy all of the elements, performance criteria and foundation skills of this unit, and must manufacture two different gas-charged glass-formed illuminated signs as follows:

one sign must contain a directional symbol, such as an arrow

one sign must consist of at least three words written in script lettering and sans serif font, using three different colours.

In doing the above work, the person must:

work, shape and join the glass tubed sections safely and accurately to form the required shapes or letters

select and use relevant tools and equipment to handle and form the glass

safely attach required number of electrodes and connect glass tubing

prepare the glass and pump gas to the glass assembly safely

bombard, cool and age the glass to specifications

affix each finished sign to a panel measuring a minimum 400 mm length x 300 mm height.
