In order to finish my Technique Laboratory Management for this semester, I must attend glass blowing glass at Makmal Tiub Kaca. This class is very dangerous. We need to break the glass provided and then heat it to make a dropper and L-shaped. The product will be evaluated. The evaluation for this class is 20%. A few of my members was injured while making the product. It is quite hard to make L-shaped compared to dropper.
