The irregular line

^{The irregular line characterizes everything that is made by hand}

  ^{We see this clearly in nature; the hand work of Almighty God}

  ^{in the lively high lines of the trees.. the strong hollows and} 

  ^{curves of the rocks, the zigzags of the mountains}

  ^{the spontaneous fury of the ocean waves.. even our earth is}

  ^{not a regular globe}

  ^{This irregular line with its liveliness, strength and spontaneity}

  ^{is the core secret of success for every faithful and sincere}

  ^{example of the visual art}

  ^{For instance, the creations of children, and the works of the}

  ^{people from primitive areas, are the spontaneous works that}

  ^{vibrate with life, and remain youthful for ever. Thus artists}

  ^{consider such works a rich inspiring base for their creations}

  ^{And our handmade designs in brass and leather products}

  ^{reformulate all these meanings that have been deep inside}

  ^{mankind since the early days of creation}

History of Glassblowing

http://en.wikipedia.org/wiki/Glass_blowing#History

Glassblowing is a glass forming technique which was invented by the Phoenicians at approximately 50 BC somewhere along the Syro-Palestinian coast. The earliest evidence of glassblowing comes from a  collection of waste from a glass workshop, including fragments of glass tubes, glass rods and tiny blown bottles, which was dumped in a mikvah, a ritual bath in the Jewish Quarter of Old City of Jerusalem

     .dated from 37 to 4 BC 

The invention of glassblowing was coincided with the establishment of the Roman Empire in the first

. century BC which served to provide motivation to its spread and dominance

On the eastern borders of the Empire, the first glass workshops were set up by the Phoenicians in the birthplace of glassblowing in contemporary Lebanon, Israel, and Palestine, as well as in the neighbouring province of Cyprus. Meanwhile, the glassblowing technique reached Egypt and was

described in a fragmentary poem printed on the papyrus which was dated to third century AD

On the other hand, the Phoenician glassworkers exploited their glassblowing techniques and set up their workshops in the western territories of the Roman Empire first in Italy by the middle of the first century AD Rome, the heartland of the Empire, soon became a major glassblowing centre and more glassblowing workshops were subsequently established in other provinces of Italy



How to change the natural color of glass?
