Thursday saw us leave Oglebay and head for our new home in Pittsburgh, Pennsylvania. On the way we stopped at
Mosser Glass in Cambridge, Ohio and saw a different kind of glass factory.
 |
| The morning at Oglebay provided a lot of fog which lent itself well to me capturing sun flare! |
 |
| A gather boy collects a large ball of molten glass on the end of the pipe. |
 |
| The molten glass is then cut precisely as to fill the glass mold. |
 |
| A large lever is then compressed by hand to push the glass into the mold and form the glass pitcher. |
 |
| The worker must exact the proper amount of pressure to ensure the glass fully fills the mold. |
 |
| A carry boy then takes the glass for final preparation. |
 |
| After three hours in the annealing oven the glassware is ready to be sold. |

While they only had two lines running on our visit, they have many molds they have made or acquired from other companies over their more than 30 year history.

Questions:
1. Compare and contrast the three different ways we have observed glass collected and processed in glass making (Blenko, Wismach and Mosser).
2. Are there any advantages or disadvantages you see for any of the three processes?
The three techniques all share the same principals but I really like how you're having students look at the different techniques! I think comparing them also opens the discussion for which ones are ultimately going to be the most successful as well!
ReplyDeleteGreat use of the pictures to describe the process of pressed glass.
ReplyDeleteI like that you have made a detailed series of photos of the workflow from many of the sites on the visit.
ReplyDeleteThis lesson really brings it all together in having students compare and contrast the workflow, procedures, product, etc of the glass manufacturers.
