On our trip, we stopped in Cambridge OH at a small glass making company called Mosser. Mosser company makes pressed glass in stead of the hand blown glass that we were able to make at Blenko Glass This means that the glass is formed by molds that the molten glass is placed in.
Once the big glob of molten glass is placed on the mold, there is usually a two piece mold. In the video below, you will see how the molten glass is placed in a mold, then pressed (the mold had two sides and the molten glass is sandwiched in between then two). It is then placed under another flame to get rid of the stiff rigid marks left behind by the molds. The tip of the pitcher is then heated up again for the finisher to start the spout on it. Once the finisher completes the pour spout, the item is then examined and placed under another flame if necessary. If the pitcher passes inspection here, it is then placed on a conveyor in an annealing oven (slow cooling) to get the perfect Temperature and 4 hours later, your glass product has cooled ell enough.
Enjoy the video and pay attention to the process and how pressed glass is made compared to how Blenko blows their glass

Great job in comparing pressed glass to blown glass.
ReplyDeleteI like your comparisons between Blenko and Mosser but why not have the students do an assignment comparing the two including advantages and disadvantages of each for a specific product?
ReplyDeleteYou can turn this into a very good lesson.
Good idea about comparing Mosser's process to Blenko
ReplyDeleteI wonder if we could come up with some sort of class simulation of each process that would allow students to talk about the different in time, consistency, and production skills. Great post!
ReplyDelete"...glob of molten glass". I can hear you say these words in your voice. And how long has it been since I have heard your voice? I won't say! Looks like y'all are having a great time learning about the glass-making process(es). Very interesting!
