Dec. 15- I will start researching modern techniques that artist use today to make there stain glass.
Dec. 16- i am not having much luck trying to find information on this subject.
Dec. 17- today i have information and I have pasted them on our page.
Dec. 18- did some changes to the text on the notes that I wrote.
Jan 5- absent
Jan 21- started reaserch on new topic: blown glass
Jan 22- finished reseach and pasted notes on new page
Jan 23- edited page and fix any spelling and grammer errors
Jan 27- my team is now working on plans for interview with subject matter expert
Jan 28- interviewed the subject matter expert
Jan 29- post video obsevations:
Before the interview, I help set up the lights, and helped set the tables. I also checked the microphone to see if the audio was being captured. During the second half of the shoot, I was the camera man for the backup camera. One of the things that we should improve on is to doubble check the microphone and to see how the lights affect the video. Honestly, I thought the whole interview was interesting. For me, the only part that didnt realy exited me was the chemical equasons.
Feb. 11- Before the interview, I set the main camera up, connected the microphones up, plug in the camera,set the lights. During the interview, I mostly worked with the secondary camera. and in the end, I helped set the camera back, same with the microphones, got the cables, took the film out and set the lights down. owne thing to improve on is the lighting.

Hi Bernardo - this is Gay Wyn. I look forward to meeting you. I just worked through the page you put together for blown glass. Good job. You took some time to research the geography and history of glass.
The physical properties of glass are quite amazing. Your initial focus is on art studio glass blowing - which uses soda glass. Commercial glass blowing - like factories that make glasses, or kitchen-ware - use borosilicate glass to make their objects. The addition of boron to the silica glass formula changes the physical properties of the glass, making it much more robust to wide swings in temperature. This temperature robustness is because the boron reduces the coefficient of expansion of the glass, allowing it to experience much broader and faster swings in temperature without the associated stress of changes in size.
There is an interesting side story about glassblowing in the early days in Venice - the island of Murano. The delicate glass vessels were in high demand and the glass blowers were kept as virtual prisoners (in golden cages), thereby preventing the transfer of the Murano techniques to other parts of the world. This sort of Intellectual Property protection continues today in many technology fields. You can find more material on this on line easily.
all the best, Gay Wyn GWQuance@gmail.com
