Glassblowing

Boy, its been long since I posted here!! But finally, I am.

This time I bring the photographs of glassblowing. This particular set of photos were taken in Jamshedpur, aka Tatanagar, India, where I have inhabited for quite some time now.

Although this series of photographs was meant specifically for technical studies, I could however, sneak in a few pictures like these, that had little technical value, but turned out to be really nice photographs.

The flame, by the way, is the Oxy-acetylene flame, that is usually used for welding/cutting all sorts of iron, steel and other metals. Fuel used was the LPG (butane/propane).

The flame, if you observe in the following pictures, is rare blue on the outside, while a dense blue "beak" in enclosed within the rare one at the mouth of the burner/nozzle. This "beak" is what I was trying to capture, but the flame was simply too bright for the normal white balance to capture. I tried quite a few tricks before realizing this. When I realized that pictures were not turning out to be as dark as I wanted, even on metering the focus at the brightest point in the frame, it 'click'ed me that white balance needed to be changed. So I switched to less whiter balance, and voila! There it was. The "beak" of denser blue flame.


Although the flame is used to cut/weld metals, here, however, the purpose is to melt the quartz (SiO2) and shape it, so as to form a capsule enclosing the specimen required, which is then, evacuated and sealed.

That's it. Enough with my technical blabber for now. Please enjoy the photographs.
