Title: Muspratt's Chemistry 1860 article on glass and glassmaking
Post by: bOBA on May 24, 2012, 01:35:58 PM

Just a notice for a an interesting article I found from circa 1860, from Muspratt's Chemistry, a two volume set. He was then Professor of Chemistry at Liverpool University and the article has interesting engravings of glassmaking techniques of several kinds, pictures of contemporary furnace apparatus etc...

I have put it on picasa, https://picasaweb.google.com/RobertLBJ/MUSPRATTSCHEMISTRYCIRCA1860Glass

please let me know if there are any display problems etc......

thanks Robert  -  although regret the text is illegible on my screen.       If I take the magnificaiton to 300/400% it just blurs the words - although the line drawings/engravings are o.k.                      How are you seeing this on your screen??   :)

Thx Paul, on zoom it is ok on my computer but the only way I could get the words legible was to use big files, maybe the blur you have seen is loading time ......... thanks for the feedback, if others find it problematic I will take it down and try to get some technical advice, I tried smaller files and the quality was too poor to read.... so I set it up that the zoom was the way to read it........

Fine here, quite legible. I have Picasa photos software on my PC and the zoom works well on your photos Robert, it may be that Picasa and Picasa dovetail well...if you see what I mean.

Thx John,
good to hear the text is visible, a couple of folks have also let me know it is OK so I will leave it up for a bit, it may be of some interest for folks, some of the tools, recipes etc haven't changed much! thanks again,

you must make allowances for some of us older idiots  -  however, thanks to assistance from one of my sons, I've now downloaded the Picasa Photo programme - and I can now zoom on the text of Robert's pages, and all is o.k.         Also approve of some of the non glass pix on Roberts album  -  much better than looking at glass ;)
