EB Glass
The long article on glass in the 11th edition of the
Encyclopaedia Britannica

This is my scan and proofreading of the long article on Glass in the 1911 Encyclopedia Britannica.
I own a copy of the onion skin 11th edition of the Encyclopaedia Britannica, this being the last edition which had very long signed articles expressing views of opinionated experts. Before this time encyclopedias were published over several years and after this time they had much shorter articles written anonymously as we now expect. It was published in 1910-11, just before WWI and updated with 3 volumes printed just after WWI. The onion skin edition makes each volume much thinner but also harder to scan. I refer to the EB much more often than one might expect because its comments on stuff that hasn't changed are still good and often it has comments on events and places of the previous 100-150 years that would be much harder to find in a modern library. Everything has to be taken with a grain of salt, considering how a British writer would look at the colonies, etc.
 [A volunteer (wiki) proofed scan of the much of 11th EB is available on the internet with the glass article at http://www.1911encyclopedia.org/Glass  without pictures.  A set of images of the pages with included figures is at http://ia311327.us.archive.org//load_djvu_applet.php (longer version in link) select page 99 in the page number drop down.]

The article on Glass, actually several articles pushed together, is very good, very complete, and especially useful as it was written just as the entire world of glass was changing with the introduction of mechanical bottle and sheet glass manufacture and the end of hand blown mass production. 2001-01-10

I have just added the article from the 1922 added volumes, considered with the 1911 Eleventh Edition to be the 12th Edition.  Instead of separate pages, the whole article is together. EB Glass 1922 2005-09-23

HOW I CLEANED THE SCAN
As mentioned, scanning an onion skin edition can add a lot of garbage. (The table on page 91 and Fig.15 on page 87 indicate the problems)  In cleaning up the files, I have used the Microsoft FrontPage spell checker. In many cases, I left the British spellings (colour) intact, but some were changed where I felt the British usage was very dated or confusing to American readers.  Some changes were made on the basis of logic (tha became the, or that, or than, depending on context) while others, especially dates, were corrected based looking in detail at the original document.  Normally, names, titles of documents and foreign words (Latin, German, French) are not proofed too closely.
