5 Essential Elements For red brand canners hbr case solution



Used groove ring wax seal finish: The most commonly used approach to make the groove ring wax seal complete on canning jars was made employing glass applied to the jar just below the blowpipe detachment position; glass which was then tooled to shape even though continue to very hot and plastic.  This process is usually identified as a "pressed laid-on ring" in canning jar terminology finish.

Thumbscrew and stopper/lid closured canning jars were not practically as common as the external screw thread/cap or simply the Lightning-form jars, but did achieve some affordable acceptance and use largely within the late 1850s to 1890s.  To quotation Dr. Julian Toulouse (1969a), "Using the thumbscrew as a tool to tighten the seal within the fruit jar was a matter of a quick flurry, and after that virtual disappearance, aside from the cumbersome Van Vliet, along with the revival like a museum jar by Whitall-Tatum.

So, what do these bits of information include as many as?  Even though the makers mark of S. G. CO. could conceivably stand for that names of a number of glass providers (most inside the jap U. S.), specified the believed age in the bottle (1920s or 1930s) and The placement on the diary user (south central Oregon) the initials Pretty much undoubtedly suggest manufacturing by the Southern Glass Business (La, CA.) which was in business from 1918 to about 1930 and was called a milk bottle producer (Toulouse 1971; Lockhart et al. 2009b).  Being aware of the maker narrows the manufacturing time down a little extra.  Nevertheless, the numbers to the rim of the end are rim day codes - a bottle monitoring technique employed by West Coast glassmakers in the mid-twenties to early 1930s - indicating that this bottle was built in February ("2") of 1925 ("five").

The quart, used groove ring wax seal canning jar pictured to the best (finish close-up beneath remaining) is embossed with SAN FRANCISCO / GLASS Performs.  This jar was also blown within a post-base mould, is pretty crude ("whittled" uneven bubbly glass), and lacks any evidence of mold air venting.  This glass corporation operated under this name from 1869 to 1876, Even though the jars from this mold had been also very likely produced as late because the early 1880s through the successor to that business - the San Francisco & Pacific Glass Works (Toulouse 1971; Creswick 1987; Hinson 1995).  1 intriguing element concerning this individual quart jar would be that the mold utilised to make it was also utilized for an earlier plus a afterwards jar - the two with various embossing, Whilst this mildew was not designed for an interchangeable embossing plate.  How did this happen?  A detailed inspection from the pictured jar reveals that there's the faint impact of the arched blank filler plate lined area just higher than the SAN FRANCISCO embossing.  The primary or original jar designed using this type of mould was embossed In this particular now protected arch with Slicing.AND.CO for that Chopping Packing Company (Zumwalt 1980).  This jar was unquestionably blown at the Pacific Glass Will work (San Francisco, CA.) who were being in organization from 1862 to 1876, instead of through the limited lived Baker & Slicing bottle manufacturing facility (also in San Francisco and precisely the same Francis Slicing since the noted packing worry and the very first glass manufacturing facility while in the American West) in business enterprise 1858-1859 (Zumwalt 1980).

The extremely significant (thirteen" tall using an approximate one.five gallon capability) hexagonal pickle bottle to your far left was a common gothic form created by various bottle makers for an extended stretch of time.  The pictured illustration is through the 1906 Illinois Glass Business catalog and is sort of equivalent in shape (and dimensions) including the shoulder design as well as the "scallop" result at The underside with the indented overall body panels.

(As a side Take note, the explained parison formation method Along with the urgent plunger typically resulted in "washboards" or "chill marks" about the higher neck of milk bottles.

Dating summary/notes: The overall diagnostic courting of cylindrical milk bottles follows the data associated with the phases of milk bottle progress found in the introduction to this milk bottle segment; click on 4 levels of milk bottle development to move to that segment.

The rest of the portion is divided to the two major condition sorts for milk bottles: cylindrical (the oldest with the milk bottle kinds) and sq./rectangular bottles.

S.  Protection of all the types is (not surprisingly) unachievable even though the subsequent features some additional photos/information regarding a couple of other variations of round pickle/preserved meals bottles to indicate several of that additional wide variety:

The Financial system jar and closure was covered by several patents issued involving 1901 and 1903 Along with the jar continuing to generally be made until eventually 1957 when Kerr Glass discontinued this line.  The lids have been made until finally 1961 indicating the final challenge with working with canning jars for courting historic sites, i.e., deposition lag (Creswick 1987).   It appears, on the other hand, that the jar was hottest in between 1903 and also the 1930s once the Kerr check this Self-Sealing Mason jar, with its cap held set up by a screw band rather than a clip, began to (and still does) dominate the fruit jar market place.

See the introduction to this "Canning Jars" segment previously mentioned for typical producing associated diagnostic courting info for canning jars.

Canning jars by using a cap (glass or metallic) and spring clip closure had been to start with patented during the late 1850s although couple if any of those before jars/closures obtained in excess of cursory attractiveness (Toulouse 1969a).  The aqua F. & J. BODINE  jar pictured to your reduced remaining athletics a Joseph Borden patented (February twelfth, 1867) metal cap and spring clip and was one of many a lot of forms that accomplished confined use over the very last four a long time on the 19th century (jar reviewed under).

Vertically ribbed:  Tall, rather slim sauce bottles with different types of vertical ribs, ridging or fluting had been a very common conformation from as early since the late 1840s or early 1850s perfectly in to the early twentieth century (Switzer 1974; Zumwalt 1980).  Mouth-blown vertically ribbed sauce bottles were being typically fabricated from aqua glass, although colorless or gentle amethyst (manganese dioxide decolorized glass) illustrations are quite common and deeper greens and blues sometimes witnessed.

Some mouth-blown bottles could have been developed as late as being the twenties or 1930s, nevertheless this hasn't been verified and is considered not likely (Lunn 1981; Rock 2001; empirical observations).
