For more info on press-and-blow equipment stop by the Glassmaking & Glassmakers web site. These machines first started use while in the mid-1890s as semi-automatic devices (requiring the hand feeding of glass) with whole automation attained during the mid to late 1910s with the addition of gob feeders.
 The following is an inventory of manufacturing based diagnostic features - such as the approximated courting ranges - that illustrate these variances and assist with canning jar dating:
So, what do these bits of information insert up to? Although the makers mark of S. G. CO. could conceivably stand with the names of various glass providers (most from the eastern U.

Horizontal complete seam: This seam was shaped the place the neck ring mold (which also contained the urgent plunger) plus the 1-section parison mould came with each other. The inner percentage of the neck ring mould - that meshed Using the higher Component of the parison mildew - was 1-piece on press-and-blow milk bottle machines as was the parison mildew itself. (The hot, partially shaped [pressed] parison could be ejected from a parison mildew with the ejection valve and moved to your blow mould by mechanical tongs. As a result, that mold didn't should be two-part.) The only real seam induced with the neck ring/parison mildew intricate was on the horizontal interface between the neck ring mildew and the top from the parison mildew, i.

 These production linked diagnostic options suggest a late mouth-blown manufacture of between about 1900 and 1915, however no info on the company itself is offered to examine that estimate towards. Click base watch to see this sort of which exhibits an embossed mildew selection (742) of no meaningful utility now. American glass makers also referred to jars formed such as this as "English pickle" bottles (Flaccus late 1890s; Illinois Glass Co. 1903).

This design and style to start with appears to have appeared to be a late mouth-blown product While device-created examples are much more usually encountered and likely first occurred all over 1905. This extensive mouth fashion is a type most conveniently tailored to The brand new semi-automated equipment which were getting to be progressively prevalent during the early 1900s (Illinois Glass Co. 1903, 1906). The footed olive seems to possess continued into at the very least the early 1930s, although seem to be unheard of following that time as other more straight, uninterrupted sided (with no shoulder constriction ridge) variations became more popular (Fairmount Glass ca. 1930; Lucas County Bottle Co. ca. 1940s). The pictured case in point is device-manufactured and it has a slight "straw" tint indicating that selenium and/or arsenic was used since the glass decolorizer.
(Be aware: Canning jars have been also normally made by push-and-blow devices in the course of the initial 50 % with the 20th century. These had been, however, diverse equipment which did make a valve/ejection mark on The bottom, but didn't ordinarily bring about the disappearing side mold seams nor the horizontal end seam found on milk bottles. This was as a consequence of The reality that each the parison and neck-ring molds ended up multi-element molds.)
Vertically ribbed: Tall, relatively slim sauce bottles with different kinds of vertical ribs, ridging or fluting were being a very common conformation from as early as the late 1840s or early 1850s very well to the early 20th century (Switzer 1974; Zumwalt 1980). Mouth-blown vertically ribbed sauce bottles were being generally made from aqua glass, while colorless or light amethyst (manganese dioxide decolorized glass) examples are reasonably common and deeper greens and blues at times noticed.
