What is EAPG pattern glass?
Early American Pattern Glass (EAPG), also known as pressed glass, was produced from roughly 1850 to 1910. Cheaper to manufacture than blown glass, this glassware was made in cast-iron molds and marketed as an economic alternative to hand-cut crystal.
How do you know if glass is pressed?
Cut glass will have sharper detail with a more defined pattern, whereas pressed glass will be smoother and worn to the touch. Look for mold marks. Cut glass will not have any mold marks and most pressed pieces do unless they are upper end pieces where someone took the time to remove them.
When was pressed glass popular?
What era is Depression glass from?
Depression glass is glassware made in the period 1929–1939, often clear or colored translucent machine-made glassware that was distributed free, or at low cost, in the United States and Canada around the time of the Great Depression.
Is pressed glass the same as Depression glass?
While pressed glass techniques of the 1920s made it easy to produce inexpensive glass, a few companies were determined to continue creating high-quality glassware. Whereas Depression glass was produced with molds (and thus are more raised in appearance), elegant glass designs were etched and have a more recessed look.
Why does glass have a seam?
No matter how snug or tight the fit between the two sections (and in some cases three) of the mold, there’s always a rough edge where they make contact–thus creating a seam. It should be remembered that glass manufactures were always interested in, and kept an eye out for, new ways to increase productivity.
Does pressed glass have seams?
Pressed glass does have seams (mold marks), but sometimes they can be hard to see and only the top and bottom small parts will show. A seam can even follow the design rather than going straight from top to bottom but that’s not at all common.
What is a Pontil in glass?
The pontil, or punty, is a solid metal rod that is usually tipped with a wad of hot glass, then applied to the base of a vessel to hold it during manufacture. It often leaves an irregular or ring-shaped scar on the base when removed. This is called the “pontil mark.”
Why is it called a Punty?
A punty is the long iron rod a glassmaker uses to gather molten glass with. Punty is short for pontil. Pontil is a French word that was derived from the Italian word puntello which can be traced back to the Latin word punto.
What does the bottom of hand-blown glass look like?
A small pinched area around the lip of a vase indicates the spot where blown glass is removed from the blowing tube. Finding a pinched area at the lip or opening of the vase is a good indicator of blown glass. Instead of a pinched area, you may find what appears to be a scar or a swirl on the bottom of the base.
