Sea glass and beach cup are similar but come from two different types of water. "Sea glass" is a glass that is physically and chemically found on the beach along the salt water body. This weathering process produces natural opaque glass. "Genuine ocean glass" can be collected as a hobby and used for decoration, most often in jewelry. "Beach glass" comes from fresh water and in many cases has a different pH balance and a less opaque appearance than a sea glass. Sea glass takes 30 to 40 years, and sometimes up to 100 years, to obtain a distinctive texture and shape. Sometimes also colloquially referred to as "Drift glass" of the longshore drift process that forms a smooth edge. In practice, the two terms are used interchangeably.

Formation
The glass of the sea begins as a normal broken glass fragment which is then continuously rolled over and crushed until the sharp edges are smoothed and rounded. In this process, the glass loses its slippery surface but gets a blurry look for years.
The naturally produced glass ("native glass") is derived from pieces of glass from broken, broken, or even shipwreck bottles, which are rolled over and fell into the sea for years until all the edges are rounded, and the glass layer has been used for blurry appearance.
The artificially produced ocean glass (sometimes called "beach glass"), though superficially similar to the sea glass, has a distinctly different view. Since it does not really come from the sea, most connoisseurs will not consider the artificial "sea" glass to actually be a native glass of glass, but only falling glass, where pieces of modern glass are thrown into a stone glass or dipped in acid to produce the desired end result. Artificial-produced, glass is much cheaper and used to make jewelry, but is often passed off as real sea glass.
Maps Sea glass
Location
Sea glass can be found all over the world, but the northeast coast of the United States, Bermuda, Fort Bragg, California, Benicia, California, North Carolina, Scotland, Isle of Man, northeast and northwest England, Mexico, Hawaii, Dominican Republic, Puerto Riko, Nova Scotia, Australia, Italy and southern Spain are renowned for their gifts of marine glass, bottles, bottle lips and stoppers, art glass, marbles, and pottery shards. The best time to see is during high tide (especially tides and proxigans) and during the first tidal period after a storm.
Glass from inland waters like Chesapeake Bay and the Great Lakes is known as coastal glass. It is similar to the sea glass, but in the absence of accuracy of sea waves and salt, the content is usually less weathered. The coastal glass from the interior often has a striking design or letter on it, which can make its origins less challenging. The outer surface of the coastal glass shards can also vary textually, with one side cool and the other shiny. This is most likely because they are fragments of larger glass objects that themselves are still embedded in mud, mud or clay, slowly being hit by wave action and erosion.
Color
The color of the sea glass is determined by the original source. Most glasses of the sea come from bottles, but can also come from jars, plates, windows, windshields, ceramics or marine pottery.
The most common colors of marine glass are kelly green, brown, white, and clear. These colors are mainly derived from glass bottles that are mostly used by companies that sell beer, juices, soft drinks, and other beverages. Clear or white glass comes from clear plates and glass, windshields, windows, and various other sources.
Less common colors include jade, amber (from bottles for whiskey, medicine, spirits, and early bleach bottles), golden amber or amberine (mostly used for spirit bottles), lime green (from soda bottles during 1960) green forest, and ice or soft blue (from soda bottles, medicine bottles, ink bottles and fruit jars from the late 19th and early 20th century, windows and windshields). These colors are found around once for every 25 to 100 pieces of sea glass found.
Unusual sea glass colors include the green type, which mainly originated from the early to mid 1900s bottles of Coca-Cola, Dr. Pepper, and RC Cola as well as beer bottles. Soft green colors can come from bottles used for ink, fruit, and baking soda. These colors are found once in every 50 to 100 pieces.
Purple sea glass is very uncommon, such as citron, opaque white (from milk bottle), cobalt and cornflower blue (from Milk of Magnesia bottle, poison bottle, artwork, Bromo-Seltzer and Vicks VapoRub container), and aqua (from Mason Ball Stoples and glass bottles of the 19th century). These colors are found once for every 200 to 1,000 fruits found.
Very rare colors include gray, pink (often from the Great Depression era plate), teal (often from the bottle of Mateus wine), black (older, dark green olive glass), yellow (often from Vaseline containers 1930 -an), turquoise (from tableware tableware) and glass art), red (often from old Schlitz bottles, car tail lights, dinnerware, or nautical lights, found once in every 5,000 pieces), and orange (most marine glass types not common, found once in about 10,000 pieces). piece). These colors are found once for every 1,000 to 10,000 pieces collected. Several pieces of black glass were old enough, coming from gin, beer, and a thick bottle of eighteenth-century wine.
Antique black glass
Old black glass that has iron slag is added during production to increase strength and opacity is often damaged during shipment. These damaged vials are dumped on the dock by the beach when landing. They initially contain things like wine, gin, whiskey, drugs, and fluids that suffered minor damage. The bottles that survived the long and often rough cruises were refilled after being emptied of the original contents and recycled, sometimes for decades. They are replenished with local spirits, herbal tinctures, extracts, and medicines.
When the glass craft gets knowledge, the bottle becomes thinner. Improved quality in glass formulations and purity, as well as advances in technical improvements in glass-making techniques all aid in placing a piece of sea glass in a loosely defined era. Along with knowledge of historical trading partners visiting search locations, production sources can be deduced, but a single feature is not a reliable indicator of origin. Many similar features over a broad sample narrow the choices. Certain substances become associated with a particular color, and a bottle shape. All this helps define the country of origin. Drugs and liquor are often sold in green bottles; Green olives are the most common color for gin, but chocolate is also used as well as cobalt blue. Whiskey is contained in green and brown bottles as well. Liquor bottles for ocean freight are often square so they can use space more efficiently in shipping crates. Toxins are almost always in blue bottles. The round glass bottles, hammers, and black squat cylinders are all made, and their shape correlates with the age of the bottle with some overlap. Correlations exist today: brown beer bottles, and of course the globally recognized form of green Coca-Cola glass bottles.
In the Caribbean, many countries are trafficked, and pirates loot everything. Thus glass from many producer countries can be found with examples back to the 15th century. The old slave trade port is a good search location. Like the former colonial port in the slave-molasses-rum triangle. All former colonial locations with marine trade routes, and mother's delivery ports are major search areas.
For example, in Jamaica there is an inflow of Spanish, African, British, American, East Indian, Chinese, and Jewish (who happened to arrive around when the son of Christopher Columbus arrived to settle on the island in 1510 and much later sent with the Caribbean pirate crew) and other Europeans scattered throughout history. The majority of the black glass found on the island of Jamaica is English glass produced from the late 1600s until the 1800s in England. The ocean glass arrived in Jamaica with an old world supply chain established in the 15th century. The Spaniards regard Santiago (Jamaica) as a remote area for Cuba, and this allowed the British to liberate them from 1655 without much resistance. The first artificial glass was most likely to come with Christopher Columbus on the 2nd voyage when he claimed the island for Spain in 1494. He is reported to have landed on Dry Harbor, Discovery Bay on the north coast. Whether glass on a boat to a sea glass is part of the romance and the magic of beach combing.
Black glass is often green or brown when held to light, although it appears black to the naked eye. Weathering and oxidation, together with UV rays interacting with metal oxides and chemicals in glass and sea water are all factors that influence the color of the ocean glazing over the old exposure and time frame. In texture and color the black sea glass resembles a black sandstone stone, very much like an extrusive frozen basal rock, or obsidian black weathered, natural black volcanic glass. Gas bubbles are often trapped in old glass, dirt and irregularities in the original bottles are common and one indicator of age. Early examples are blown by hand, then a mold is used. Due to its inherent strength, you will find older pieces of dark black glass, including pieces that lasted for centuries. The potential age of black coastal glass found depends on your search location. Small pieces require trained eyes to see. Texture is a great tool to use with color. Black glass is the rarest of all sunglasses/beaches due to age and difficulty in finding it. Although when you find the old location that has long been used, can produce a large amount of material.
Collectors should be aware of the historical nature of the location, and the fact that collecting old things is considered a cultural theft in some regions of the world. In other areas, sea glass is just a piece of rubbish on the beach. Much of the historical context of sea glass is lost to the sea, but its only presence in some areas is the heritage and heritage of the location. National treasures made from trash exists, such as Glass Beach in Fort Bragg CA. Glass at Ft. Bragg comes mostly from the mid-20th century.
Hobbies
Like collecting shells, fossils, or rocks, combing shorelines for sea glass is a hobby enjoyed by many beach and beachgoers. Hobbyists often fill the decorative jars with their collections and are delighted in tracing their origins while craftsmen carve pieces of jewelery, stained glass and other decorative pieces of glass. Some collectors use their collections to create art by placing them in cement or other glue to create mosaics.
In North America, the hobby has North American Marine Glass Association, which organizes annual conferences and publishes bulletins.
Artificial
Indigenous ocean glass and beaches are becoming increasingly scarce and hard to find. More and more people are actively looking for it, and the transition to other materials such as plastics for containers has greatly reduced the amount of glass containers disposed of in the ocean.
This scarcity has caused some artisans and craftsmen to fall on worse pieces of sea glass to create what is called "double-thrown" glass, while others make artificial glass, or "craft glass", from ordinary glass pieces using tumbler stones. While such glass is thicker than most true marine glass, it has no romantic origin, and differs in many technical ways (eg, long-term exposure to water conditions creates scratched surfaces on glass that can not be artificially duplicated), this glass meet the demand for crafters at a cheaper price and in a wider range of colors.
A number of characteristics highlight the difference between artificial glass and natural sea glass, beginning with the coloration and texture of the surfaces of each section. Examples of natural sea glass will usually have a texture that is frozen and almost like flour at different points. One of the most reliable indicators for natural marine glass is the "C" shaped design throughout the exterior of the sample. If the design is located in parts, it is an authentic sea glass, because artificial beach glass usually does not have a special design. Sea glass usually comes from broken glass bottles or other household items, so the pieces you find on the beach will not be perfectly shaped, unlike artificial glass, often sold as beach glass.
