Glass Bulb Bottle - An Alternative Light Source in the Philippines
Bottled water is a very common beverage in most developed nations.glass bulb bottle A bottle of water may be purchased at a supermarket or drug store in a variety of shapes and sizes. Glass is an excellent material for a variety of bottle shapes because it is available in an abundance of colors and finishes and it is very durable. It is also nonporous and will not retain odors or stains. It is easily sterilized, can be made completely airtight and does not contaminate its contents. Glass bottles are used for a wide range of purposes including beverages, household cleaning products, medical products and cosmetics, chemicals and pharmaceuticals, food packaging, and even glass art pieces.
Throughout the ages glass has been a very versatile material.glass bulb bottle In fact, its versatility is perhaps one of the reasons that it has been so widely used. For example, glass is used in windows and bottles, containers, tubing, lamp bulbs, mirrors, bells and glazes on pottery. It is also a very common and affordable material for producing solar power devices.
The most important use for glass, though, is probably its ability to withstand extreme heat and pressure. This characteristic is why it is so often used in the manufacture of glass containers for storing liquids and gases. It is why glass pipe is so often used in industrial settings to transport corrosive chemical products and for supplying drinking water. It is why a glass bulb bottle can be used as an alternative light source in the Philippines.
This page provides a very loosely organized collection of information to introduce the user to various glass/bottle making techniques and equipment. The intent is to allow the user to quickly orient himself/herself on the vast amount of information contained within the Historical Bottle Website without having to scroll through numerous pages and links. Additional specific glassmaking related info may be found checking the major headings on the Website Map page and in many of the individual bottle/glassmaker specific pages (e.g., Bottle Bases and Finishes).
For a brief overview of the history of mouth-blown glass production see the following short film clip.
A pontil scar, or "punte" ("punty") is the variable size and type of scar left on the base of a hot bottle by a pontil rod during the various steps in the mouth-blown process of forming the basic bottle shape. A pontil rod was used to hold the bottle during the final steps of the blowing process as the product was blown into its completed form. After about 1840 pontil marks became less and less common until they disappeared by the late 1860s as "snap case" tools (or similar types of non-empontilling hand-held devices) dominated the task of grasping hot bottles for finishing.
