When manufacturers produce glass, chemicals (clarifying agents) must be added to clarify the batch in order to turn it from its original color of aqua-blue or green to clear. Prior to the start of the First World War, manufacturers used Manganese Dioxide as their chemical agent of choice to clarify glass. When a jar or bottle turns purple from sunlight, manganese dioxide is the substance in the glass that reacts with sunlight to cause the color change.

You should make a list and then determine how much your jars are worth by consulting a reputable price guide. (Like the Red Book.) Once you know what you have and what it's worth, swap meets are always good places. If you have a booth or know of anyone that has a booth at an antique mall you could try that. You might even try selling them at a yard sale.

Collectors frequently refer to these numbers as "mold numbers." However, in some cases, this term oversimplifies what the numbers represented. Originally when jars were blown by hand, the number represented a specific glass blower and his team. At the end of the day the blower and his team would get paid for the amount of jars they produced as determined by the number of jars made with a given number on them. I.E.

Square jars were considered a design improvement because a homemaker could stack more jars together in less space thus allowing a family to put up more food in their small cellars or cupboards. Square Jars were made for the Smalley Fruit Jar Co. Boston, Mass in the late 1890s. Other square jars date from the 20s, 30s and later. The value of square shaped jars tends to be higher than round as it seems that fewer square jars were made.

To learn more about the value of fruit jars I recommend the Red Book of Fruit Jars #9 by Doug Leybourne. You can order the book post paid for $35 from the author by writing him at P.O. Box 5417, N. Muskegon, MI 49445. You can also purchase the book on-line at www.fruitjars.com

There have been new reproduction fruit jars from China turning up in antique malls for outrageous prices but they're worth about $6-$8 each. The regular old zinc lids don't fit right and the aluminum lids that come with them are new and shiny giving away the jar's recent manufacture. These reproductions are copies of the old Hero jars made in the 1880s. As a collector these new jars usually have a poor quality to their color and the glass has a slicker than usual feel.

The manufacture of fruit jars really didn't take off until after the civil war. Before the war, canning jars (many were actually large, heavy, bulky enamel lined cans) were expensive and difficult to use. Mason's patent was issued in 1858 but it wasn't until the Consolidated Fruit Jar Company began making jars after the war did the Mason jar really begin catching on.

Yes, jars in amber, cornflower blue, olive green, etc. are worth more because fewer of them were made and they are in great demand by collectors. The amber jars were made that way as an attempt to keep fruit from turning brown. The amber glass kept out the harmful effect of light rays on the contents of the jar. However, the jars were less popular with homemakers because the contents were more difficult to see.

Well, the Ball, Kerr or Atlas jars tend to be fairly common. However, some jars can be worth more depending on the actual embossing. (Especially dealing with Ball jars.) Jars with unusually bright colors are worth more. These were generally made at the end of a run and contain sediments and chemicals that color the glass. Amber colored jars tend to be worth more than clear or aqua jars, but this is not a hard and fast rule either.

All of the major fruit jar research books out there are out of print. There has been some discussion about reprinting Dick Roller's "Standard Fruit Jar Reference." There is also the two part Creswick book entitled "The Fruit Jar Works" and two classic books from the 1970s namely "Bottle Makers and Their Marks" by Julian Harrison Toulouse, 1971 and "A Collector's Manual, Fruit Jars" by Julian Harrison Toulouse, 1969.

Hedgehogs are small insectivores, looking much like an upside-down oval bowl, that is covered with sharp quills, which feel much like a bristly brush, with an adorable little face and ears peeking out from one end. Neither legs nor tail are very visible during normal movement. Hedgehogs roll into a ball of interlocking spines when threatened, leaving themselves all but invulnerable to any natural predator. Hedgehogs do have soft fur on their faces and bellies, and so are not entirely prickly.

This is the name for Carl McCoy's new (yet to appear) band. The rest of the original Fields are now called Rubicon and have a new singer. They are no longer considered Goth.

Cyclone does balancing by writing articles in a round robin fashion across all available spool disks. For most cases, if you have more than 3 drives, striping is not necessary for the spool objects. Striping data is used to balance traffic across all available disks.

each child reaches his or her third birthday, the family's service coordinator would assist them in learning about what resources may be available to them after the child's third birthday. Such options may include, but not be limited to the Georgia Department of Education Division for Exceptional Students which offers special education services for children ages 3-21 in Georgia.

It is very difficult to determine the age of a fruit jar without seeing it. However, there are a few ways to make an educated guess at the date of an antique jar or bottle. Probably the most important is the presence or absence of a pontil scar. The pontil scar - a ring of glass or a black and red iron-like indention on the base of a bottle or jar - indicates that a glassblower held the item on a pontil rod (when the glass was hot) while the neck and/or lip was shaped and finished by hand.

All implementations of telnetd, rlogind, and other remote login utilities generally only check the ticket expiration time at login time, and don't care about it afterwards. However, AFS will not give you access to your files anymore, even if you already have files open. Note, however, that this is just a matter of implementation. Someone could write a version of telnetd that closed your connection when your ticket expired, but I doubt that it would be very popular :-)

Inexpensive window film consists of polyester film dyed to achieve the desired color and darkness. The purple appearance is caused when the ultraviolet rays from the sun break down the dyes in poor quality film. Metalized film costs a little more but the metalized film process deposits aluminum, titanium or other metals on the polyester to replace the dyes, created on extremely stable products.
