Estimating the age of antique bottles can sometimes be a difficult task even for the experienced collector. However, by following some basic guidelines anyone can determine approximate age. Although this brief article is primarily intended for American-made bottles, glass from other countries has evolved similarly. This outline covers basic patterns but note that there are exceptions to every rule. Most bottles produced in the past years were formed by blowing molten glass into a mold. Molds were made of iron or wood and consist of 2 or 3 pieces.

Late s to s It is always fun when a ring is inscribed with a date, taking the guess work out of circa dating. Although jewelry is sometimes seen with a much later inscription than when it was actually made, that is not the norm. Rings from the early s that are not dated may also have features to help identify them. Stones in that period were often set in a close-backed mounting, and sometimes foiled as well. Stones in the rings could also be set in a silver head with a karat gold band and rose cut diamonds, all typical of this time period.
Hair and memorial rings were worn by both men and women. The crystal is a faceted octagon with a tiny layer of hair under the bottom and a dash of rose pink coloring. The diamond is set in a pinched silver collet rim and the scale design wraps around the entire ring. The diamond is 3. The color is a foil backed light brown and it has a tiny broken edge visible only under magnification.

The Copyright of Design Act initiated the use of the diamond registration mark used to confirm that a design has been registered in Britain. The diamond contained enough information to allow identification from the official records held by the Patent Office. There was a letter to represent the year so the first series ran from to Other letters identified the day and month of registration, the material and bundle number. By shifting the positions of the identifiers, a second series was started and lasted until The Patents, Designs and Trade Marks Act of rationalised the system and thereafter only a number series was used.
The system of registering designs with a specific number was introduced at the end of It superseded the previous ‘Diamond’ registrations.
A hallmark is an official mark or series of marks struck on items made of metal , mostly to certify the content of noble metals —such as platinum , gold , silver and in some nations, palladium. In a more general sense, the term hallmark can also be used to refer to any distinguishing characteristic. Historically, hallmarks were applied by a trusted party: the “guardians of the craft ” or, more recently, by an assay office. Hallmarks are a guarantee of certain purity or fineness of the metal, as determined by official metal assay testing.
Hallmarks are often confused with “trademarks” or “maker’s marks”.

We hold copies of these designs in the form of drawings, paintings, photographs and product samples, sent to the Designs Registry, part of the Board of Trade, to be registered for copyright protection between and As registration was not compulsory, there are many commercially produced designs which you will not find in our records.
For advice on modern-day registrations contact the Intellectual Property Office. Until there had been copyright protection in the UK for some textiles, but most areas of the decorative arts, such as glass, metalwork, ceramics and wallpapers, had no copyright protection at all. From , to apply for copyright protection you had to submit your design to the newly created Designs Registry, part of the Board of Trade and later to fall under the jurisdiction of the Patent Office.
Registration protected the decorative elements of the design from being copied and manufactured without permission. Today designs are registered with the Intellectual Property Office.

Look at the bottom of the page under all the marks. Click here to read more. We will start here with a 1st Period Mark or 1st Black Mark. The colour of the mark during this period was predominantly black but other colours were used, amongst them red, blue, orange, green, brown, and pink.

The latter are more usually found on Earthenware pieces.

Linda C. Sandelin Associate State Archaeologist June 11, Information on the dating of Clorox bottles may prove to be a valuable tool during the evaluation of historical sites since these items are frequently found in historic trash dumps. These bottles have distinctive markings allowing for a precise way to date the bottle; therefore one can fairly accurately date a site containing Clorox bottles. Information on dates and characteristics about Clorox Bottles was obtained for this paper from communication with The Clorox Company.
Established in Oakland, California, the Electro-Alkaline Company in began manufacturing liquid bleach for industrial purposes in 5-gallon crockery containers. The label with the diamond shaped design and word “Clorox” in the center originated at this time. Clorox bleach was used primarily in Oakland’s laundries, breweries, walnut processing sheds, and local municipal water companies.
These five-gallon containers were the company’s only form of manufacture until when, in order to save the company from foreclosure, Electro-Alkaline expanded into the individual household market by manufacturing ounce amber glass “pint” containers with rubber stoppers. This new household version quickly gained popularity and the company distributed their product throughout the country. From through the amber glass containers were used by many other companies, which bottled a variety of liquid products.
Therefore, unless the paper label is on the bottle or the stopper that has the Clorox name on it is still attached, one can not determine if it is indeed a Clorox bottle. In the company went public and became the Clorox Chemical Company. From on, “Clorox” glass bottles with rubber stoppers became distinguishable by numerous characteristics.

Over the years factory marking of pieces has evolved and although marks vary from impressed and hand written to printed emblems, the majority of bone china produced was marked in the way described below. The standard printed factory mark, included the number 51 in the centre that refers to the year when the Worcester Porcelain Company was founded by Dr John Wall.
The mark can appear in any colour, and on a variety of materials. Between and specific indications of the year of manufacture are rare but may sometimes be found in the form of the last two figures of the date, eg 75 for , printed below the standard mark. From a letter system was also used to indicate the year of manufacture.
