Don’t worry — your e-mail address is totally secure. I promise to use it only to send you Clock Collecting Tips. There are so many styles and types of clocks, made by so many clock makers and from so many countries, that I was totally lost. Over many years, I have learned a lot. I have concentrated on the American clock companies for my collection, so there is much for me to learn about clocks from outside the US. The question I get most from the comment form on this web site is:

Are they somthing else? Thanks Discount Fiestaware – 26th Nov, 09 There is old and new Fiesta that have no stamp at all, such as the gusto bowls. It can be tough to date Fiesta with no markings — it all ces down to identifying the color and determining if that particular piece was produced by HLC. Tell us more about your Fiesta Karlie – 27th Nov, 09 That was very informative, and know i am looking in my cupboards to see how old my new fiesta is Jane Schenck – 2nd Jan, 10 The newer ones have the ink stamp.

But one piece, a covered butter dish only has a rather crude Fiesta molded into the bottom, the E in fiesta looks like uppercase, but only the E, and in another area at the side of the bottom of the dish is a small white C. It is in a rose color. I read somewhere about fake butter dishes. My gut says this is a fake but then I wonder if it is rare? I have 64 pieces and this is the only one that looks strange.

Similar to how explaining a joke ceases to make it funny, overkill in your dating profile can suck the intrigue out or a first encounter. Too much information can come off as overbearing, leave you with a conversation void on a first date, or simply take up way too much of your time and energy.

Terrestrial planets have hard surfaces that can be re-shaped by several different processes: Impact Cratering There are still small chunks of rock orbiting the Sun left over from the formation of the solar system.

Some of them have orbits that cross the orbits of the planets and moons. When they get close enough to a planet or moon, they will be pulled in by the large body’s gravity and strike the surface at a speed of at least the escape velocity of the planet or moon, i. At such speeds, the projecticle explodes on impact and carves out a round bowl-shaped depression on the surface. This process is impact cratering.

How can you distinguish an impact crater from a volcanic crater? Volcano craters are above the surrounding area on mountaintops while the craters from impacts are below the surrounding area with raised rims.

Some bike parts have a date code cast or stamped into the piece. This clearly is when the component was made and not when the bike was made, but unless the component or bike manufacturer had lots of stock lying around in inventory, the date should be a fairly good indication of the year of the bike. At least it would be the earliest date that the bike could have been made.

The history of this foundry is well documented [1,2,3]. The first foundry was commercially more successful, while the second one was using a more advanced technology of galvanic silver deposition, which was first applied in Esslingen by the German chemist Carl Haegele in , the brother-in-law of Alfred Ritter. In the same year the Esslingen factory was dismantled and its equipment was incorporated into the Geislingen foundry. During the next thirty years WMF experienced a period of rapid expansion, which lasted until the beginning of the World War in This WMF branch was mostly importing the base-metal items from Geislingen, performing silver-plating and then selling them in Russia under their own marks, see my recent article in ASCAS Newsletter [4].

Your Message Properties Aluminum diamond plate has been specially formulated and manufactured to create an attractive, yet robust material suitable for a wide variety of applications. The raised diamond pattern on the sheets is formed by hot-rolling the aluminum. Embossed recessed diamond sheets are also available. Diamond plates can be polished to a highly reflective finish for applications that require a beautiful surface as well as a tough exterior.

The sheets are made from Aluminum , which consists of aluminum alloyed with 1. This provides superior strength over pure aluminum, creating a more durable product that can still be cut and shaped effectively. The metal is strain-hardened and partially annealed a form of treatment the improves malleability.

A phenotypic characteristic, acquired during growth and development, that is not genetically based and therefore cannot be passed on to the next generation for example, the large muscles of a weightlifter. Any heritable characteristic of an organism that improves its ability to survive and reproduce in its environment. Also used to describe the process of genetic change within a population, as influenced by natural selection.

A graph of the average fitness of a population in relation to the frequencies of genotypes in it. Peaks on the landscape correspond to genotypic frequencies at which the average fitness is high, valleys to genotypic frequencies at which the average fitness is low. Also called a fitness surface.

The question I get most from the comment form on this web site is: “What can you tell me about this clock?” Most people do not collect antique clocks per se, but end up with one or two clocks that were handed down from family members.

Each of the pictured bottles has a relatively short description and explanation including estimated dates or date ranges for that type bottle and links to other view pictures of the bottle. Additional links to images of similar bottles are also frequently included. The array of references used to support the conclusions and estimates found here – including the listed dating ranges – are noted.

Additional information and estimates are based on the empirical observations of the author over 50 years of experience; this is often but not always noted. Various terminology is used in the descriptions that may be unfamiliar if you have not studied other pages on this site. If a term is unfamiliar, first check the Bottle Glossary page for an explanation or definition. As an alternative, one can do a search of this website.

Figured Flasks Figured flasks is a generic name for the large class of liquor flasks primarily produced between and Due to their esthetic and decorative nature, these flasks were infrequently discarded unless broken so many survived to the present day.

We all have old family photos. These may be loose or in albums or they may be in the form of postcards or even fragile black and grey glass negatives. So what about dating? Photography started in but at that time was really in the hands of a few scientists, professionals or wealthy amateurs. Not many family photographs exist from that era unless they are beautiful images on a polished silver plate that looks like a mirror. These are daguerreotypes as invented by Daguerre in France.

Whatever happens, it is always for the best! With time I had realized that on ebay auctions there is a great number of silver-plated WMF items with marks similar to those on my Hungarian tea glass holders, that means containing the three-letter inscription “WMF”, with or without dots, and in some cases the letters “M” and “F” were joined together.

General considerations Distinctions between relative-age and absolute-age measurements Local relationships on a single outcrop or archaeological site can often be interpreted to deduce the sequence in which the materials were assembled. This then can be used to deduce the sequence of events and processes that took place or the history of that brief period of time as recorded in the rocks or soil. For example, the presence of recycled bricks at an archaeological site indicates the sequence in which the structures were built.

Similarly, in geology, if distinctive granitic pebbles can be found in the sediment beside a similar granitic body, it can be inferred that the granite, after cooling, had been uplifted and eroded and therefore was not injected into the adjacent rock sequence. Although with clever detective work many complex time sequences or relative ages can be deduced, the ability to show that objects at two separated sites were formed at the same time requires additional information.

A coin, vessel, or other common artifact could link two archaeological sites, but the possibility of recycling would have to be considered. It should be emphasized that linking sites together is essential if the nature of an ancient society is to be understood, as the information at a single location may be relatively insignificant by itself.

Similarly, in geologic studies, vast quantities of information from widely spaced outcrops have to be integrated. Some method of correlating rock units must be found. In the ideal case, the geologist will discover a single rock unit with a unique collection of easily observed attributes called a marker horizon that can be found at widely spaced localities. Any feature, including colour variations, textures, fossil content, mineralogy , or any unusual combinations of these can be used.

It is only by correlations that the conditions on different parts of Earth at any particular stage in its history can be deduced. In addition, because sediment deposition is not continuous and much rock material has been removed by erosion , the fossil record from many localities has to be integrated before a complete picture of the evolution of life on Earth can be assembled.

Using this established record, geologists have been able to piece together events over the past million years, or about one-eighth of Earth history, during which time useful fossils have been abundant.

The division is based on differences in mechanical properties and in the method for the transfer of heat. The lithosphere is cooler and more rigid, while the asthenosphere is hotter and flows more easily. In terms of heat transfer, the lithosphere loses heat by conduction , whereas the asthenosphere also transfers heat by convection and has a nearly adiabatic temperature gradient. This division should not be confused with the chemical subdivision of these same layers into the mantle comprising both the asthenosphere and the mantle portion of the lithosphere and the crust: The key principle of plate tectonics is that the lithosphere exists as separate and distinct tectonic plates , which ride on the fluid-like visco-elastic solid asthenosphere.

Jack of plate, English or Scottish, c Jack of plate, English, c Making a Jack of Plate A jack[ dubious — discuss ] or jack of plate is a type of armour made up of small iron plates sewn between layers of felt and canvas. They were commonly referred to simply as a “jack” although this could also refer to any outer garment. This type of armour was used by common Medieval European soldiers and the rebel peasants known as Jacquerie. The main difference is in the method of construction: Jacks of plate were created by stitching small overlapping squares of iron in between two canvases.

The garments weighed about 17 pounds, which made them much more pleasing to wear than solid breastplates. They allowed soldiers with weapons to rest the butts of the weapons firmly against their shoulders, which wasn’t feasible with smooth surface plate armours. The present day equivalent of a jack of plate is a bullet-proof vest. Although they were obsolete by the time of the English Civil War many were taken to the New World by the Pilgrim Fathers as they provided excellent protection from Native American arrows ; one dating back to was recently found at Jamestown.
