Heat reactive paints have other applications than magic cups. These paints can be used as frost indicators on roads. However, they are more suitable for indoor use because of the low resistance of their pigments to UV radiation. Thermochromic inks are used to prevent forgery. They can appear on a document when someone tries to photocopy it. They appear on some means of payment such as luncheon vouchers. On packaging, thermochromic inks can be used on beer or wine bottles to indicate the correct serving temperature: their colour changes irreversibly if the recommended storage temperature is exceeded. Production of magic ceramics The production of magic mugs requires a great deal of know-how and experience and most of the manufacturers of magic (heat reactive) ceramics are located in Asia. Most ceramic mug producers have partially automated production lines as can be seen on our Blog: https://custopolis-gifts.com/2-10-mugs/ .

You would like to offer a magic mug to a loved one and you would like to explain how it works. Here are some explanations on the action of the thermo-reactive paints that cover the magic mug. This action is similar to that of glasses that are automatically tinted (photochromic glasses). The transformation is due to the tinting activator. The silver halide molecules in the glasses release metallic silver when exposed to the sun's ultraviolet rays. This component is black and the lenses darken. When UV exposure is reduced or stopped, the silver is absorbed by the halide ions and the lenses return to their original state. UV radiation therefore changes the structure of certain molecules and affects their optical properties as well as those of the lens itself. A similar phenomenon can be observed with heat-reactive paints: a molecule used in the paint changes its shape when heated to a certain temperature. The same effect can be seen in mugs. So, thanks to this thermo-reactive coating, our magic mugs to which a boiling drink is added can make your text, your image or your photo appear. This happens very quickly. However, in order for the mug to fulfil its magical function, it must first be well made and then it is essential to take care of your magic mug, A birthday party should be celebrated with dignity with unusual gifts ideas so what could be more representative than magic mugs, the cute magic gifts ideas for a birthday.

Stamping Stamping is a technique for manufacturing and modifying objects from a flat, thin sheet of metal (a piece of metal obtained by rolling) whose shape cannot be developed from a mould (e.g. a one-piece car body). The raw material that has not yet been stamped is called Becker. Stamping is a technique widely used in the household appliances industry. Stamping is a technique of "plastic" deformation of the material: elongation or local constriction of the sheet to obtain the desired shape. Stamping is done with very powerful presses. Gifts-custopolis.com proposes metal tins with a lid that can be personalised with different decorations: Mother's Day, Secretaries' Day or professional birthdays, with an unforgettable holiday photo or with a photo of whoever you want. A white metal box personalised as a birthday gift, an unusual birthday gift idea, is already very nice, but decorated with a work of art on the lid it becomes totally unexpected, birthday gifts for a work of art enthusiast!

History of tinplate According to Wikipedia: "The invention of tinplate dates back to the 13th century and is attributed to Bohemian and Saxon metallurgists. The secret of its manufacture was long and carefully kept. At Colbert's request, this material was imported into France by German technicians. The first tinplate factory in France was founded in 1665 in Beaumont-la-Ferrière in the Nièvre. Others were established in Franche-Comté, Alsace and Normandy. However, they soon collapsed under the competition from the English and Welsh, who were masters in the art of tinplate manufacture. Tinplate production remained the prerogative of Great Britain, which supplied the entire French demand until the last years of the 19th century. "Tin was originally produced sheet by sheet, by dipping in molten tin after careful pickling. The modern process of tinning is done by electrolysis on a steel strip that runs at high speed. This tinning strip serves as the cathode, the anode is made up of pure tin bars, which supply the electrolyte with Sn2+ ions. The electrolyte consists of 4-hydroxy benzene sulphonic acid (HO-C6H4-SO3H) and various adducts. The thickness of the deposited tin depends on the aggressiveness of the intended contents (e.g. the acidity of sauerkraut is more demanding than powdered baby formula). This "sandwich" alloy of steel and tin has good hardness and guarantees high corrosion resistance. It is a non-toxic alloy, which is why it is used extensively in food packaging.

History of the cup Long ago, before we had cups or even pots, people drank from clay calabashes or jars that they made themselves by hand using the local materials available at the time. No wonder it took them so long to invent a pottery vessel that could keep a liquid hot or cold without burning up! As to who actually invented the cup, it is not entirely clear! But it was in ancient times that pottery cups were used for drinking water and other beverages in Asia and Africa, as well as in Europe and North America. The oldest cups found in different parts of the world are clay vessels that were discovered in Egypt during excavations conducted between 1933 and 1938 by the archaeologist Amelia Biliotti. They date back to 4000 BC and have certain similarities with today's ceramic cups. In ancient times, drinking vessels were mainly used to store water, not to drink it, as most modern glasses are today! The cup used to be made of wood in the countryside, and of thick earthenware in the cabarets where it was often decorated with floral motifs.

History of the cup The mug as the perfect gift for everyone The main way to personalise a mug is by writing designs and texts on it.

History of the cup Expensive beverages, tea, coffee and chocolate give rise to services that are mainly used for consumption but also dedicated to collectors' items, without it always being possible to distinguish the different uses. The size of the services also varies, and the pieces that make up the services are made using multiple techniques that fall under the heading of goldsmithing or ceramics. The earliest known example of a pottery vessel capable of keeping a liquid hot or cold is an ancient Chinese pottery jar dating from the Tang Dynasty (618-907). A scholar, Xu Xiake, mentioned the origin of porcelain in his book "Zhongguo chuantong shi" (中國出现的歷史), published in the 1730s, which describes that Emperor Muzong of the Tang Dynasty ordered the creation of high quality porcelain during the reign of Empress Wu Zetian, who was also the Emperor's wife. We have no idea how old these ceramic cups are, but they have certainly been around for a long time! They were made in China during the Tang Dynasty (618-907 AD), and by that time there were already about 20 different types of ceramic cups on the market; in addition, there were many others made by potters, all of whom used clay from different sources in the country, with varying degrees of skill and quality control!

History of the cup Tea was introduced during the Chinese Han Dynasty (206 BC - 220 AD). The more than four centuries of Han Dynasty rule are widely regarded as one of the "golden ages" of Chinese history. With the beginning of the Han Dynasty, the pottery industry developed and many types of vessels appeared on the market. The need for a container to drink tea led to the development of the cup, especially the handleless cup in China. Europe discovered tea in the 17th century with the development of trade relations between East and West, but Europeans preferred to drink their tea very hot. The handle was therefore invented in Europe by the German Johann Friedrich Bottger in 1707. In France, the ordinances of 1699 and 1709, which restricted the use of precious metals, encouraged the development of ceramics, particularly earthenware and porcelain, which played an increasingly important role in the creation of cabarets (lunch services) for serving exotic drinks. Throughout the 18th century, there were many innovations in decoration, technique and form.
