Insulated bottle History "The first known bottles made of glass were created by the Egyptians around 1500 BC. The bottles were formed by placing molten glass around a core of sand and clay. The core was then hollowed out once the glass had cooled. Making the bottles was a long and complicated process, so they were considered a luxury item in ancient Egypt. Around 200 BC, glass bottles were made in China and Persia, as well as in Egypt, using a method of blowing molten glass into a mould. The Romans later adopted the same method and the technique spread throughout Europe in the 1400s and 1500s. In France 1888, the Arsonval vase An important step was taken by the physicist Arsène d'Arsonval (1851-1940), one of the greatest French scientists. He invented a revolutionary container, the d'Arsonval vase. In 1888 he introduced the first double-walled glass bottle with an internal vacuum. Although we generally use the isothermal bottle to keep our drinks hot, it was originally designed to store liquid air at very low temperatures for several days. His colleague, the physicist Violle, improved it by coating the inner surface with a thin metal layer to reduce radiation losses. Thus was born the very first isothermal bottle in France. With a height of 40 cm and a diameter of 20 cm, this hemispherical vase is made up of a highly insulating silver double wall with an internal vacuum.

Insulated bottle In the United Kingdom 1892, the Dewar vase The Scottish chemist and physicist Sir James Dewar (1842-1923) was the first to produce liquid hydrogen, which was the coldest substance ever produced. To store this cryogenic material at very low temperatures, he constructed insulated boxes from cork, hay or crumpled newspapers, but none of these solutions held the liquids sufficiently. He then discovered and improved the Arsonval vessel. In 1892, he proposed his version of the double-walled glass vacuum flask that bears his name, the Dewar flask. It takes the form of a glass balloon with a straight neck. The narrow space between the two walls is almost entirely free of air, this partial vacuum prevents heat conduction and convection for better insulation. He added silver as a metallic coating to prevent radiation. This invention eliminates any possibility of heat transfer by conduction, convection or radiation. He hired a professional glass blower to make a stronger balloon. In 1898, he used this container to transport and introduce liquid hydrogen to the world.

A birth day is a very important celebration for all of us. On this day we are the heroes of the day. Originally (and still in some families and peoples), the birthday boy or girl gave presents to his or her parents (especially to the mother) to thank them for giving birth to him or her. Since the Middle Ages, it was the birthday person who organised the festive meal, so each guest brought a share of the meal. Later on, as not everyone worked in the catering industry, everyone brought the birthday boy or girl something from their own production. Today, giving a birthday present has become a custom and an occasion to show affection to a relative, friend or colleague. But what gift should you give to a friend, grandmother or colleague? We suggest a nice little gift: a personalised mug with a personal photo or a message of your own invention. For example: For the best granny in the world. To my lifelong friend. To the funniest colleague, "It's the crisis, everything is increasing, even your age", "50 years old = 30 years + 20 years of experience" or any other message... It's up to you to choose or to find the message that best suits the person concerned. The originality of the mug is its decoration inside, a special colourful and nice birthday decoration.
