"Mineralogical Christmas celebration"

"Research Expedition" in the terra mineralia, Freudenstein Castle, Entry: 2 €

Why do minerals shine? It will be festively fluorescent at the last get-together of the mineralinos this year: Children between 8 and 12 years will embark on a journey into light at terra mineralia. Children will learn how the minerals get their fantastic luminous appearance, how one can utilise this effect and whether there are also other minerals in the exhibition, which fluoresce. Interested children between 8 and 12 years are warmly invited to join the mineralinos. Of course there is also a small Christmas snack included.

"The mineralinos meet in the terra mineralia to study meteorites"

"Research Expedition" in the terra mineralia, Freudenstein Castle, Entry: 2 €

The current topic of the children's programme at terra mineralia is: Meteorites, the chunks of solid matter from the cosmos. At 4 pm on Monday, 7th of November 2011, children from 8 to 12 years of age can launch themselves onto the trail of the meteorites. Next Monday, together with the mineralinos, we will discover how one recognises these stones from outer space, what kinds there are and what they are made of. Two mineralogists from the TU Bergakademie Freiberg will be there to answer the children's questions. Interested children from 8 - 12 are invited to join the mineralinos, the children's programme of the terra mineralia, that came into being two years ago.

Saturday till Monday, 1st - 3rd October 2011, all-day

"terra mineralia invites to the Cutting stones workshop"

"Research Expedition" in the terra mineralia, Freudenstein Castle, Entry: 4 €

With the Day of German Unification a long weekend is coming up. From 1st – 3rd October there will be an exhibition of the TU Bergakademie Freiberg at terra mineralia, where striped and colourful agates will be brought to shine. There will be several working stations available, where cutting agates can be learned. Under the expert guidance of Uwe Thonfeld ("Toni's House of Stones," Geyer), all the visitors will be able to cut minerals themselves and even cut their own stone findings. Cutting is a simple process in which the mineral is firmly rubbed on a glass plate with grinding paste. It requires patience and perseverance to achieve the right shine and shimmer but in the end the result is simply overwhelming. The beautiful, sunny autumn weather and mild temperatures make it possible for the cutting to take place right in the courtyard of the Freundenstein Castle. The costs for cutting are: for visitors with entry tickets to terra mineralia 2 Euro, for visitors without entry tickets to terra mineralia 4 Euro. The mineralinos, interested children between 8 and 12 years, meet on Monday, 3rd October, at 4 p.m. in terra mineralia. They can bring their own stone findings and learn how to cut. During this hour, Mr. Thonfeld will be there solely for the mineralinos. In addition to the weekend, visitors can also participate in a public guided tour “Last Minute” on Monday, 3rd October, at 11 am and 2 pm, where they will gain an overview of the terra mineralia collection. The costs are 11 Euro for adults and 7 Euro for children (incl. entry).

"New minerals in my collection"

"Research Expedition" in the terra mineralia, Freudenstein Castle, Entry: 2 €

What child doesn't collect something? Collecting or gathering things is part of our inborn behaviour, although we no longer rely on gathering for our survival. Collecting things from the natural environment is a particularly exciting hobby, since every object is different. It's not any different with stones and minerals. They occur in a variety of shapes and colours. So as not to lose track of things, it pays to arrange your minerals according to name or collection locality. After the summer break, the mineralinos will meet in the terra mineralia again, Monday, 5th of September 4 pm, to identify the finds they have made during the holidays, and to compare notes. Successful collecting can quickly become a passion!

"Mineralinos embark on a second search for mineral clues"

"Research Expedition" in the terra mineralia, Freudenstein Castle, Entry: 2 €

Anyone ever wondered why the Saxon electors were so wealthy? Why is Otto the Rich standing at the Freiberg Obermarkt? Why are so many treasures kept in Dresden’s Green Vault? Where did all the silver that was found during the Middle Ages come from? Saxony is a resource-rich land. Ore and spar, in particular, are abundant in the Erzegebirge (Ore Mountains). Children from the age of eight who are interested in minerals can learn about the minerals hidden here, and whether or not they can still be found in Freiberg during the next get-together of the mineralinos at the terra mineralia in the Freudenstein Castle on 6th of June between 4 pm and 5 pm. There will also be answers to questions about which chemical elements are in particular demand today, and where mining is still - or again - taking place in the Erzegebirge. This get-together also serves as preparation for the historical mining walk through the Brander district on Saturday, 11th of June, when participants will trace the clues of the region’s former wealth. Children, accompanied by an adult/guardian, will meet at the bus stop next to the church in Brand-Erbisdorf (bus route F from Freiberg station) at 9.30 am.

"mineralinos follow in the tracks of fluorites all the way to Asia"

"Research Expedition" in the terra mineralia, Freudenstein Castle, Entry: 2 €

On 2nd of May 2011 at 4 pm, the mineralinos at terra mineralia will embark on a journey to Asia. A large hall at the Freudenstein Castle has been dedicated to minerals from this continent. There one will find, among others, the accessible fluorite geode and the fluorite atomic model, the vastness of which is worth lingering around for a while. Fluorite, a commonly occurring mineral in Asia, is the highlight of this afternoon – because of its fascinating colour variations, large crystals and numerous crystal shapes. During the “Research Expedition” at the Science Centre we will learn about which crystal system this mineral belongs to, and if it is a hard or soft crystal. But there is so much more to discover in the Asia hall: for instance, one can admire numerous precious stones from Pakistan or Afghanistan, such as aquamarine, emerald or ruby. And on display are also beautiful precious opals from Australia. The mineralinos can also view some of the crystals that have been growing here, in front of our visitors eyes, since 2009. Girls and boys between the ages of 8 and 12 who are interested in minerals are very welcome to attend this event.

"mineralinos discover white gold"

"Research Expedition" in the terra mineralia, Freudenstein Castle, Entry: 2 €

Who has ever eaten chips, pasta or meat without salt? How did it taste? Probably not so good. But what do we actually use to season our food with? Does it matter if we use "rock salt" or "sea salt"? And how much salt is already in our food? Our body needs salt, the exact name of which is sodium chloride. However, too much salt is also bad for us. The mineralinos will explore the theme of "white gold" - as salt is also known - at their next meeting at the terra mineralia on Monday, 4th of April 4 pm. The mineralinos will learn a lot about salt here; the formation of salt deposits, the most important salt minerals, their occurrence and use. Salt crystals are not only beautiful, in the past they were so valuable they were used for bartering: Salt was a very popular trading currency. Today it is used in the chemicals industry and in winter it is used - however reluctantly - on our roads and walkways.

"mineralinos embark on a name search"

"Research Expedition" in the terra mineralia, Freudenstein Castle, Entry: 2 €

"Freibergite, bloedite or goethite - where do minerals get their names from?" This is the question that the mineralinos will answer on Monday 7th of March at 4 pm at the terra mineralia in the Freudenstein castle. We know of some 4,600 minerals. Where did they get their names from and why are they called what they are called? Minerals could, for instance, be named according to their geographical origin, like freibergite from Freiberg or annabergite from Annaberg. But people can also give their names to minerals, like goethite from Johann Wolfgang von Goethe and herderite from the mining official Wolfgang von Herder. However, there really is a bloedite, so where does its name come from? Often minerals also have a colloquial name, coined hundreds of years ago by miners, in addition to their scientific name. This name often tells something about the properties of the mineral. So fluorite is colloquially called fluorspar, barite heavy spar, and calcite calcspar. The "-spar" ending tells us that these minerals can be easily split. Others, that end with "-blende" or "-shine" refer to the mineral's shine. There are also names that speak of the colour of the mineral. Which these minerals are, the mineralinos will find out on Monday.

"The mineralinos discover the wonderful world of crystals at terra mineralia"

"Research Expedition" in the terra mineralia, Freudenstein Castle, Entry: 2 €

What do salt, sugar, snow, quartz, and pyrite have in common? They form the beautiful crystals that sparkle in the sun. The mineralinos will trace these crystals on Monday, 7th of February 2011, at 4 pm at the terra mineralia in the Freudenstein Castle. The mineralinos are children between 8 and 12 years, who are interested in the exciting world of minerals. But what is a crystal actually, and why does it have such a smooth surface that reflects the sunlight and sparkles so nicely? A crystal is a very special object; its atoms are regularly arranged in a crystalline lattice that determines its outer shape. In all, there are more than a hundred basic geometric shapes: salt has got a relatively simple structure and therefore forms cubes; pyrite, however, has got a complicated structure and instead forms the so-called pentagon dodecahedrons. There are some crystals that you can recognise with the naked eye, but there are also those that are microscopically small and hide inside rocks - our young mineral explorers can discover all these crystals on Monday at terra mineralia . The mineralinos will not only be able to get to know a few of these minerals, they will even be able to create some themselves.

"mineralinos discover the world"

"Research Expedition" in the terra mineralia, Freudenstein Castle, Entry: 2 €

The first meeting of the mineralinos in the new year will take place on 3rd of January 2011 at 4 pm. Girls and boys between 8 and 12, who are interested in mineralogy are very welcome. On this day, the meeting will be about the composition of our planet and rock formation. As part of the journey of discovery, the mineralinos will visit the terra mineralia because the exhibits on show here give an overview of the most important types of rock. At the same time, we explore seemingly unusual phenomena – like why do granite and gneiss consist of the same minerals? Why does one find fossilised shells in the Alps? Where there once active volcanoes in Saxony? Why does one find flints in the Tharandter Forest? Please note: From 2011, mineralinos will meet on the first Monday of every month, to learn more about minerals, our planet and rock formations. The complete programme for the year can be found on this homepage. Among the exciting topics are: "White Gold" and "Crystals – the shapes of the minerals" and there will also be another excursion. This time there will be a trip to the Brander region for the topic of "Mining in the Erz Mountains".
