The Elements – Building Blocks for Minerals

In the new year, the mineralinos from terra mineralia’s kids club will again be meeting once a month to talk about mineral collecting. The first meeting takes place on Monday, 15 January at 3.30pm. This time, the boys and girls will be looking at the question of what holds minerals together deep inside.

All minerals are made up of chemical elements. Since there are around 80 different chemical elements and numerous possible bonds that feature in a mineral’s formation, there are more than 5,000 different minerals that we now know. You can picture it as a giant jigsaw puzzle. The mineralinos will encounter the most important elements and will also learn what an atom is. We’ll use different models to give them an insight into the fascinating structure of minerals. And of course, we’ll also take a look at and have fun exploring the walk-in model of crystal fluorite in the Asian Hall.

The mineralinos meet at the terra mineralia ticket office in Freudenstein Castle. For more information, please contact the Info Desk on 03731 394654 or by emailing Sessions are free of charge.

850 Years of Freiberg Silver

There’s plenty to celebrate in Freiberg in 2018! It’s 850 years since the first silver was discovered here, 700 years since the Muldenhütten smelting site was founded, and the tenth birthday of terra mineralia. It’s for this reason that the mineralinos from terra mineralia’s kids club will be talking about Freiberg silver at their meeting on Monday 5 February at 3.30pm.

According to legend, silver was first found in the Freiberg mining field in 1168 at the Schüppchenberg. A flurry of mining activity followed which, in spite of numerous interruptions, continued until as recently as 50 years ago. But silver wasn’t the only substance mined – lead, zinc, tin and copper were too. The boys and girls from the mineralinos will have fun learning what was produced from the raw materials and why they were so important. The children will learn how the deposits were formed, how they were tapped and what the many and varied consequences were of mining for the region. With all of this knowledge, there’ll be nothing more standing between us and our first mineralinos field trip in March of this year to the Freiberg Reiche Zeche.

The mineralinos meet at the terra mineralia ticket office in Freudenstein Castle. For more information, please contact the Info Desk on 03731 394654 or by emailing Sessions are free of charge.

What do you do at a Mineral Show?

At our meeting we prepare for the visit of the Freiberg Mineral Show. The mineralinos have their own stand there and are allowed to exchange their minerals with other visitors or sell them. This is going to be exciting!

What is a Micromount?

Micromounts are not tiny mountains, but a special kind of minerals which can be collected. They are small and therefore have to be viewed through a microscope or a magnifying glass. On Monday, 4 June at 3:30 pm the "mineralinos" from the children's club of the terra mineralia will learn why such small minerals are collected.

Anyone who has visited the terra mineralia exhibition will remember many of the minerals on display. They are sometimes really huge and fill entire showcases. Such objects, known as major specimen, are in the least mineral collections. But even middle size and regular size pieces are not found in every collection. The micro-minerals, known as micromounts and especially prepared for microscopic viewing are popular among many collectors. Only few know that Mrs. Erika Pohl-Ströher, the donator of the exhibits in the terra mineralia, collected also micromounts. Why she did so and why other collectors even specialize in collecting micromounts, can only be understood from looking at them under a microscope. Because there you can see the incredible beauty of these small mineral specimen that are in no way inferior to their big siblings.

It's sometimes very expensive to mount the small minerals in their boxes or cans. Numerous steps are necessary for this. The girls and boys of the mineralinos are allowed to try and learn this by themselves. They have the opportunity to prepare micromounts and are welcome to bring small mineral pieces too.

The mineralinos meet at the cash register of the terra mineralia in the Freudenstein Castle. For further information, please contact the Information Desk under 03731 394654 or at Participation is free.
