12 wooden crystal models, each approximately 5 cm in size.The collection includes6 cubic2 hexagonal1 tetragonal1 rhombic1 monoclinic1 triclinic modelsto clearly illustrate crystallographic structures and shapes.Delivery includes a wooden box with hinged lid.Due to technical limitations, the colors on your screen may differ slightly from the actual product.

Basic series of 9 lattice models consisting of:Copper IMagnesiumDiamondGraphite IIRock saltCesium chlorideWurtziteCalcitetriclinic translation latticeMinerals are homogeneous substances with a specific chemical composition.Their molecular or atomic building blocks are arranged in a very specific, repeating pattern. They form a three-dimensional lattice, on which both the crystal form of the mineral as well as its physical properties depend.This can be demonstrated using lattice models: In these, the atoms or molecules are represented by colored wooden spheres, and the distances by metal rods, at a linear magnification of 250 million times.The models are widely used, particularly in chemistry and physics classes.Due to technical limitations, the colors on your screen may differ from those of the actual product.Our images are for reference only; upon purchase, you will receive a product of equivalent quality.

Animal figurines from prehistoric times exert a special fascination. Their simple and almost naïve depiction creates an impression. This small, round bear statue was originally carved from amber. Our replica is made of slightly translucent, dyed plastic.Age: Neolithic; (age: approx. 3,000 years)Locality: Słupsk(Stolp), Pomerania, PolandSize: 10.5 cmReplicas, reconstructions and casts are made in-house and colored by hand. It is therefore possible that there may be color deviations between the photos and the pieces delivered.

30 fossilsin collection boxesincluding wooden caseFossils - mysterious witnesses of life. How can their hidden secrets be deciphered? On the basis of typical specimens, this collection provides a variety of answers to this question. Here you will learn everything about the process of fossilization through text and fossil specimens: From biostratonomy ( organic bodies' development from death to embedding) to fossil diagenesis (forms of embedding) to the various types of preservation. The hand specimens are numbered and have labels indicating the exact name as well as the age and place of discovery. They are supplied in system-bloc collection boxes. A detailed contents list is included with each collection.

Rock saltThree-dimensional models - very precisely constructed of wooden balls in different colors according to the elements they represent, and linked by a lattice of metal rods. They provide excellent means of illustrating the structure of the space lattice in molecules and compounds. Even in the most complicated models the atomic planes, the characteristic symmetry functions and the optical properties can easily be recognized.23 x 22 x 22 cm
