  • MA-22 SET OF 45 ROCKS PVG INTERNATIONAL’Soffers excellent collection of Rocks,Minerals and ores used as teaching aid for beginers or in advance stage of studies. Collection of 45 Rocks in Wooden Box with 45 Big Specimen Set of Rock Igneous ,Sedimentaryand Metamorphic Rock with 15 specimens as the representative of each type of rock. Igneous rocks which are formed when magma or lava cools and solidifies. gneous rocks are fire-born, meaning that they are formed from the cooling and solidification of molten (melted) rock. Sedimentary rocks are formed from the accumulation of weathered rock fragments, organic matter, or minerals in layers. These layers are then compacted and cemented together to form rock. Metamorphic rocks are formed when igneous and sedimentary rocks are subjected to high temperatures and pressures, causing them to change form. Common sedimentary rocks include sandstone, limestone, and shale. These rocks often start as sediments carried in rivers and deposited in lakes and oceans. When buried, the sediments lose water and become cemented to form rock. This is an ideal collection for the Study of Earth Stones for Geologists, educationists to teach students and for classroom use for all earth science studies. This rock collection for classrooms is the perfect educational tool to help engage students in a hands-on way. Clearly labelled and affixed to sturdy cardboard  or wooden backing with polished wooden box having front glass.

SIEVES A sieve, fine mesh strainer, or sift, is a tool used for separating wanted elements from unwanted material or for controlling the particle size distribution of a sample, using a screen such as a woven mesh or net or perforated sheet material. Sieves are used in research and development, environmental monitoring, and quality control. Specific applications include sieving soil samples in the construction industry, separating particles in chemical and pharmaceutical processes and measuring the particle size distribution in food production. The sieving process involves passing a material through a mesh or other device with an opening size of less than the material’s particle size. The particles will either pass through to the other side, be caught in the mesh, or be deflected according to the shape of the opening. PVG’S Test Sieves are of High quality ,accurate, made of brass & stainless steel material to ensure durability.Our range of sieves are in the category of laboratory and quality control test sieves.
