Hornfels is a metamorphic rock formed by the contact between mudstone or other clay rich rock, and a hot igneous body, and represents a heat altered equivalent of the original rock
From German which means hornstone
Fine Grained Rock, Opaque Rock
Brown, Dark Greenish - Grey, Green, Reddish Brown
Decorative Aggregates, Flooring, Homes, Interior Decoration
As Building Stone, As Facing Stone, Garden Decoration, Office Buildings, Paving Stone
for Road Aggregate, Roadstone
Cemetery Markers, Commemorative Tablets, Creating Artwork
Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Hornfels is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.

Available in Lots of Colors and Patterns, Easily splits into thin plates, Generally rough to touch, High silica content, Very fine grained rock
Siltstone is a type of sedimentary rock which is formed from fine rock particles. As the particles of eroded rock travel along with water, the edges of the rock are worn-out by water into a rounded shape.
