Colorado blend is a stone that comes in varying colors in light hues.  As a result, it won’t lose its color or texture.  They would work well in all scales of model railroads. Use larger particle sizes as an accent boulder in a doll house or farm landscape, or as an obstacle in a war game.  Use smaller particle sizes for a beach, gravel driveway or road.  Furthermore, use any particle size for railcar loads, in mines or quarries, or as an accent boulder in the landscape.   That makes it a natural addition to any miniature model. Therefore, Colorado Blend comes in a variety of grain (particle) sizes to meet any miniature modelers scale.  Finally, for more information or ideas, please visit our
