NOTICE - Cinder Variations

Please note, volcanic cinder is a material mined straight from the earth. Therefore, variations in color are to be expected. Red cinder may appear a dark rust color one month, and a light, almost orange the next, and anything in between. The 3/4 Red and the cinder mixes will contain more or less black cinder at any given point.

Additionally, the sizes given are estimates. You may have pieces larger than 3/4" to 2" or 2" to 4" in the mix. If you are scheduling a delivery, it is best that you see the material in person prior to your delivery date so that you know what you are ordering.

3/4" Red Cinder

Red cinder is generally used as decorative ground cover for landscaping. The color, or shade, of the red cinder changes constantly due to the naturally occurring layers of cinder at the quarry. They may vary in color from an orange copper to a deep maroon. This picture shows the color of cinder we currently have available for purchase. Please note, the 3/4 Red Cinder does contain some 3/4 Black Cinder at this time.
