These became coated with layers of lime mud, and formed small balls (less than 0.5 mm diameter). Over time, countless billions of these balls, known as "ooids" or "ooliths", became partly cemented together by more calcite, to form the oolitic limestone we call Portland limestone.

fossils in limestone mud. C. Two relatively rare limestone varieties are: 1. Coquina-very coarse, recognizable shells, much open pore space. 2. Chalk-very fine-grained, white or tan, soft and powdery. B. Oolitic limestone-grains are small spheres (less than 2 mm in diameter), all about the same size.

These limestone spheres, which come in three sizes, are painstakingly carved by hammer and chisel, using a caliper repeatedly to assure its rounded nature. These are made in a mountain village where the stone benches exist and where the inhabitants of the village have been carving stone for the last 300 years. They come in three sizes. 9" Diameter 12" Diameter 15" Diameter

Glass balls are an important part of our program. Beginning with a size of 1 mm, we produce balls in many different designs. You will find further information about our small balls (borosilicate balls) here.From 20 mm up to 150 mm diameter, these balls are available in various colors and designs.

The three most popular diameters for the master calibration spheres for smaller diameter probes are 4 mm ( 0.157 inch ), 6 mm (0.236 inch ) and 10 mm ( 0.3937 inch ). The smaller diameter master spheres are used to calibrate the smallest probe spheres and so on with the larger diameters.
