| As will be seen this is a block of ebonite with three contacts arranged on the top surface. |
| Rotary furnaces can use any carbon source such as coal, coke, or ebonite as reducing agent, and they can use a variety of fuels, such as oil, coal, or gas. |
| In the presence of any of these elements, sulphur will leak and the ebonite will become dull and crumbly. |
| At last, this unit also assures the production of rubber and ebonite surface protection coverings. |
| The first synthetic material to be used in flute-making was ebonite, also known as vulcanite. |
| To use the electrophorus, the ebonite is given a negative charge by striking it with fur or flannel. |
