| Mixed with poor coal are certain unburnable materials that melt and stick together as it burns and form what are known as clinkers. |
| So-called clinkers and economized facing are especially suitable for the modernisation or renovation of existing buildings. |
| Other scoria, sometimes called volcanic cinder, resembles clinkers, or cinders from a coal furnace. |
| I was in the movie business, did some good movies, did a couple of clinkers. |
| In general, the spininess of the clinkers is inversely proportional to both the thickness of the clinker layer and of the flow itself. |
| You must refrain from dumping synthetic ropes, fishing gear, incinerator ashes, and clinkers. |
