| Lead was probably used at first for its fusibility only, but afterward it was certainly introduced for economical reasons. |
| The fusibility of clays is a characteristic which has been very imperfectly studied. |
| Iron, which is nearly infusible, acquires almost the fusibility of gold when alloyed with this precious metal. |
| Felspar is much used in the manufacture of porcelain by reason of its fusibility. |
| The offspring of these three populations were tested for fusibility against both inbred lines by colony assays. |
| Colonies grow into contact to one another within 3-6 days and are periodically evaluated for fusibility. |
