| Colonies grow into contact to one another within 3-6 days and are periodically evaluated for fusibility. |
| It has been shown that optical techniques can provide a quantitative measure of the fusibility of individual macerals. |
| The offspring of these three populations were tested for fusibility against both inbred lines by colony assays. |
| This process is the firing of the clay to a primrose or a white heat according to its fusibility. |
| Lead was probably used at first for its fusibility only, but afterward it was certainly introduced for economical reasons. |
| Felspar is much used in the manufacture of porcelain by reason of its fusibility. |
