The crystal phase that crystallizes first on cooling a substance to its liquidus temperature is termed "'primary crystalline phase "'or "'primary phase " '.

If the desired glass property is not related to crystallization ( e . g ., liquidus temperature ) or phase separation, linear regression can be applied using common polynomial functions up to the third degree.
13.
The "'liquidus temperature "', T L or T liq specifies the temperature above which a material is completely liquid, and the maximum temperature at which crystals can co-exist with the melt in thermodynamic equilibrium.
14.
Magnetite has a higher liquidus temperature than the iron oxide ( " FeO " ) normally found in the reverberatory furnace slag and it precipitated, causing a growing accretion in the reverberatory furnace, thus reducing the storage capacity of the furnace.
15.
Glass chemistry has a huge impact on the process since it controls the melting, forming and annealing temperatures, liquidus temperature ( point where various chemicals that make up the glass start to crystallize out of the glass ) and rates of change of characteristics of the glass itself.

Gabbro may have a liquidus temperature near 1, 200 �C, and the derivative granite-composition melt may have a liquidus temperature as low as about 700 �C . Incompatible elements are concentrated in the last residues of magma during fractional crystallization and in the first melts produced during partial melting : either process can form the magma that crystallizes to pegmatite, a rock type commonly enriched in incompatible elements.
