41. So, at first the temprature is going to rise steadily, until you hit the melting temperature . 42. It rises into the solid mantle rock, lowering its melting temperature and causing the rock to melt. 43. The mechanism usually becomes dominant at temperatures greater than approximately one third of the absolute melting temperature . 44. Chemists still lack fundamental understanding of how ionic liquids work, even simple properties like the melting temperature . 45. The maximum working temperature of plaster is, so higher melting temperature materials would melt the plaster mold. 46. The BOLS model calculates the melting temperature for individual atoms from the sum of their cohesive bonds. 47. The technique fails on substances such as sapphire, whose melting temperature is greater than 3, 600 degrees Fahrenheit. 48. It has a softening temperature of 257�F ( 125�C ) and a melting temperature of 313�F ( 156�C ). 49. This natural tree resin from the East Indies gives the mixture a higher melting temperature and makes it harder. 50. The molds sometimes contaminate the molten metal by transferring their own material into it at the high melting temperatures .
