Assay

Assay N°1

193°C : beginning of the melting point

198°C : the melting point is complete

210°C: white smoke appears

240°C : test stopped, production of white acrid smoke

Assay N°2

170°C : the dye

193°C : début de fusion

199°C : the melting point is complete

238°C : white smoke

Applicant's summary and conclusion

Conclusions:
Under normal conditions of pressure, the melting point has been determined to be between 193 and 198 °C.
