Abstract:
1. A method for measuring the cooling curve of melts and/or the heating curve of melt samples with an optical fiber, comprising the steps of providing an immersion end of the optical fiber with an at least partially free surface, surrounding the immersion end with a spacing by a temperature-resistant sample-receiving chamber, immersing the optical fiber with its immersion end in a melt, thereby forming a sample in the sample-receiving chamber, thereafter pulling the sample-receiving chamber with the sample and the optical fiber out of the melt, and measuring a cooling curve of the sample and/or measuring a temperature profile during heating after previous solidification of the sample, the measuring steps being performed with reference to a signal obtained by the optical fiber and forwarded to a measurement device, wherein both an immersion end face and a portion of a side wall of the immersion end of the optical fiber are brought into direct contact with the melt.
