You can move the loupe anywhere you want. Also, you can hide the magnifier loupe by clicking the 'switch' button (placed in the bottom of the image).

You have the possibility to zoom in the spectrum by selecting a spectral region you need to be increased (along axis x); to zoom keep the left mouse-click continously pressed, drag (to left or to right) and release the left button. To return to the initial size spectrum, press the right click on the spectrum -> Zoom -> Reset View.

Interpretation of the black pigment Raman spectra

For the raw black ceramic from Hoiseşti (and this sample from Scânteia), the paste used was a clay rich in organic substance. Through the firing process, the organic substance turned into black carbon. The Raman spectra of these samples clearly indicate the presence of black carbon, being similar to the spectrum of a black ceramic sample from Isaiia (Precucuteni culture).
