Emissivity of ferrite? (doing infra red thermometer reading)

[treez]

Hello,
What is the emissivity of the surface of this ferrite?

MSD1583 sepic inductor:

.....I need to know in order to set the emissivity on the infra red camera.

could you say if it will be like aluminium, or more like the plastic of a dpak body.
Ferrite surface is dark (implying high emissivity) , but somewhat smooth and thus shiny (implying low emissivity).

You can expect quite high IR emissivity (> 0.9). If you want to check it yourself, you'll surely find how to after thinking a bit...
