soap making - air bubbles

Hi Everyone!

I'm a beginning soap maker (Melt & Pour technique) and I have a problem with
air bubbles which constantly appear in my soap base, doesn't matter if the
base is clear or opaque. Till now I was only trying to melt the soap in the
microwave (I know, I know, very amateur:-). I stir it very slowly, but still
the bubbles are there, already when I take the melted base from the
microwave.

Any advice is welcome:-)

Thank you!
