I have just made my first 'slab test' using Naturewax C-3 & 8% fragrance oil,
when it had set (pic1) it didn't look right on the surface so i melted it for a min or 2 under the grill (pic2),
now its set again it has a smoother top but has swirly marks in (pic3), can anyone explain what this is or why its happened?
Thanks in advance.
