What temp are you purging and drying at? I purge at 95F and dry at 85F for 4 hours then at 65F until it shatters. One thing I found with my oven was the shelves were warmer than the ambient temp so I put a silicone tray under my oil and the colors started looking a bit nicer.lol. thanks!
its all trick photography.
the first picture is extreme butane bubbles youre looking at. haha. that seems to be when my stuff it the prettiest... the vacuum chamber just kills its color!!!
and the fifth picture is also a ton of butane youre looking at. I poured my golden butane INTO a dish of room temp water. the water got very cold very quick and made ice and severly underpurged... thats what youre seeing in the pic before (or is it after?) the 5th pic there on the blade
