Airborne debris - Issue? How to avoid?

i'll give it a crack...

i see tane in there. in pics 4 and 5 of the oil disc, notice the haziness when the light is going through it. not the bigger bubbles, but the slight opacity in some areas. i've always thought that kind of area is the residual tane, while the bubbles that are bigger may be one of several things. more tane, air that was trapped as it was scrapped off the plate or onto the parchment or it could be the elusive terpenes.

but the cloudiness, which is just slightly there, is why it looks like it could have another 15 minutes (or more) purging.
