Glass Cast 50 bubbles

Hi

I've been using Glass Cast 50 for a couple of projects and  I seem to get lots of air bubbles in the set resin. It looks great when poured.
I mixed by weight, clean mixing cups, stirred for 4 minutes and used a heat gun to remove surface bubbles. The room was kept at 20c
The picture is a side view of the layer.
Any ideas what I'm doing wrong?

I'm afraid degassing first then super extra careful when pouring as you don't want it to absorb air as you pour it.
