On my third extraction I put my tray out in the sun to evap the rest of the solvent. Brought it back in because it seemed to melt a little... put it under a fun and hours later I had a pile of goo. I scraped it up put it on a piece of cardstock and set it in the wire basket I have suspended over damp rid that I use to dry mushrooms. Next day, solid mass; no goo. its still a deep yellow color but I'm much happier with it now.
