What's the best way to remove concentrate from ceramic container?

I just completed my second batch of QWISO using all my trim and I'd like to know how to get my concentrate out of the crock pot I used for purging. The first batch I made turned out more like Rick Simpson Oil than the dabs I was wanting so I'm probably gonna use my pyrex dish of oil for a half pound of cannabutter. For my second batch I just poured my iso solution into the ceramic pot of a 2qt crock pot and now I need to figure out the best way to get it all out.

I also learned a lot my first batch. I put my trim in a Magic Bullet and turned it to dust, I let my trim sit in iso for too long, I didn't use a screen to remove plant material and skipped straight to running it through a coffee filter which lead to more time soaking in iso, I tried not heat purging and just left it to sit out with a shirt covering and fan blowing over it for a week and ended up tasting iso when I smoked it, when I did heat purge it I guess I burnt it because it tastes like when you burn bud in a dry herb vape (or light bulb vaporizer when I was a teenager). Overall it resulted in a smoke that gets you high but it's unpleasant to get there so I fixed all of that and my second batch is so much better.

I would upload a picture of each but every time I try it says there's an error on the picture for the second batch.
