can i eat this? noticed it shrunk when left out

So I bought this glycerin dab straw at a local smoke shop. It didn't come in a box or anything so I've been looking online about 1- how to chill it and use it safely without causing thermal shock and cracking any of the glass. Google tells me I should heat the nail before putting it back in the straw. That seems like a pain and impractical and a good way to get burned if you're not careful. Any advice on how I can get those frosty hits without breaking my piece? And 2- how to get the reclaim out to re-use? I'm reading that hosting it with a torch or even a lighter may be too harsh for the glass and alcohol removal and evaporation, heating with a hair dryer, or putting in a baggie and submerging in hot water then pouring out the reclaim are the best ways. Again...any advice or personal experiences that have worked best? Brand new to glycerin pieces and I'd rather hear from real people than Google. 😅 Thanks in advance!

Received some BHO from a friend but as someone who has only had live rosin i dont know if its any good.

What are your thoughts?

Smells good and tastes good without being harsh on the throat or lungs.

They say its done with some new bho tech but i have no clue what it means.

One month in the back of the fridge, pretty happy with the cure result.
