How to make this citric acid substance I made not sticky? So I made this solid material by boiling citric acid crystals and water then letting that cool to harden.  It hardened into this solid that is really easy to mold and is transparent but it has this really annoying sticky texture that I want to get rid of.  I don't know if its the water causing this texture or not but can someone tell me how I can get rid of this and whats happening?

Thanks
A vacuum oven with a solvent trap is a really good way to get rid of persistent water in your product. I'm not sure what your overall objective is so I'd read up on how aggressively (or gently) you can heat your product first though.
