i need tricks for recrystallization meth

Hello,

I have few questions about the recrystallization. I've tried with all solvents that i had access , ethanol and methanol looks to be the best .

With water , there's something that i miss for sure , i don't know what to do with it , ?

I just got ether , should i do it with this instead of ethanol and methanol ?

And toluene? if i mix water and toluene , where's my compound? how can i extract it ?

Should i wash it with acetone before starting the recrystallization?

Should i cover my flask wright after boiling and start to cool down?

Freezer , counter or ice bath is the best to cool down?

Is there'S tricks to make big and solids shards?

Do the erlemyer is a good choice the cook a small batch ?

hope someone will give me good tricks so i can finally make something good for me !

Thanks
