Put Aluminium Foil in the top brewing spot and Mercury(II) Chloride in the bottom to get Aluminum Amalgam

Put Aqueous Methylamine Solution in slot 2 of the crafting table, Phenyl-2-propanone in the center slot, and three Methanol surrounding it to get Imine Mixture 

Then brew Aluminum Amalgam and Imine Mixture to get Amine

Brew together Amine and NaOH Solution(Sodium Hydroxide Flakes and Water Bucket crafted) to get Methamphetamine Base

Then put Methamphetamine Base surrounded by Hydrochloric Acid and Toluene to craft Unpure Methamphetamine

Finally smelt Unpure Methamphetamine in a furnace to get Meth
