What is claimed is:  
     
         1 . A crystal substance, which is formed by precipitating as fibrous aggregates by making a metal aliphatic carboxylate dissolve completely in pure water to give a solution, stirring, and gradually cooling the solution.  
     
     
         2 . A material for recovering oil flowing into rivers, lakes, marshes or the sea, which comprises the fibrous crystal aggregates according to  claim 1 .  
     
     
         3 . A crystal substance, which is prepared by precipitating as fibrous aggregates by making a metal aliphatic carboxylate dissolve completely in pure water to give a solution, adding an aqueous solution of an inorganic salt containing the same metal as in the metal aliphatic carboxylate, stirring, and gradually cooling the solution.  
     
     
         4 . A material for recovering oil flowing into rivers, lakes, marshes or the sea, which comprises the fibrous crystal aggregates according to  claim 3 .  
     
     
         5 . A method of preparing a fibrous crystal substance, which comprises the steps of: making a metal aliphatic carboxylate dissolve completely in pure water to give a solution; stirring; and gradually cooling the solution, thereby precipitating as fibrous aggregates.  
     
     
         6 . A method of preparing a fibrous crystal substance, which comprises the steps of: making a metal aliphatic carboxylate dissolve completely in pure water to give a solution; adding an aqueous solution of an inorganic salt containing the same metal as in the metal aliphatic carboxylate; stirring; and gradually cooling the solution, thereby precipitating as fibrous aggregates.  
     
     
         7 . A method of solidifying waste tempura oil, which comprises the step of: adding the fibrous crystal aggregates according to  claim 1  to waste tempura oil, to solidify the waste tempura oil.  
     
     
         8 . A method of solidifying waste tempura oil, which comprises the step of: adding the fibrous crystal aggregates according to  claim 3  to waste tempura oil, to solidify the waste tempura oil.  
     
     
         9 . a method of solidifying edible oil, which comprises the step of: solidifying edible oil, by using the fibrous crystal aggregates according to  claim 1 .  
     
     
         10 . A method of solidifying edible oil, which comprises the step of: heating a solidified complex containing solidified edible oil, obtained by the method according to  claim 9 , to decompose the solidified complex to regenerate to its original metal aliphatic carboxylate and edible oil.  
     
     
         11 . A method of solidifying edible oil, which comprises the step of: solidifying edible oil, by using the fibrous crystal aggregates according to  claim 3 .  
     
     
         12 . A method of solidifying edible oil, which comprises the step of: heating a solidified complex containing solidified edible oil, obtained by the method according to  claim 11 , to decompose the solidified complex to regenerate to its original metal aliphatic carboxylate and edible oil.
