Method of making glow-in-the-dark terrarium substrate

Abstract

The present invention involves a glow-in-the-dark edible terrarium substrate for a terrarium animal such as a reptile, an amphibian, or an arachnid. The substrate is a glow-in-the-dark calciferous sand including a calciferous sand with a glow-in-the-dark coating. The glow-in-the-dark calciferous sand is healthy, ingestible, and digestible by the terrarium animal and provides lighting for observing the nocturnal behavior of the terrarium animal.

What is claimed is:  
     
         1 . A method of use of calcium carbonate as a glow-in-the-dark edible terrarium substrate in a terrarium including a terrarium animal, comprising: 
 providing glow-in-the-dark calcium carbonate sand including calcium carbonate sand with a glow-in-the-dark coating; and    using the glow-in-the dark calcium carbonate sand as a floor covering for an animal terrarium, whereby the calcium carbonate sand is healthy, ingestible, and digestible by the terrarium animal, and to provide lighting for observing the nocturnal behavior of terrarium animal.    
     
     
         2 . The method of  claim 1 , wherein the sand is a fine granular sand.  
     
     
         3 . The method of  claim 2 , wherein the sand is a screen controlled calcium carbonate filler.  
     
     
         4 . The method of  claim 1 , wherein the sand is at least approximately 95% calcium carbonate, no greater than approximately 3% magnesium carbonate, and not more than approximately 5% other acid insolubles.  
     
     
         5 . The method of  claim 1 , wherein the sand has a pH of approximately 9.0-9.5.  
     
     
         6 . The method of  claim 1 , wherein the sand has a specific gravity of approximately 2.71.  
     
     
         7 . The method of  claim 1 , wherein the sand has a Moh's scale hardness of approximately 3.0.
