Abstract

The present invention is directed towards methods comprising providing a frozen liquid, coating the frozen liquid with an aqueous calcium solution; and exposing the frozen liquid coated in calcium to an alginate solution to create a liquid container.

Claims

exact text as granted — not AI-modified
1 - 43 . (canceled) 
     
     
         44 . A method comprising:
 a) providing a frozen liquid   b) coating the frozen liquid with an aqueous calcium solution; and   c) exposing the frozen liquid coated in calcium to an alginate solution to create a liquid container.   
     
     
         45 . The method of  claim 44  wherein the frozen liquid is frozen water. 
     
     
         46 . The method of  claim 44  wherein the aqueous calcium solution comprises calcium chloride. 
     
     
         47 . The method of  claim 44  wherein the alginate solution comprises MA-alginate. 
     
     
         48 . The method of  claim 47  wherein the alginate solution comprises 1% MA-alginate. 
     
     
         49 . The method of  claim 47  wherein the alginate solution comprises a MA-alginate solution containing 0.1% photo initiator. 
     
     
         50 . The method of  claim 44  wherein immediately upon contact with the calcium solution, the alginate solution absorbs calcium ions, which causes solidification of the alginate solution. 
     
     
         51 . The method of  claim 44  further comprising the step of rinsing the liquid container. 
     
     
         52 . A method comprising:
 a) providing a frozen liquid;   b) placing the frozen liquid in a calcium solution; and   c) placing the solid in an alginate solution.   
     
     
         53 . The method of  claim 52 , further comprising the step of: (a1) further cooling the frozen solid in liquid nitrogen after step (a) and before step (b). 
     
     
         54 . The method of  claim 52 , further comprising the step of: (a2) placing the frozen liquid in an alginate solution after step (a1) and before step (b). 
     
     
         55 . The method of  claim 54 , further comprising the step of: (d) placing the frozen liquid in a calcium solution after step (c). 
     
     
         56 . The method of  claim 52  wherein the frozen liquid is frozen water. 
     
     
         57 . The method of  claim 52  wherein the calcium solution comprises calcium chloride. 
     
     
         58 . The method of  claim 52  wherein the alginate solution comprises sodium alginate. 
     
     
         59 . The method of  claim 52  further comprising the step of rinsing the liquid container.
