To prepare casting moulds, an aqueous solution of high concentration (8% or more) is used with the addition of glycerin or glycols, as well as a preservative to avoid gel surface contamination by moulds; bacterial contamination is impossible because a gel with such a high concentration has very little free water left where bacteria can grow (it has a very low AW). Both these matters will be discussed. 5% agar, is prepared in a similar way to the one used for the Nikan-Sui method but in a crystallizing dish (70 mm diameter, 52 mm high) to a level of 48 mm.
