In oceanic scatter, a water-soluble bag containing bone meal dissolves immediately when it gets in water, so bone meal disappears from view in a blink of an eye, so that a feeling or emotion as a ceremony It is hard to feel.SOLUTION: The oceanic scattering ice block 100 is characterized by including bone meal mixed ice 90 obtained by freezing bone meal mixed water obtained by mixing bone meal and water. The base material ice 10 filled with the bone meal mixed water 5 in the through hole 15 is stored in a freezer or the like (not shown) and the bone meal mixed water 5 is frozen in the bone powder mixing ice 90 to obtain an oceanic scattering ice block 100 . According to the ice block for oceanic scattering, we can perform oceanic scattering that can reduce labor and cost while adhering to the feeling and emotion as a ceremony.(FIG.【課題】海洋散骨にあっては、骨粉を収容している水溶性の袋は着水すると直ちに溶解するために、骨粉は一瞬にして視界から消えてしまい、セレモニーとしての風情や情緒といったものを感じにくい。【解決手段】海洋散骨用氷塊100は、骨粉と水とを混合した骨粉混合水を凍結させた骨粉混合氷90が、含まれることを特徴とする。貫通穴15に骨粉混合水5が満たされた基材氷10は、不図示の冷凍庫などに収容し、骨粉混合水5を骨粉混合氷90へと凍結させることで、海洋散骨用氷塊100を得る。海洋散骨用氷塊によれば、セレモニーとしての風情や情緒を堅持しつつ、手間やコストを低減できる海洋散骨を行うことができる。【選択図】図3
