A uniformly hydrated composition is provided and methods of making the uniformly hydrated composition. The method comprises providing a plurality of lyophilized porous macroparticles in a chamber, the plurality of lyophilized porous macroparticles each having an average diameter from about 0.1 mm to about 10 mm and comprising ceramic material and polymer; and mixing each of the plurality of lyophilized porous macroparticles with a fluid in the chamber to uniformly hydrate each of the plurality of lyophilized porous macroparticles to form a uniformly hydrated composition. Hydratable compositions are also provided.
