Claim 16:
17. A method of analyzing a solid dissolvable article, wherein the method comprises:
providing a solid dissolvable article comprising a water-soluble block copolymer;
capturing an image of a surface of the dissolvable article using a three dimensional imaging device;
processing the image using a contrast function;
producing a data set representative of at least one of roughness, pore volume, depression volume and elevation volume, with the processed image;
determining a measurement of at least one of pore density, surface roughness depression volume and elevation volume of the surface of the solid dissolvable article;
determining dissolution of the solid dissolvable article; and
correlating the determined measurement of at least one of pore density and surface roughness of the surface of the dissolvable article to the dissolution.
