Claim:
1. A testing apparatus for qualifying a composition for use to reduce scale deposition, the apparatus comprising: a first reservoir capable of holding a first fluid containing chemical inhibitors to be tested; a second reservoir having an approximately flat bottom plate having an upper surface and a bottom surface, the second reservoir is disposed within the first reservoir, the second reservoir capable of holding a second fluid; wherein the second reservoir is configured for the approximately flat bottom plate to be at least partially submerged in the first fluid for the first fluid to be in contact with the bottom surface so that a scale deposition from the first fluid is deposited onto the bottom surface of the approximately flat bottom plate; wherein the second reservoir is configured for the approximately flat bottom plate to be rotatable at variable speeds imparting shear stresses onto the first fluid in contact with the bottom surface.
