Background An investment can be defined as a ceramic material that is appropriate to form a mold into which an alloy or a metal is cast.The mold-forming operation can be described as an investment, which means a process of covering or surrounding material, such as a denture, wax form, crown, or other objects.The phosphate-bonded investment results in a brittle-cast model with the surface of a pore.The hardening agents of the dental surface are then used in materials of refractory investment to improve their properties.The problem of Statements: The phosphate-bonded investment results in a brittle-cast model with the surface of a pore.Objectives was to compare and evaluate the effectiveness of various hardening agents (Bee wax, paraffin wax, and soy wax) on surface hardness.Materials and Methods 28 specimens were created using «phosphate-bonded investment» materials.Each group had seven samples: group A (control without immersion), group B (immersion in soy wax), group C (immersion in paraffin wax), and group D (immersion in beeswax).After being immersed in wax, the hardness value of each specimen was determined.Results The results indicated that after immersion in various waxes, the surface hardness value increased for all specimens.Conclusion The immersion technique with a hardening agent considerably enhanced the surface hardness of the refractory investment materials.
