This work describes controlled experiments to fabricate materials emulating some of the properties of nuclear explosion fallout debris material, which is formed under extreme conditions that can be challenging to recreate on a laboratory scale. Debris composition is of interest for the information it potentially can provide in nuclear forensics analyses applied to the detonation of a nuclear device.  Controlled pore glass (CPG) has been loaded with elements of interest as a substrate for preparing surrogate nuclear explosion debris-like particles that mimic some qualities of debris. The CPG material was loaded with 20 elements of interest. The material was heat treated and the volatility of the elements was assessed. The CPG material was then analyzed for elemental concentration using ICP-MS. The experiments were repeated to assess the method reproducibility. Once reproducible methods were established the CPG was loaded with U-235 to create a fission products material as well as a selection of metals (Au, Fe and Ni) to generate an activation products material. This two fold presentation will describe the synthesis methods of the loaded CPG materials as well as present the results of the irradiated CPG materials.<br/>
