... impregnation of the mounting resin can cause edge rounding and also fill the unprotected edges with grinding and polishing debris. Unimpregnated areas in the specimens can usually be eliminated by vacuum impregnation of the sample with the mounting resin, along with a pressure cure. In this case, a dyed...

A possible problem arising from the use of high shrinkage mounting material or not allowing the mount to cool under pressure where required can be a gap between the sample edge and the mount. This condition often results in rounding of the sample edge and entrapment...

.... The selection of mounting material has a significant impact on edge retention and the surface flatness of the mount. Failure to use the proper mounting media may cause rounding of the interface between the mount and sample, resulting in poor edge retention. It can also cause rounding or faceting of the overall...
