Glycerin/water based liquid marbles formed using polytetrafluroethylene (PTFE) and treated fumed silica powders show excellent thermal robustness on hot surfaces (50-150 0C). This thermal robustness of liquid marbles can allow reactions at high temperature. We will present behavior of liquid marbles on hot surfaces with other novel properties like their transparency. Surface treated nanoparticulate fumed silica powders form transparent liquid marbles which allow for optical interrogation for concentration, crystal growth etc. We will also present drying of liquid marbles as potential way to controllably assemble meso/micro spheres of polymers and other solids.
