Marble Sugar resin filler. A granular natural ground marble. Adds weight primarily and some coolness to resinous casts giving a feel closer to stone. About the same granular size as sugar and hence its name, may also be used in plaster to create special effects. Will also improve impact resistance and resilience. Not coated like BLR so will increase your vicosity as you add it, so be careful not to make your resin mix to thick by excessive addition. Start at 50% and work up or down to match resin viscosity to the job.
