Sparkolloid
"Hot Mix Sparkolloid® is a fining agent developed by Scott Laboratories for clarification. It is a blend of polysaccharides in a diatomaceous earth carrier and has a strong positive charge. Hot Mix Sparkolloid® neutralizes the repelling charge of particulate matter allowing aggregation and formation of compact lees. It does not remove desirable color constituents. It is not a cold stabilizing, heat stabilizing or odor removing agent."
