ABSTRACT OF THE DISCLOSURE This invention presents a preparation of expanded sili- cate-based aggregates as useful in a method for absorbing hazard- ous liquid materials This expanded silicate-based aggregate ma- terial has previously been known for use as insulation, fireproof wallboard and insulating blocks, high temperature pipe covering, fire proofing of steel structures, marine deck filler and for ce- ment block in non-bearing fire walls, but not for absorbing hazard- ous liquids. The present invention uses this aggregate material, either alone or mixed with a solution of five to seven percent of polyvinyl chloride in a solvent comprising 15% dimethylsulfoxide and 85% methylethyl ketone providing a paste which may be placed on a hazardous liquid material and within seconds will absorb the hazardous material throughout the thick paste material.
