DEFINITION

Classification: 106/789

Slag:

(under subclass 638) Subject matter employing a composition containing slag.

(1) Note. As slag, a by-product from various metallurgical processes, is a relatively indefinite or broad term in the art, this subclass is intended to take compositions referred to as slag by the applicant and where appropriate the claims may also be crossed elsewhere based upon the disclosure by applicant as to the specific composition of the slag.
