- replacing the composition by removing the first glass-based composition from against said area of the wound and placing against said area of the wound a subsequent glass-based composition also comprising a glass-based composition comprising from about 40 to about 90 wt % B2O3;
- and
- repeating said replacing and retaining steps so that said retaining is performed cumulatively for a period of at least 24 hours, said repeating of the replacing and retaining steps resulting in removal of the black necrotic eschar.
