Sealants, vacuum insulated glazing (VIG) units having seals formed from the sealants, and methods for producing the VIG units using the sealants are provided. The sealants include a mixture of glass materials in powder form, a foaming agent in powder form, and a carrier medium. The foaming agent includes carbon black, carbide(s), or a combination thereof. The glass materials have compositions including: 50 to 70 wt. % SiO; 1 to 7 wt. % CaO; 0 to 7 wt. % MgO; 0 to 6 wt. % AlO; 1 to 6 wt. % FeOor FeO; 0 to 7 wt. % TiO; 0 to 16 wt. % RO, wherein R is chosen from the group consisting of Li, Na, K, or a combination thereof; 0 to 1 wt. % SO; 0 to 2 wt. % MnO; and 0 to 6 wt. % SrO+BaO.
