Gypsum panels and methods of making gypsum panels are provided. A method of making a gypsum panel includes combining gypsum stucco and a halide salt sequestration agent with water to form a gypsum slurry and setting the gypsum slurry to form at least a portion of a gypsum core, wherein the halide salt sequestration agent is present in an amount effective to sequester at least a portion of halide salt present in the gypsum stucco. A gypsum panel includes a gypsum core that comprises set gypsum and a halide salt sequestration agent, wherein the halide sequestration agent sequesters at least a portion of halide salt present in the gypsum core.
