Abstract: A method of preparing a plasticized sulfur composition of increased viscosity as compared to a mixture of molten sulfur and remelted plasticized sulfur concentrate, which comprises including and mixing 0.01 to 5 weight percent of a C.sub.2 -C.sub.25 saturated polyhydric alcohol with the mixture. The concentrate used herein is obtained by combining sulfur and a sulfur plasticizer and then solidifying. Preferably the viscosity is increased sufficiently by the inclusion of the polyhydric alcohol so that the mixture of remelted concentrate and added sulfur will not give substantial sagging upon spraying onto a vertical wall in a thickness of about 1/16 inch.
