10lb BAG OF 99% YELLOW SULFUR POWDER SHIPPED VIA Fedex IN ITS ORIGINAL BAG! Feed Grade Sulfur is recovered during gas manufacturing as a molten sulfur. It is then cooled on a stainless steel belt and forms into a flake form. The flakes are then taken off the belt and ground into sulfur powder. The sulfur is without additives and is regarded as safe as Animal Feed / an additive to animal foods. It is not considered suitable for human consumption. Feed Grade Sulfur has many uses:Additive for Feedstock / Animal ConsumptionRids of pests (spread into a garden to scare away snakes)Kills/Repels Insects (keeps ticks off a dog’s hair)Burning of sulfur kills insects with sulfur dioxide fumes Sulfur is insoluble in water. Only mixtures in water can be made. Sulfur powder has a low flammability rating. It can be compared to wood in terms of flammability. When burned, it creates sulfur dioxide, a poisonous gas which can cause harm to animals and may also cause many health hazards if burned in large quantities (acid rain is one of them). In the old days, people used to burn sulfur powder to remove pests and clean out fields. Note that pure solid sulfur powder does not burn easily because it requires a lot of oxygen to get a sustainable blue flame. The only way to make it burn well is to mix it well into the air. This can be done with a specially made sulfur burner.
