Simmering Granules are our top seller for use in burners. They are replacing oils because they are simpler and cleaner to use. You do not add water. Simmering Granules are very economical. Two teaspoons will give fragrance for about 4 hours (the same as one of our quality tealights). A single packet will give you 24 hours of fragrance. Simmering Granules are produced in our own factory using high quality salt and fragrance oils. We usually dispatch orders withint 24-36 hours of receipt. Cinnamon and Orange is a familiar much loved scent which combines two of the best selling fragrances.
