Add the essential oil blend to the glass attar. For example, mix 1 oz. of vanilla with 1 oz. of lavender essential oil to create a warm and sensual scent.
Add the polysorbate 20 to the attar. This is an emulsifier, but it also works as a thinner that allows the oils to heat up without creating black sooty smoke.
Add the mineral oil to the attar. Secure the lid on the attar and shake it vigorously for 30 seconds to assure the contents are mixed thoroughly.
Remove the lid from the attar. Aim the looped, thick wick over the opening of the bottle and ease it into it. This part should dangle from beneath the cylindrical stone.
Push the stone disc firmly into the mouth of the bottle. For a bottle with a 1-inch opening, use a stone that is 3/4 inch in diameter. It should fit snugly into place. Secure the lid of the glass attar and allow it to sit for one hour.
