When using IF YOU CARE® Parchment Paper and Baking Paper no greasing is necessary. The paper has been coated with silicone - a non-organic natural product - on both sides. Many parchment papers are coated with quilon. Quilon is a chemical containing chrome - a heavy metal - which when incinerated becomes toxic and leaves trace elements. The reason for the majority of parchment paper to be quilon-coated is the cost, which is substantially lower than silicone. So, in order to be environmentally friendly, the paper should be silicone-coated.
