<<Disclaimer: Verify this information before applying it to your situation.>> Hi folks, I've just been informed of some GF Icing Sugar (I'm not sure if the same term is used in the US) which is labelled 'Starch Free' with 'Natrolite as Free Flow Agent'. I've found no mention of Natrolite in the list's archives. A small amount of research suggests that it is a naturally ocurring silicate mineral, which in theory should be GF. Has anybody had any experience with this substance and care to make a comment on it? Thanks Simon Quirke New Zealand
