Diamond Dust Sparkling Deco Powder – Sweet Gold 90g 5 "Mica Powder for Cakes" Dawn 24 June 2020 I've used mica powders in crafting for years and was thrilled to buy this edible version. It is a Mica dust and should really be fluffed over an area with something like a paint brush. I used it on chocolate decorations and got the most luxurious, regal results. I bought a plain iced birthday cake and put a (clean) stencil on the top. Dusted this powder lightly through it and the result was a stunning glimmering rose. Nothing more was needed. Don't use the pourer, don't wet it unless you are painting with it then glycerine is best. This is a dressing and best used dry for beautiful results.
