Ok...I hope this makes sense about what I am asking. I am wanting to make a design to put on top of a cake and I know that Color Flow tends to melt if it is sitting upon BC for very long so I was wondering if you could use Royal Icing to make the design. Has this been done before?
I use royal icing flowers on cakes. I also made a cake this week with pirate stuff on it that I had made with royal icing and it did fine also.
I don't know how long it would last on the "grease", but I do know that the items I have used lasted at least 18 hours. (time it was frosted to time it was picked up) HTH
I'm no expert, but I have used colorflow on my cakes before. I saw on a post one time that if you use all crisco buttercream that it won't break down. The jungle cake, the birthday present cake, and the Darth Vader cake are cakes that I have used colorflow. I do it, let it dry, then attach it to the cake with a little royal icing or buttercream.
I use the color flow techinque often with royal icing. I don't keep the color flow mix on hand as I don't use it often enough.
Color Flow mix is essentially the same ingredients as Royal Icing Mix, but with a strengthener (and I think a drying agent) added to it.
It responds to grease the same way as Royal, but more slowly. If I want to be on the safe side, i.e. the piece needs to be pushed into the cake or must stand up, I put piping gel on the buttercream/cake contact points. For insertions, I pipe in Royal and then stick in the Color Flow. Another recommendation is to elevate the piece slightly by using mini marshmallows pushed into the icing on the cake and then gluing the piece with royal to those.

I dont think it will be a problem. I have put royal icing and colorflow on buttercream many times and it doesnt turn into a mushy mess or anything. The only thing I did notice on one occasion was a colorflow piece (a spartan in my photos) that was on top of BC. It was there for awhile, like 24 hours, and I did notice some speckles on it from what I assume the grease soaking through it. It really looked fine and it wasnt a goopy mess or anything. It was still hard. I think the books and the wilton classes make everyone all freaked out that the royal icing will turn into a blob if it comes into contact with royal icing. It will be fine.
