I have made a vintage truck out of gumpaste to lay on top of a sheet cake. I used various dusts, silver glaze, and edible varnish and need to know if steaming to set the dusts will mess up the silver and varnish.
I assume that you put the glaze/varnish over the dust(s). If so, they are "set".
I don't steam anything that has been glazed or varnished. It just creates pock marks.
If it's still in question, take a piece of scrap gum paste or fondant & test it.
Thanks for the response, that is what I thought. To make the body of the truck shine, would rubbing it lightly with shortening work? I am new at this, so any suggestions would be greatly appreciated.
The shine from shortening is pretty transient.
I have been told, but have never tried, that a mixture of 1/2 lemon JUICE and 1/2 clear corn syrup brushed on will yield a nice shine. I suggest trying it on a scrap piece of fondant
Thank you BlakesCakes for all of your suggestions. Being a Newbie, I need all of the help I can get. I do not want to do anything that will mess up what I have done. When I finish the cake I will post pictures.
