ok, i just bought some plaster of paris to make some sea shell molds. i have the sea shells to push into the plaster. i have never used plaster or made molds before, is there any tips i should know before i start.
i am going to place a layer of sara wrap between the plaster and the fondant when i make my shells for teh cake. just so what goes on the cake will not come into contact with the plaster
ok- i mixed up my plaster of paris, put vaseling on my sea shells and stuck them in the mixture. now how in the world do i get them out??? will they come out easy when the plaster is completly dry or should i try and pry them out while its still a little soft?
jjbrink-- I believe plaster molds are often broken after the casting is made. They are often not re-usable, except if the shape is very flat or simple.
Here's a link for a discussion of silicone molds, which are food-safe, flexible, and re-usable.
Sorry, I can't be of more help for the plaster molds.
petit- the link would not work. do you mind trying to send it again?
Here's some general info. on silicone molds:
Here's a neat one -- I love the idea for making coral without using a mold (scroll down to see the photo): http://forum.cakecentral.com/cake-decorating-ftopict-49675-silicone.html+mold
