So, I have this project coming up in a few weeks and I have decided to feature a house with a fountain in the front of it. It's supposed to be a "mansion - like" piece, so I thought the fountain would be a nice touch. 

Anyway, I drew the fountain I wanted to make, on a piece of paper. I was going to just sculpt it using gum paste, and then glaze it with my shiny mix - (which I have done lots of times) but I thought it would be even more amazing if I would make it out of glass. And thus the anxiety begun... LOL!

The issue (and premise for this question) is, I don't have a mold to make my idea come to life. Working with glass in the past, Iv'e used a couple of "stained glass window" molds, and Iv'e used basic silicone shapes to build anything else I would need - and then just simply either glued or torched the edges together. Iv'e never made my own mold or cast, and I have no idea where to start. The project itself is on a smaller scale so the fountain will probably only be around 5 inches length, &  2 inches width. I am capable of sculpting on fondant, gum paste, and even clay (outside of the kitchen). I also have worked with pulling sugar. But I just haven't been made aware of anything I can sculpt on, and then use as a sugar mold - especially since we're talking about trying to make a mold for a 360- degree symmetrical figure with sugar that can reach 400 degree + temps!  This would be a little bit easier if I wasn't starting from scratch - but I wasn't able to find a small scale fountain to my liking that I could just simply mold with silicone - and I want to be creative with this piece.

If anyone has any ideas, videos, or even other treads that would help me out - that would be awesome!

I haven't attempted anything like this before either, but there are plenty of tutorials online for mold making. One idea that seems feasible is to sculpt your fountain out of air-dry clay, then use food-grade silicone to make a mold. 

It's quite pricy but it seems to do the job. This one seems to have good reviews:

If you do decide to go this route, please post photos of the finished cake - it sounds like it's going to be quite impressive!

Good luck :)

I saw a tutorial several months ago that showed how to use old fondant to make a mold.  Not sure if it was a Craftsy video or what, but just google it and you shoud be able to find it.  It was so much cheaper than silicone, and worked perfectly.  I haven't tried it yet, but it might be worth a shot!  Good luck!

y'know what -- i would make a bowl shape and twist a piece of pretty sugar for the rim -- and blow or fashion a little piece for the stem and make the stand on the bottom -- if you have already done that much with sugar -- you can do this --

idk -- i already have various molds & things i could use to fancy it up --

i think a sparkling sugar fountain is more life like -- much easier to produce -- grey for concrete --
