On my first attempt to make hard candy I discovered that the selection of molds available locally was pretty limited. Either the molds were not for high temperature or they were teddy bears or lollypops. So I decided to make my own.
I have seen corn starch mold used for industrial candy production so I figured it was worth a try.
1/2 sheet tray - to hold the mold
1/2 sheet size cooling rack
Full Sheet tray - help to contain mess
Hot Glue gun
Corn starch - 4 lbs for 1/2 sheet tray
Square dowel to hold the positive shape
Some kind of positive shape that can be attached to dowel. I used 1" jewels from hobby lobby. I'll call them a die as you can use any shape that you can find to make the mold.
Calipers - if you are really a geek
Molten Hard candy - you can find multiple instructables on this topic
I measured the 1/2 sheet tray. It's inside dimensions are 17.25"x12.25".
The dowel is 36" long. I need it to be at least 13" long so it can be used as the 'stamp'. To make it easy I cut the dowel in half to 18"
