Candy Glass!

Making candy is something I haven’t done much but I have watched my grandparents do it countless times and I’ve always enjoyed the final product! Candy glass, or sugar glass, was used in movie productions as fake glass that is easily, and more safely, shatter or jumped through.  Many high end restaurants and bakeries use candy glass as a garnish on desserts but it is pretty dangerous to make. My school  showed us how but was very adamant about safety measures we needed to take, if you were to let the “molten” sugar get on your skin, instant second degree burns will occur if not worse.  With that being said, I encourage everyone to keep a large bowl of ice water nearby. If an accident were to occur, dunk your hand/arm/whatever in the ice water to help limit the amount of damage being done.

Now that you have the background info and safety warning lets get onto the making!


  • Candy Thermometer with a clip
  • Baking sheet or silicon mold with walls at least 1 in high
  • Heavy duty sauce pan
  • Metal or wood spoon
  • Measuring spoons
  • Nonstick spray


  • 2 C water
  • 1 C corn syrup
  • 3 1/2 C sugar
  • 1/4 t cream of tartar
  • 2 t flavoring (if desired)
  • a few drops food coloring (if desired)


  1. Combine all ingredients except flavoring and food color. Heat on low! If you you have the heat too high it will discolor because you will begin caramelizing the sugars.
  2. Heat to the “hard crack stage”, 300 degrees F. This refers to the original way to tell how hot the sugar is by dropping some into cold water. If you don’t have a candy thermometer you can use this water technique, just make sure you do some research! At this point if you want color of flavor, quickly stir it in.
  3. remove pan from heat and quickly (and very very carefully) pour it onto the greased cookie sheet. gently shake and tilt the cookie sheet to spread the sugar out as evenly as possible.
  4. Let sit at least an hour, until completely hard. If you want one large sheet, use a hot knife to slide around the edges and carefully pry it up.  You can use an engraver to make a desired shape that the glass will crack around, to do this go over the outline many times, about a dozen, to ensure the cut is deep enough. I chose to shatter the glass and create a stained glass cookie cake
Cooking the sugar, water, and syrup mixture. You can see the candy thermometer that is clipped to the side of the pot. You will want to keep a close eye on it, it will take forever (figuratively) to get up to the correct temp but it will just the last 20 degrees or so!
This is the black glass. You can see some bubbles in it, this is because I didn’t shake it well enough, you can also use a needle or pin to pop these.
This is the red glass. You can see that one side is thicker than the other, this was done on purpose because I wanted a variety of shades.
finished cookie
This was my finished product, I created a giant cookie cake with buttercream icing which I used a a glue to hold the glass properly.
