Edible Sea Glass tutorial


– 2 cups granulated sugar
– 2/3 cup light corn syrup
– 3/4 cup water (at room temperature)
– 6-10 drops food coloring (we used green, blue & varying combinations of both)
– 2 teaspoons flavoring (we tried chocolate, which was very mild and peppermint, which turned out to be the most flavorful. Next time I’d like to try a berry flavor…)
– cooking spray (veggie oil, don’t use olive oil, yuck!)
– confectioner’s sugar
– candy thermometer


Spray a small cookie sheet with cooking spray. (I found that if I wanted a nice thick sea glass, I had to set a small square cake pan on my cookie sheet to halve the surface area).

Attach the candy thermometer to the side of a small or medium non-stick pot.

Add the sugar, corn syrup, and water. Heat over medium and stir until the sugar dissolves.

As soon as it starts to bubble, DON’T TOUCH IT, let it bubble away until the thermometer reads 250-275 degrees.

Add the food coloring, but don’t stir. It’ll take care of itself. (And be careful of spatters: ie: no children allowed).

Let it bubble until the thermometer reaches 300 degrees. Remove from heat.

Add your flavoring, again being cautious of spattering.

Pour (CAREFULLY) into your prepared cookie sheet. Let cool (for about 1-2 hours).

And then (the FUN part), cover with a dishtowel and whack intermittently with a mallet or rolling pin (check often to make sure you’re not making sugar dust).

Pull out the cracked bits & pieces, and sand sharp edges (you can do this by just rubbing with a pot-holder or dishtowel).

Put confectioner’s sugar into a small bowl and rub each sea-glass piece with the sugar to give a matte look.

Stay Fancy! ;)


  1. It looks like you have parchment paper in your cookie sheet/pan. Is that true or am I seeing things? I want to try this for our Submerged VBS this week. I don’t have a candy thermometer though and I’m not sure I want to buy one.
