|Concrete candle holders made from Pringles cans and a coffee can|
Molds for concrete projects are really easy to find. Many household containers can be used. I stay away from items that can not be easily cut away if the concrete gets stuck. Nothing is worse than struggling to release your piece. Plastic is usually my first choice-but I will give just about anything a try. With this project I chose some Pringles cans and coffee cans-which are not really cans at all. They are cardboard sides with a metal bottom. The metal bottom is important-it prevents the weight of the concrete from sagging and making an uneven bottom on the finished product. Here is a pic of what I mean:

There are many different containers that you could use for this project-just raid your recycling bin. You will also need molds for the inside-something a little bit larger than the candle you want to use. I used small condiment containers and a lid from my cooking spray. Here are some containers and interior molds that could be used:
1. A concrete mix or recipe (A good "recipe" for this project: 1 part portland cement/3 parts sand/
1/2 part water-I use a cottage cheese container as measurement )
2. Good quality mask
4. Bucket or tub to mix in
6. Mold release spray-I use cooking spray.
To start this project you need to spray the molds with the mold release and then wipe it off. You do not want a heavy coating of it-it will cause excess air holes if excess is not wiped out.
After 10 minutes you can begin filling your molds-don't fill it all the way.
Tap the sides to release air bubbles:
To clean up fill your tub or bucket with water and let it set until the sediment settles on the bottom. After it has settled you can pour the water off then scrape the sediment up and put it in a bag and dispose of it. Never dump concrete or the sediment down the drain. It will ruin your drains.
When the concrete is set pull the interior molds out (it is easier when the rocks or sand are dumped out). Here I used a pair of pliers:
For a smooth finish on top you need to sand it. I just use a sheet of snadpaper and rub it until it is smooth:
