  1. Hi Ellen

    I’m wanting to make candles with a concrete base that takes up about 1/4 of the candle length. Textured and semi rough look. What would be the best vessel / mould to use ?

    Tgan you

    1. Hi,

      If I understand correctly, it sounds like you want to have the candle directly on top of the concrete? One challenge is not getting candle oil from the wax to drip or absorb into the concrete. I recommend casting in reverse, so do the candle portion first and upside down. You can follow my tutorial for how I did the marbled pillar candles, and think of the first color I cast as the candle wax portion- instead of concrete: https://artsyprettyplants.com/diy-concrete-pillar-candle-holders/. Once the candle wax has hardened, you can do the concrete portion. You will want to make sure you don’t get candle wax on the side of the mold where the concrete will be, or the concrete will absorb it. It’s not the end of the world, it can be part of the look, it will be darker and blotchy in this areas.

      For the rustic part, there are two ways to get concrete looking rustic. One is cast it against a rough texture, the other is to not vibrate it much after casting. Vibrating eliminates air pockets which gives you a smooth outer surface. Not vibrating will possibly give you air holes or gaps. This is probably a trial and error thing. You can also remove the concrete early for a less smooth, matte look.

      The mold is up to you, but a less smooth mold will result in a less smooth appearance.

      I hope that helps!
