Start by weighing out then sifting all your dry ingredients together,
excluding the colouring agent (baking soda, citric acid, tapioca starch, Epsom salts).
Weigh out your fractionated coconut oil, and add essential oils of your
choice. Pour the oils over the dry ingredients, then us your hands (gloves on
please!) to bring the mixture together, but don’t overwork it. You’re after
something that resembles wet sand, holding its shape when pressed together.
Divide the mixture into two separate bowls, then add your colouring agent to either one or both.
Take half a bath bomb mold, add a small spoonful of one mixture, then gently pat it down, then a spoon of the other mixture, gently pat that down too, and so forth, until the mold is slightly rounded and over-filled.
Repeat with the other half, then bring them together, and press firmly. When you bring the halves together, they should be so full that it takes a little bit of a squeeze to get the halves to meet.
Tap the top half with the back of a spoon, then remove. Repeat on the other side.
Repeat until you’ve used the entire mixture up.
From here – you can either transfer to an airtight container and allow a full 24 hours to set, or, you can place them on a tray in the middle rack of the oven, set to low/warm (<50˚C/122˚F) for four hours.
Done! Add one bath bomb to your bath once filled.
