YOU'LL NEED.....
1) A large mixing bowl
2) Suitable moulds to shape the bath bombs
3) Kitchen scales
4) A hand sprayer containing clean cold water
INGREDIENTS
300g Bicarbonate of Soda
100g Citric Acid
10ml Fragrance or Essential Oil of your choice
Colour (food/cosmetic/soap liquid colours are fine. Also powders i.e. ultramarines or oxides)
HOW TO.....
Measure out the bicarbonate of soda and the citric acid into the mixing bowl, seiving if necessary and thoroughly mix together until you have a consistent texture.
If using liquid food or cosmetic/soap colours, add, in drops, enough colour to make the shade you want, mixing it in quickly to avoid it fizzing up.
If using a powdered colour, simply add, a little at a time, until you have your desired colour.
Measure 10ml of either fragrance or essential oil into mixture. Most essential or fragrance oils will not cause the mixture to fizz, but certain citrus oils may, so if this happens, mix in quickly and thoroughly.
Do not leave the mixture to stand or it will slowly start to set.
Now, a little at a time and working the mixture all the time, spray a little water on it with the hand sprayer. Mix continuously to avoid it fizzing-up in the bowl and ONLY ADD ENOUGH WATER TO HAVE THE MIXTURE START TO HOLD TOGETHER WHEN LIGHTLY SQUEEZED IN YOUR HAND.
Once this point is reached you need to work quickly to compress the mixture into your moulds.
If using our Bath Bomb moulds this mixture will make almost exactly 5 bath bombs using the 2 inch moulds. You will need 3 moulds, without clips, in halves, ready to fill. Fill each half just proud of the surface and press together for a few moments. Then remove one half, being careful not to let the bath bomb fall out and leave to set in the remaining half for 15-20 minutes. You should end up with 5 bath bombs sitting in 5 half moulds with 1 half mould left, into which you can press any left-over mixture if you wish.
You can choose to use all kinds of moulds including something simple like ice-cube trays or small yougurt pots.
After 20-30 minutes they should be quite hard. Simply take the bath bomb from the mould and leave it to dry.
There! You've made bath bombs. Wasn't that easy!
HINT... Beginners will usually find Granular Citric Acid easier to use. To improve the look and texture of the bath bomb, use Powdered Citric Acid, although care needs to be taken not to use too much water or they will start to 'grow' before they set hard.
