Locate and collect together all of your ingredients and equipment. Nothing worse than being part way through and discovering you need something else that you need to stop to get. This is a fair quick make up recipe, so everything needs to be to hand.
I found it easier to use a wooden stick like a lollipop stick that a lot of beauticians use for mixing. I could just throw it away afterwards then.
It's good to have the witch hazel already in a spritzer or spray bottle ready to go too.
Sieve bicarbonate of soda and citric acid into a bowl. Add desired flowers, colourings (I used a coloured powder originally used for colouring icing on a cake I made. Using something I'd already got and it's got good results.), and essential oils.
I've given a rough guide of the amount of essential oils to use, but really it depends on what you use and how strong you would like it. I used both rose and jasmine, unfortunately the rose has over powered the jasmine a bit.
Make sure you give this a good mix, otherwise your finished product will be a bit uneven.
Spritz lightly with witch hazel. Mix together until the mixture does not crumble when squeezed. The fizzing sound can be a bit off putting, certainly scared me a bit when I started. It soon dies down though. It's just the ingredients all working together.
Press into moulds. If making two halves to make a whole, apply a small amount to the middle of one and then press both together.
Really the bath bombs should come out of their moulds pretty quickly and onto greaseproof paper, but I found this a bit tricky to be honest. They kept falling apart. I found the easiest way was to use a piece of paper bigger than the mould but not too big and I laid it over the mould and flipped it over VERY quickly and close to it's final resting place. Both the paper and the bombs stayed in place pretty well and they stop crumbling!
The bath bombs will need at least 48 hours to thoroughly dry out. I found mine fizzed for a bit before calming down after about 20 minutes.
Using this recipe I got 3 decent sized heart shaped bombs, but how much you get depends on what mould you are using. I made two different fragrances here, lavender in the lilac and I used a dusky rose colour for the rose and jasmine. Worked out quite well I think.
