Teachsoap.com's Basic Bath Bomb Recipe
Gather your ingredients:
• 1 part Citric Acid
• 2 parts Baking Soda
• Witch Hazel
• Coloring of your choice (I used both rose clay and liquid colorants and the clay worked better by far, giving the bombs a beautiful muted pink shade)
• Fragrance Oil of your choice (I have used both lavender and rose geranium. Both are nice but I like the lavender a little better)
• Dome Shaped Mold (You can also use a meatballer for a smaller size)
1. BLEND BLEND BLEND BLEND the citric acid and baking soda – this step is super important – if you don’t blend well, you end up with a grainy bomb. We actually use a mixer on our larger batches. (I use both a whisk and my hands)
2. Once you’ve blended really well, add your colorant. Dry pigments or a specialty bath fizzy colorant like La Bombs work best – don’t add too much though – the color shows up once you add the witch hazel.
3. Add fragrance oils to your personal nose preference. (Again, I just add this to the witch hazel)
4. Now, this is the difficult part. Spritz (with a squirt bottle) the witch hazel onto your batch while stirring with the other hand. When your batch sticks together when squished, you need to start putting it in molds – time is of the essence. If you wait too long, the mixture will get hard. If you spritz too much, the mixture will be too wet and “grow” (start the fizzing reaction) on you. (I give it 5 squirts at a time and then mix really well before I squirt again. The mixture starts to look a bit like fake snow and feels a little colder for some reason when it’s ready for molding.)
5. Put the bombs in molds – wait a few minutes and tap them out. Let them air dry for 3 or 4 hours and voila! Wonderful, hard bath bombs. The harder you pack the bath bombs, the more dense, heavy, and durable bomb you will get.
