In this file, we are delving a little bit more into the different parts of a bath bomb. Understanding why different colours are used will take your products to the next level in appearance and performance.
Its outside shape, colour, and smell are what 90% of people decide upon. Bright colours (if that is your aesthetic) Painting, drizzle, botanicals, glitter all help.
Some people use only water-soluble dye for this stage and this works with some blooming and skill. (Please see blooming note at bottom of the file) Others boost the colour with Neons, Mica and Lakes into the mix which is to only help colour this part of the bomb.
This part is when the bomb is put in the water and when all the ‘magic’ and ‘performance’ happens. Those amazing rainbows and bath art as the bombs go whizzing, spinning and shooting around spewing colour and excitement.
Water-soluble dyes are used for embeds and to colour foam and the water.
Once everything settles this is the final colour and part you actually get to soak in, and sometimes this is overlooked. We get so focused on the rainbows or unusual clashing of colours that sometimes the water leftover can be a less than desirable colour. Think browns and yellows and yeah... it is not great. Colour charts can help you a lot with this and the design stages (such as yellow and blue bombs will make green water... red and blue will make purple water)
Water Soluble dyes are what gives this tub its final soaking glory, mica can be added to give a glitter appearance in the water. A newer trend is to use a large amount of Fluorphlogopite mica to give the water an almost liquid metal appearance.
Note on Red and Black-
These are the hardest colours to get a rich intense colour using only water-soluble dyes. This is because you are starting with a white base so this instantly turns these into pink and grey. Because these colours are normally wanted in dark/solid it is recommended a higher use than the other dyes.
This seems like something that comes up a lot once you start making a few batches of bath bombs. This can also impact to different degrees depending on where you live of course. Ideally, you want the humidity of your drying area to be below 35% and a dehumidifier can help if you have an enclosed space to dedicate to your bath bombs.
