42mm Aluminium Bath Bomb Mould
This lightweight and durable 42mm bath bomb mould can be used easily and effectively many times. Its small size allows for foot fizzies or bath bombs for smaller baths, adding greater variety to your range with 50mm & 60mm also available. With a very low chance of significantly damaging the them, these aluminum moulds are recommended for those who will give them continued use. The moulds themselves have no interlocking edges (as seen with our Plastic bath bomb moulds) but their flared lip does make for easy pressing together with easy line up.
Simply overfill both sides of the mould with your bath bomb mix, hold over your bowl, and compress together. Twist slightly to assist the line up. Remove carefully from the mould and allow to dry in a non-humid environment for 24 hours.
Run a hot bath, add the bath bomb and enjoy.
