If you're having trouble melting the BTMS, there are a couple of reasons why this could be: - You have stored your BTMS somewhere cold, causing it to take longer to heat up and melt OR - You live somewhere cold which has also affected how cold your BTMS is before you try to heat it up and melt it If you are struggling with this stage, we would recommend trying to melt the BTMS in the ‘Oil Phase’ rather than the ‘Water Phase’. Water takes longer to heat up than oil does, therefore, if you put it in the ‘Oil Phase’ you should be able to heat it up and melt it much more quickly!
