Instead of trying to measure directly into the hot container, pre-measure each batch of ingredients (5g beeswax, 25g cocoa butter, 50g oil) and store them in separate containers. This way, you can quickly add them to the melting pot without getting burned or needing to handle the hot container. Once melted, you can use a ladle or a heat-resistant syringe to transfer the balm to your containers. This provides more control and avoids spilling hot liquid.
