Patience... Once the Alumisol is fully melted, let it sit in the microwave for 1-2 minutes without turning the microwave on. Then turn on the microwave for 30 seconds. Again, let it sit a full minute or two without stirring, then turn the microwave on for 20-30 seconds, then let it sit for 1-2 minutes. Repeat until all the bubbles have popped from the top and you are ready to pour your bubble free Alumisol. Basically you are trying to keep it at 375 degrees F consistenly without cooking it anymore. Within 5-6 minutes on a 3 cup batch it should be almost if not completely clear. The more softener that is added, the quicker it degasses itself.
