The plastic temps I have tested were 335 and 345.
I am not stirring... No glitter and no salt.
Tested again tonight. This time I heated the raw plastic in the pot rather than the microwave. After about 45 minutes it was up to temp and unfortunately, I achieved the same result. Previously, I was heating in micro and pouring into a fairly cold pot and then turning it on.
The bubbles are extremely small! It's not the plastic because when i heat in the microwave the baits are perfectly clear.
