I heat it in the microwave for 10s, stopped, then another ten (it bubbled slightly at the end), but when I removed it, even though the bottle was quite warm, the temp strip read black.

I heat it in the microwave for 10s, stopped, then another ten (it bubbled slightly at the end), but when I removed it, even though the bottle was quite warm, the temp strip read black.
