I attemped a second warped record. This time I timed it for 1/2 hour sessions.
Things to consider:
- severity of the warp
- thickness of the record
- sun intensity
These points will determine how long to leave it out for. Also, after baking DO NOT handle the record. Bring the whole platform inside to cool down before handling it.
btw. the second baking was very successful as well and baking did not alter the sound one tiny bit.
