Once that was done, she went back to where she had left the potion and took it out of the refrigerated box, and set it out, letting it thaw and reach room temperature again. This took a bit of time, so while she was letting that happen, she inspected it in several different ways, seeing if there had been any tampering or if there were any anomalies that shouldn't be there.
Unfortunately, this was the first time either of them had made this concoction, and while Roxanne would have been able to tell if there was something majorly wrong but if there was something minor was wrong, she wouldn't be able to tell at all.
They also did not have any high-tech equipment to inspect it at a deeper level which meant they were only able to do eye tests which were usually not very accurate unless something was really, really wrong.
