What frustrates me with how-to guides such as this one is the lack of followable detail, the vagaries and lack of conciseness.

Take this phrase:

> I heated the iron hydroxide strongly to convert it into iron oxide.

What does this mean? What is "strongly"? Is 'strongly' putting it in the microwave for five minutes?

Sorry about that. I tried to keep it short, as the guide is long enough already. Since some of you have commented about that, I'll make some edits to it. Thanks for the feedback.

I heated it at 200C for 1 hour on a hot plate. You might need to heat a bigger batch for longer. Generally, I do double the time for it to get completely dry, to make sure all the iron hydroxide is converted to iron oxide.

Now this is extremely helpful, thank you!
