Need a household oxidizer easy to get.

[Lok]

All I need is an oxidizer, for a bit of DIY bluing. It requires water an oxidizer, a base (soap is best :P), and 100'C or more.

All I can think of till now is matchheads which contain quite a bit of KClO3 which might work. As it can be separated by dissloving it in water.
Anybody know of anything else.

Thanks in advance.

Might Oxiclean (sodium percarbonate) work? It's a bit unstable when dissolved, though. You'd have to heat the solution before adding it.

Yup. Need to read a few labels from the cleaning cabinet.
I've already done it with fertilizer, but am of short supply right now, for a few weeks.
