Here at the End of the Earth borax is still freely available. I suppose I should stock up on it, as well as incandescent globes. Making some chemicals unavailable is not altogether a bad thing: my...

If it's yellow, it has something else in it. Maybe the vendor could clarify. I've only ever had it white.

I use home made Ilford ID-78 in a 12x16 Nova slot processor. I find that FB paper absorbs a surprising amount of developer so I have to keep topping up. That keeps me going for some days: I tend to...

The Fotospeed FX30 is relatively odourless because its pH is close to neutral (6.5 according to the MSDS).
