Thanks! Great info!!!
Here's another silly question... Can I mix the first developer as I use it? For instance, if I get a 1L kit, can I mix 500ml first dev and use within 2 weeks, then later mix the remainder in a second batch? Or has it started deteriorating as soon as the stock bottle is opened? Would the butane lighter trick discussed in other threads be of use here?
Never mind, I found the Private Preserve wine preservers and ordered some. Something that can preserve both my wines and chemistry, now there's a fine product!
I'll try it on a 1L kit, and if that works OK I'll try it on a bigger kit.
