I've looked through this thread which was really useful.
I used to buy it pre-mixed, I remember it was dark green in translucent plastic white bottles.
Now I have bought a bag of 250g of pellets that's meant to make up 500ml of solution, but at first I only want to etch a small single sided board. How much do you think I should mix up?
Should I mix the lot and store it or mix it in small batches? What's the smallest practicle size to mix?
A few days later I may want to make 2 or 3 more similar sized boards.
