diluting ferric chloride?
Hi,
Have been trying to etch copper but only had one consistently even result.
2 probs: I diluted with 25% water and now I've put it all back in the one container am wondering if I shouln't've.
I've been using Sharpies but having to renew design at least twice during process.
I remember once using some sort of plasticky wood sealant but have a feeling I may have had a clearout since then.
I'd appreciate any tips although I think I've had it with buying new pens.
Nick
