testing transfer times from blue film onto pickled copper (not scoured). cheapo iron max temp x 30 sec plus futzing time; straight into cold running water. i’m hitting that point somewhere between cotton and synthetic on my bigger iron in the studio.
now set samples for 30 mins, 45 mins and 60 mins in the heated etch bath, suspended face down. yay blue foam \o/
as for heating, i’m managing pickle and etch in one of these heated, divided lunchboxes.
indicator light doesn’t work but it does heat and what do you expect for a tenner? 😀
