Another question, using the ammonium chloride solution which is different to the normal acid mix, is there a standard method of applying this solution, I find that giving two separate coats gets the rust going between boilings, is this the norm as there are no instructions in the Angier book, just wonder what you guys do. To get in awkward places with wire wool and where a brush won't go I use wooden disposable chop sticks which I wrap wire wool on on the end of the stick to card the soot off, any cleaning carding tips you guy's have/ use?
Quite a deceiving process as after every carding the piece looks like it's stiil in the white (but it's not until you put it up against a bright polished piece) only untill you apply oil on the piece after about 5 rustings then it really does turn out to be a dark finish. Apart from that I am hooked.
