 Hi there,

       It is quite easy to make a lamp with a pickle jar, a metal lid, some 
metal tube, a wick and paraffin, to smoke paper. You clip the paper tightly 
onto the drum and rotate the whole thing over the smoky flame, till you get an 
even, totally black cover. The presence of the metal backing drum stops the 
paper from catching fire. When the trace is complete, you very carefully remove 
the paper and SPRAY THE BACK SIDE OF THE PAPER with hair lacquer, so that it is 
wet right through. When this has dried, you can also spray the front of the 
trace. If you try to just spray the front of the trace, a lot of the carbon 
blows away and you get a blotchy, uneven result. You get a much higher resolution 
from this type of trace than from an ink pen.

       Regards,

       Chris Chapman
