PnP -on Pipe ? - applying PnP on Pipe for etching

Well after reading this months Jewelry Artist and the Chris Darway article  (page 20)  - I just had to try applying PnP sheet to Copper Pipe.

I took two sizes of copper pipe and cut them down (picked up at Home Depot)
I really like this cutter - leaves and nice end - no puckering like the other pipe cutters 

Nice and clean

I use 000-0000 steel wool to clean the surface
and I cut the PnP to fit 
Now at this point as much as I am going to wrap in silicone tape  I need something to hold it while I do 
so I taped the sides 

 Just put small pieces at either end and in the middle
I wrapped the silicone tape (plumbers white tape - you can get at home depot)around the pipe - tightly 
I have a Hot plate that I use for the my application of painted glass to beads so I plugged it in and set it to low as I was not sure how hot I needed to get this to work - 
I also put a probe on the hot plate just to see what the temp was 
so I stood them up on the heated surface hoping that the heat would flow up the tubes 

I reversed them but could not get them to stand so put one inside the other and let stand for another 20 minutes to 1/2 hour  - they didnt seem really that warm (even though it said 345 degrees F)  so I eventually laid them flat (one inside the other) on the plate and hoped for the best 
Totally forgot for about an hour (I am getting really bad at this ) 

I unwrapped the silicone tape -  the PnP looked dark like it does when I use the press 

OMG it worked 

Its about 90% perfect - some small areas that need touch up but nothing major 

What the PnP looked like after I took it off 

I applied the Stop Out (another liquid resist) to the tiny areas needed and letting it dry 
will etch hopefully today just have to get a container tall enough (bought a bunch of drink containers from dollar store  - I have one rubber plug for the larger pipe but I have to come up with something for the other 
going to fill with sand to make it heavy and the plug will not allow any ferric into the inside where I dont want to etch 


  1. Thanks for explaining this process so clearly. Yours is the first blog I have found with such complete and clear directions.

  2. Oh My God, you are brilliant! I love the simple, clear and concise. Thank you.

  3. So what kind of toner printer did you use for the pnp. Have had no luck with that material. even on a flat surface. Any hints would be much appreciated.

  4. Can you get Pnp that is already printed?

  5. Can you get Pnp that is already printed?

  6. Can you get Pnp that is already printed?

  7. Can you give a complete list of everything needed to etch. Love it. Thanks.

  8. What is pnp n were can I get it.

  9. What is pnp n were can I get it.

  10. what can I use instead of hotplate? Thank you, Kris

  11. Perhaps you can lay it down flat on an electric griddle and roll it back and forth with chopsticks! You can use plastic from a butter tub for the ends-just hot glue or even epoxy to the tube, and cut it off later.
