Etched Copper Pipe - using PnP

So I found a container that was tall and thin -didnt want too big to waste any chemical
was a plastic container from my plastic ties

Because it was plastic I was not going to heat it up so I estimated it might take about 2 to 2-1/2 hours

I loved the fact that the PnP worked so well  so I expected a really good etch

I prepped the tube by putting in a rubber stopper on one end and filled it with some art sand for weight 

I partially filled the container and then put the tube in and then filled till it was really close to the top

I put a bend mandrel in the sand just to give me something to balance and taped either side 

this held the tube in the center of the chemical while it etched 

I put in at 8:20 and I took it out at 10 pm 

If it was heated and since fresh ferric it might only take about 1-1/2 hours to etch  - I find the heat does make it more aggressive and I guess there are times you want that 

I think when I do the stainless washers again I am not going to heat it up 

and let it etch for however long it takes  and keep my eye on it this time 

soooo - I pulled it out of the etch - let it drip and drain for a minute - took paper towel and took it to the sink and washed off and put some baking soda on it to stop the etch 

Nice Etch

Just had to clean it up to see what it would look like 

so I sandblasted the PnP off and I like the effect of the sandblasting - it takes all the materials from the pipe and all the grooves  - used a bit of Penny Brite and some steel wool 

Came up really clean with very little effort or additional chemicals for cleaning

Best results so far 

Going to cut them up and make beads
