  • Anyone use Canode blue for scraping?

    I have heard it is easier to clean up. is that true?

    It comes in such a large bottle... do you have to use more?

    Does it show up as well as prussian blue?

    It is water-based, I understand, does it make rust?

    Basically, if you have used both kinds, do you prefer Canode or prussian?

    I've been using it since the early 70's love the ability to wash it off with water, also used Prussian bluing when it was necessary, also used red lead which I still have a peanut can half full of. Canode comes in small bottles about 2 ounces IIRC, there is a variety of colors available. It works as good as PBing, never saw any rust, you can rub it out so there is only a hint of color, and you don't use any more than Prussian bluing, and its cheaper than bluing, and if you accidently ate it won't hurt you might have technicolor poop for a while (LOL).

      Prefer the Canode mainly cause it comes in other colors then blue. My eyes have hard time seeing the light blue color and the red shows much better for me when the pigment gets thin. The clean up is a big plus.

        It's good stuff. I taught my classes using both Prussian blue and Canode.

        The advantages are not clear cut. I think Prussian blue is bit more sensitive in thin films but Canode cleans up easier - otherwise it's a coin flip.

        Canode blue as a transfer medium and Canode yellow as a contrast medium is a hard combination to beat since red lead has been taken from the scraper hand's pigment armementarium. I've used yellow ochre as a contrast medium but its a bit abrasive. Scraped tooling has to be tuned up oftener. Canode has the advantage of coming pre-mixed and ready to use. Prussian blue comes ready to use but contract media has to be made up by the scraper hand or imported from Italy. PITA.

        I think Richard King uses Canode exclusively in his classes.

        I prefer Prussian blue myself but I suspect my preference is more inertia than technical merit.

          I thought prussian blue counted as an anti-heavy metal medication?

          'According to the International Atomic Energy Agency, an adult male can eat at least 10 grams of Prussian blue per day without serious harm.'

          So remember, Don't eat more then a small tube of prussian blue a day.

          *thinks.. 10 grams* I wonder how many times a day you would need to lick your surface plate clean before that would be a problem?

            I have some Red, Blue and Yellow. If you see my latest post it will be getting some heavy duty use soon. It does clean up nice. Mcgyver has some but he never told me how it liked it.

              +1 for easy cleanup. It will dry out sitting all day but you can spritz it and rejuvenate it. From the way foam rollers suds up when being rinsed out I suspect Canode has a soap component which probably helps keep it fresh and maybe promotes spread-ability.

                Thanks... Now I have to find a seller... Dapra has a high minimum, apparently.

                  JT,
                  I got mine from a supplier in Michigan. They were not really quick but the 8oz bottles were very reasonable.
                  Since it will not have to cross border you will get yours much faster. I will try to find the details. Don't email them, call them they are old school.

                    JT,
                    Searching through my emails from 2010 found this one from Dapra.


                    Unfortunately we have discontinued the spotting ink.
                    Please contact the E.S Dyjak Company*@ 248+684-4260
                    They are locateded in Michigan and should have ink still available.

                    These guys are where I got mine. I think they are the supplier.

                      This is canode red and yellow used as a contrast medium with some very good home made prussian blue scraping medium as the blue...

                      Precision takes time.

                          When Dapra didn't have what I needed, I got mine at Volk Corp:

                          http://www.volkcorp.com/category.aspx?categoryID=104

                          NOTE: When ordering online, the 1.5 oz. size does not have a color selection pull-down option like all the other sizes.

                          At the time I was looking for canode ink in yellow. I visited Volk and clicked the 1.5 oz. and didn't get an option for anything but blue, so I looked elsewhere for another supplier. Luckily, another member on this forum or PM pointed me back to Volk and by selecting one of the other sizes, I saw the color selections. They have canode ink in blue, orange, red, white and yellow.
                          Cheers,
                          Gary

                              Canode washes off. Prussian Blue permanently stains everything: the surface plate, your skin, your clothes... Plus because it's oil based, it binds with the cast iron swarf and makes a nasty lapping paste.
                              Rich bans prussian blue from his classes, for good reason.

                              Richard: nice spotting! I use the blue/yellow. Might have to try the Canode red
