Topics Covered In This Video:
* I get asked about those black streaks many times every week, so I know this is a very common problem with many clayers.
* Originally I thought it was grease coming from the rollers. But that is not the case.
* Those black lines are actually caused by scratches in the chrome plating on the pasta machine rollers, that is reacting with the chemicals in the polymer clay.
* Basically the metal scratches are oxidizing which can leave a black residue on the metal surface.
* The residue then gets transferred to the clay.
* I removed the fins from the pasta machine to show you how the rollers work, but I have an older machine that can be taken apart. Don't take apart newer machines because they may not go back together! You've been warned ;-?
* Over time the rollers on the low end pasta machines get lots of scratches where the scrapers rub against them.
* Scratches tend to be on the outside edges of rollers due to scrapers bending in the middle.
* On the cheaper pasta machines/clay conditioning machines from Sculpey and Amaco, the chrome plating is low quality, and the rollers age and oxidize quickly.
* I used to suggest cleaning with Rubbing Alcohol, but I think that actually that makes things worse.
* Now my suggestion is to run some scrap translucent through your machine, which works to pick up up the black streaks. Then you can put your good clay through rollers.
* Once clean, it takes a while for oxidation to build up again.
* My theory on tools... a low end machine will do you well enough until you prove that you will use it enough to justify buying a higher end machine. In other words, buy cheap to start, then if you use it so much that it it breaks... buy the best you can afford at that stage.
* My next pasta machine purchase will be the Atlas 150 - Wellness Series with Anodized Aluminum rollers that are guaranteed not to leave black streaks.
