How They Function

You may ask yourself why it can take up to one month for them to look so fabulous. This machine uses 4 stages to get a rock to look mesmerizing. Each stage has its own individual process so it takes longer to create perfection. Of course, you can add mineral oils and other items to make them look the way you want them too. Below you will find each stage explained and it will help you to understand this machine better.

  • Stage 1 – This is where shaping takes place. The grit will remove the rough edges and it will give the rock a round finish. It’s important to add plastic pellets if you don’t fill the barrel or if the rocks are fragile. At this stage, the machine is the noisiest as the edges are knocked off. If you put hard rocks inside, this stage can take up to a week. Whereas, with soft rocks, it may only last for few days. Decide on what shape you want them to have whilst checking the machine daily. After you receive the shape you want, clean the barrels and make sure that you don’t pour the waste down the sink.
  • Stage 2 – This is where the fine grit takes place. This stage will remove any visible scratches or cracks the rocks have. In addition to this, it will also give them a dull glow once the rocks are dry. Please make sure that the plastic pellets are cleaned squeaky clean before you put them inside if you want the rocks to come out perfectly. This stage isn’t very noisy but it will last about the same amount of time as the first stage. Nonetheless, you should check on the machine every single day in order to know the progress. Once the rocks are done with the thorough cleaning, then comes the per-polish.
  • Stage 3 – This gets more exciting as it’s near the end. By now, your rock should have a round shape without any visible cracks or dirt. It should also have a dull shine. In stage 3, the rocks will get silky smooth. The machine will bring out the luster from the rocks. This stage also takes about a week but the wait is worth it.
  • Stage 4 – After the last bit of cleaning, comes stage 4. The last stage. Here, the machine uses the grit that looks almost like fine powder. We recommend that you add some plastic pellets because you want to avoid the rocks getting hit by each other. It would be a shame to ruin them right at the final stage. After a week of your rocks being in this stage, they should come out looking mesmerizing. They should be bright and shiny. Almost like something that looks like you have just bought it from the gift shop.
