The Marble technique is a very demanding technique if you want to do it right. Therefore, I want to give you a little insight into how I personally do it and thus found my best method for marbling.
First, one stirs a JESIN measure (Powder & Liquid), which in and of itself is creamy white.
Depending on the colors you want to use for marbling, pour a small amount of extra and color it with LIQU-MENTS (in the photos it is the color SEAWEED). Then you add this dyed JESIN back into the original JESIN mass and stir it just a little until you already have a nice marbling in the cup.
And here's the trick I use for super beautiful marbling!
It is important - when you pour the marbled JESIN in the mixing cup now into the silicone mold - a very specific hand guidance during the pouring.
In contrast to single-color pours, where you can also simply hold the cup in a position above the mold so that the JESIN flows into the silicone mold, you should now specify the marbling course with a graceful hand movement.
To put it in concrete terms:
Do not stay with your hand on one spot and let the JESIN flow from the cup into the silicone mold. Thus, you also achieve a beautiful effect, but it is very different from the real marble creations.
You can get really nice marble by pouring along the silicone mold with the hand motion of pouring, meaning you start pouring on one side of your silicone mold and the motion with the cup ends on the other side of the mold. You are thus going with the flow.
As usual, you can remove your creation from the mold after 20 minutes. If you do not master it perfectly the first time - do not worry - no master has fallen from heaven. Practice!
