Orders and medals manufacturing techniques

[Stepanovich]

It doesn't look like a thin layer of enamel on these medals. How do they heap the power for the ORS? The enamel looks at least 1-2 mm think in the center of each arm.

There is a simple answer to your question. The enamel powder is applied as a water based paste. It can be applied in miniscule spaces with a tiny brush. (An eye dropper is also used for the watery paste)It can be applied in thick layers and it can be re-applied over other layers to build up the finished product.
