There is now a brush tip pen for porcelain! The brush tip makes it easier to "flow" as you write. You can write large or small text; it all depends on how firmly you press down on the pen. Method: Start by cleaning the porcelain thoroughly (then do not touch the surface to be decorated, as your fingers will leave grease marks). After that, you can start writing. If you are not satisfied, wash the object and start over. When you are satisfied with the text, let the paint dry for 4 hours, then harden the porcelain for 90 minutes in an oven at 160°C.
