I unfortunately came after the appointment of thought, nor to ask the seller for a water drain hole, "unfortunately" the goods had been shipped super fast, so this could not be more bored by the company. Czaja (it was at my request very quickly replied). Therefore, I have even resorted to metal drills, but also not a big problem posed (7 holes with 4mm each in "Floral Pattern"). That the shell was something dirty on delivery, is for everyone who knows in the metal sector something actually normal (rust not as fast).
After cleaning with brake cleaner (a cheaper by 1.50 / large can) and some kitchen towels (also not expensive ...) I have the fire bowl with Camino flame Ofenrohr- / Stove paint (up to 690 C) sprayed in gray around the good piece visually enhance a little more (looks very good even without paint out) and to have a corrosion protection at least for the first time outdoors.
Oh, and do my burning wood and the shell very well ;-)
