Hi Julie! Thanks so much for purchasing one of our Solidteknics pans. Good news - a temperature of 230 degrees is perfectly fine to season your pan at. Alternatively, you can season it on the hob (smokey but effective). Furthermore, the pans do actually come lightly pre-seasoned with oil - some people prefer to use their pans straight away with fatty foods like bacon, which will create seasoning too. There are many methods to season a pan, so rest assured it's not a precise art!
