Firemaking is one of the longer skills on Royalscape that i have mastered so i'll help you guys out if your new to FM.
Recommended skills: 61+ woodcutting.
First we'll do just with a tinderbox and logs.
Tinderbox code is 590
1-15 Regular logs, code 1511
15-30 Oak logs, code 1521
30-45 Willow logs, code 1519
45-60 Maple logs, code 1517
60-75 Yew logs, code 1515
75-99 Magic logs, code 1513
Firemaking that way is wayyyyyyyyy longer then firemaking while woodcutting with a "Inferno adze" (13661) which i'll guide you through now
Since the requirements of a Inferno adze is 61 woodcutting you can already access the majority of trees to cut, with the inferno adze you can burn any log without the fm level requirement.
1-60 Maple trees with inferno adze
60-99 Yew trees with inferno adze
The reason why i say yews from 60-99 right here is because by the time your 60 fm your woodcutting level will be good enough for yews.
or 1-99 Maple trees with inferno adze
or 1-99 Yew trees with inferno adze
I recomend 1 of those options above if your a lower wc level i recomend just doing maples, as yews take a while to cut.
Hope this helps.
