Metal Ore - Right at the very top of the volcano!
Glass - At the forge of the temple. You need either fine sand which is found on crystal island which you must unlock, or those bottles you get messages in.
Now for your main question - you need to have been on island three to get through that door. If you do not want a spoiler, then stop reading :D
On island three you find all of those hieroglyphics. Using your workbench you make them into one nice big one. You can then enter the two ancient doors on island three. Inside there is a crown near the two ruined seats. THAT is the key to the second island's door!
It's worth it to get in that door - it's a pretty site :D
Also in case you didnt know there is on the second island a rock on west beach near the coldesack with pineapples. Inspect it and oyur sim will move it out of the way. There is a hidden passage way wich leads to Pirates Cove and is wear Beard Beard's treasure is.
Actually there are several sandalwood trees around that hot springs and also about three of them in the geyser plains area. I am not sure about any other locations, but those I do know of.
On the volcano island, geyser plains, there are sandalwood trees everywhere. But you need a metal axe to harvest the wood.
You need to make a metal axe and then you find loads of sandalwood tree's in volcano island and geyser plains :)
The Sims Castaway is a version of the Sims where your Sim is trapped on a dessert island. You will have to help it back to sanity.
If you are wearing the crown you can pick up in the volcano temple, go back to the Dark Cave on Island 2 and inspect the door.
I think you're supposed to get all of the hieroglyphics and make them into Wall Art. Once you have, inspect the doors and you're Sim will know what to do.
Sandalwood - you need to have a metal axe to harvest sandalwood. If you don't have one then the option to Chop Sandalwood won't appear when you walk up to the trees. Sandalwood trees are mostly found in Geyser Plains and Volcano Jungle.
in the temple interior, you need all nine hieroglyphics, then you make an ancient steele, then go to the ancient door in geyser plains then click inspect.
Once you have the obsidon axe go up the little hill on the right side of the rock. Climd to the very top and inspect it.
