Made of wood, gold or glass: 'aus' + material in German
To say what something is made of, German uses one short word: aus, followed by the material with no article. Der Tisch ist aus Holz. means The table is made of wood. The same pattern works for Gold, Glas, Leder, Plastik, Stein and many more materials.
English speakers often try to translate made of word for word. The results are phrases like gemacht von Holz or von Gold, which sound wrong or unclear. Some learners also add an article, as in aus dem Holz. In German, aus alone already carries the meaning made of, so you rarely need anything else.

How it works
The basic pattern is thing + sein + aus + material. Think of aus as out of: the table comes out of wood. Because the material is meant in general, as a substance, it takes no article. The same thing happens in English: you say made of wood, not made of the wood.
Der Tisch ist aus Holz.
(The table is made of wood.)
You don't need a verb like machen. You can also attach aus + material directly to a noun, which is short and very common. It works like English a wooden table or a gold chain.
Ich habe eine Kette aus Gold.
(I have a gold chain.)
Ich suche einen Tisch aus Holz für die Küche.
(I'm looking for a wooden table for the kitchen.)
The words
Everyday materials
Holz, Glas, Plastik, Stein, Papier, Pappe (you'll also hear Karton), Keramik, Porzellan, Ton, Wachs and Gummi all follow the pattern.
Die Flasche ist aus Plastik, nicht aus Glas.
(The bottle is made of plastic, not glass.)
Das alte Haus ist aus Stein.
(The old house is made of stone.)
Die Tassen sind aus Porzellan.
(The cups are made of porcelain.)
Die Kiste ist aus Pappe.
(The box is made of cardboard.)
Metals
Gold, Silber, Eisen, Stahl, Kupfer, Bronze, Messing, Aluminium and the general word Metall behave the same way. For buildings, Beton, Marmor and Granit fit here too.
Mein Ring ist aus Silber.
(My ring is made of silver.)
Die Brücke ist aus Stahl und aus Beton.
(The bridge is made of steel and concrete.)
Clothes and fabrics
Leder, Wolle, Baumwolle, Seide, Leinen and the general word Stoff are the ones you'll see on clothing labels and in shops.
Meine Jacke ist aus Leder.
(My jacket is made of leather.)
Das T-Shirt ist aus Baumwolle, der Pullover aus Wolle.
(The T-shirt is made of cotton, the jumper of wool.)
Watch out
No article is the default, not an absolute rule
When you add an adjective, the adjective takes a dative ending, because aus always takes the dative: aus massivem Holz, aus reinem Gold, aus echter Seide. When you mean one specific material, an article is fine: aus dem Holz einer alten Eiche (from the wood of an old oak).
Der Schrank ist aus massivem Holz.
(The wardrobe is made of solid wood.)
Avoid von
Ein Ring von Gold sounds old-fashioned. Ein Ring von Anna means a ring from Anna or a ring belonging to Anna. Use aus for the material.
Gemacht is possible, but usually unnecessary
Aus Holz gemacht and aus Holz hergestellt are grammatical. They are wordier, though, and hergestellt sounds technical. In everyday speech, ist aus Holz is enough.
Two common alternatives
German often uses compounds: Holztisch, Goldkette, Lederjacke, Plastiktüte. There are also a few material adjectives, such as golden, silbern, hölzern and gläsern. They are useful to recognise, but aus + noun is the safest choice for you.
Double meanings
Some of these nouns also have other meanings. ein Glas is a drinking glass, ein Stein is a single stone, der Ton can also mean sound, der Stoff can also mean substance, and ein Gummi is a rubber band. As materials after aus, they appear without an article.
Summary
To say what something is made of, use aus + the material noun with no article: ist aus Holz, eine Kette aus Gold. Don't translate made of word for word, and avoid von. If you add an adjective, give it a dative ending: aus massivem Holz.
