There are more words but they are from Tolkien's earlier conceptional periods. Tolkien likely changed these words as he evolved the aesthetics and completeness of the languages. You may even find languages that Tolkien later rejected. Do not mix words from different time periods unless you are familiar with the phonetic developments.

Qenya 

kulo

noun. flame

A word for “flame” in The Etymologies of the 1930s under the root ᴹ√KUL “golden-red”, but this word was deleted (EtyAC/KUL).

kulu

noun. gold (metal)

The Etymologies of the 1930s had a pair of words kulu “gold (metal)” and kulo “gold (substance)” derived from the root ᴹ√KUL of similar meaning (Ety/KUL). However Tolkien revised the meaning of this root to “golden-red” and the derivatives of the root became color words: ᴹQ. †kullo “red gold” and ᴹQ. kulda or ᴹQ. kulina “flame-coloured, golden-red”.

Conceptual Development: The Qenya Lexicon of the 1910s had ᴱQ. kulu “gold” under the early root ᴱ√KULU of the same meaning (QL/49). The word ᴱQ. kulu “gold” reappeared in the Early Qenya Grammar and English-Qenya Dictionary of the 1920s (PE14/46, 71; PE15/72) before being abandoned in The Etymologies of the 1930s, as noted above. In later writings, “gold (metal)” was Q. malta.
