# Infusion

*Infusion* is a special feature of Paydirt [Non-Fungible Tokens (NFTs)](/virtual-items.md#non-fungible-token-nft). It enables Paydirt NFTs to contain tokens like [Paydirt Gold](/paydirt-gold.md) or even other NFTs. In Paydirt, this feature is primarily used to *infuse* [Paydirt Gold](/paydirt-gold.md) into Paydirt NFTs representing gold items.

Behind the scenes, [Paydirt Gold](/paydirt-gold.md) is *infused* into every [Gold Nugget](/virtual-items/collectibles/gold-nuggets.md), [Gold Coin](/virtual-items/collectibles/gold-coins.md), [Gold Bar](/virtual-items/collectibles/gold-bars.md), or any other gold [blockchain-enabled item](/virtual-items.md#blockchain-enabled-items) whenever it is converted to [Non-Fungible Token (NFT)](/virtual-items.md#non-fungible-token-nft) form (through [Import & Export](/import-and-export.md)).\
\
In other words, every Paydirt NFT representing a gold item is *infused* with [Paydirt Gold](/paydirt-gold.md) when it is created or minted. The NFT becomes a container for the [Paydirt Gold](/paydirt-gold.md) ERC-20 token and ownership of the NFT is ownership of the tokens contained within it.\
\
The amount of [Paydirt Gold](/paydirt-gold.md) infused when an item is created or minted is equal to the item's *gold weight,* which is the amount of *pure gold* it contains.\
\
Infused items may also be [melted](/paydirt-gold/melting.md) to recover [Paydirt Gold](/paydirt-gold.md).\ <br>
