[Soda ash](https://www.materialinsights.org/commodities/soda_ash/) (commodity) and [Sodium silicate](https://www.materialinsights.org/chemicals/sodium_silicate/) (chemical): 2 relationships.

## How they are linked

### 1. Feedstock

*Physical flow · Direct · Soda ash → Sodium silicate*

Sodium silicate is made from soda ash: it is one of the raw materials its production routes start from.

### 2. Price link: product made

*Cost and price · Strong · Both ways*

Sodium silicate is made by fusing soda ash with silica sand, so soda ash is its main chemical cost. The two proxy indexes move together, monthly moves at 0.30 and yearly moves at 0.70, as cost changes pass from soda ash into silicate prices.

- **0.30** monthly change correlation
- **0.70** 12-month change correlation
- **0.86** fitted elasticity
