## Guides

- [What is colloidal silver? A plain-English guide](https://yorkshiresilversolution.com/guides/what-is-colloidal-silver/): Colloidal silver is purified water containing very small particles and ions of silver, usually at a concentration of between 5 and 30 parts per million (ppm). It's normally made by electrolysis: a small electric current passes between two pure silver electrodes in deionised water and releases silver into it. In the UK it is not a licensed medicine.
- [What does ppm mean on colloidal silver?](https://yorkshiresilversolution.com/guides/colloidal-silver-ppm-explained/): ppm stands for parts per million. On colloidal silver it tells you the concentration of silver in the water: 1ppm is about 1 milligram of silver per litre. So a 10ppm colloidal silver contains roughly 10mg of silver per litre, which is about 1mg in a 100ml bottle.
- [Colloidal silver vs ionic silver: what's the difference?](https://yorkshiresilversolution.com/guides/colloidal-silver-vs-ionic-silver/): Both are silver in purified water. Ionic silver is mostly dissolved silver ions and looks completely clear. A true silver colloid is mostly tiny metallic silver particles held in suspension, which usually gives it a yellow to amber tint. Most colloidal silver made by low-voltage electrolysis, ours included, contains both, with a large share of the silver in ionic form.
- [How colloidal silver is made: electrolysis explained](https://yorkshiresilversolution.com/guides/how-colloidal-silver-is-made/): Colloidal silver is usually made by low-voltage electrolysis. Two 99.99% pure silver electrodes are placed in deionised water and a small direct current is passed between them. Silver leaves the positive electrode as ions and spreads through the water, where some of it forms tiny particles. The process is stopped when the solution reaches the target concentration, measured in ppm.
- [How to store colloidal silver, and how long it lasts](https://yorkshiresilversolution.com/guides/how-to-store-colloidal-silver/): Store colloidal silver in a sealed dark glass bottle at room temperature, away from direct sunlight. Don't refrigerate or freeze it, and keep it away from metal containers and utensils. Stored this way, it is best used within about two years of its production date. Throw it away if it becomes cloudy or develops grey or black specks or sediment.
- [How to choose a good colloidal silver: a buyer's checklist](https://yorkshiresilversolution.com/guides/how-to-choose-colloidal-silver/): Choose a colloidal silver that lists only purified water and silver as ingredients, states a ppm that the maker actually measures, comes in dark glass, and carries a batch number and production date. The maker should be easy to contact and willing to explain how it's made. Be wary of added salts or proteins, plastic bottles and any medical claims.
