Review: Cyanotype Toner - Using to tone my cyanotypes. Two thumbs up. Got sick of fumbling with tea and coffee so decided to try tannic acid powder. Never going back. Tip I’ve found: Bleach cyanotype first with soda ash and remember the toner dries darker. It tones fast so keep an eye on it. Review: Really worked well! - Our shepherds paw would not heal totally for about a year. We used this on advice from our Vet and it healed in about a month. We needed to cover with a protective tape but it worked its magic! ## Features - High Purity Reagent ACS Grade - Product has an Indefinite Shelf Life ## Technical Specifications | Specification | Value | |---------------|-------| | % Assay of Chemical(s) | 97 | | ASIN | B00DEVURR8 | | Best Sellers Rank | #90,932 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #79 in Inorganic Reagents | | Brand | ChemCenter | | Brand Name | ChemCenter | | Container Type | Drum | | Customer Reviews | 4.5 out of 5 stars 92 Reviews | | Item Form | Powder | | Manufacturer | RND Center Inc. | | Package Information | Drum | | Percentage assay | 97 | | Unit Count | 100 Grams | ## Product Details - **Brand:** ChemCenter - **Item Form:** Powder - **Package Information:** Drum - **Percentage assay:** 97 - **Unit Count:** 100 Grams ## Images ![Tannic Acid, Reagent ACS, High Purity, 100 Grams - Image 1](https://m.media-amazon.com/images/I/61nZ84RzY2L.jpg) ![Tannic Acid, Reagent ACS, High Purity, 100 Grams - Image 2](https://m.media-amazon.com/images/I/917TpIV9TOL.jpg) ![Tannic Acid, Reagent ACS, High Purity, 100 Grams - Image 3](https://m.media-amazon.com/images/I/61EsTce1H-L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Cyanotype Toner *by J***N on April 20, 2026* Using to tone my cyanotypes.
