Our additives are mineral or simple chemical substances for which there is generally no minimum shelf life. When stored in a dry place and tightly sealed, they can usually be kept for many years. It is particularly important to protect them from moisture, as otherwise they may clump together or change their properties. You will find storage instructions in the respective product or safety data sheets.
In our online shop, we can only offer you some basic information about our products. If you would like to delve deeper into the world of plant dyes and expand or deepen your knowledge, we recommend our workshops at Hof Emschermündung or with one of our globally active dialogue partners.
That depends on the additive in question. We have compiled the most important information in general terms for you in the safety instructions on the respective product page. For a detailed overview of each additive, please refer to our product or safety data sheets. If you have any further questions, please feel free to contact us directly.
