INGREDIENTS & CONSUMABLES

Some ingredients you'll need, Loes Bogers, 2020

The recipes listed on this website can be used as a starting point for material makers in the Netherlands and around. Consider per ingredient if this is something that is locally abundant in your area. If not, try finding something that could substitute that ingredient to make it your own, and follow the local natural resources around you.

With these 40 ingredients you can list all the 25 recipes suggested as a material archive starter, with a suggestion for a local supplier and approximation of the cost per unit. Check out the tools section as well, this list contains disposables only. For under € 500 you can purchase all the ingredients listed below, and most will last many rounds of experiments. The prices listed per material sample in the recipe section are based on the prices below. Of course it is possible to buy smaller packages of most ingredients, this will be relatively expensive, but wise if you are planning to just try it out.

Locally abundant ingredients to collect

Selecting the 24 recipes to start with in the Netherlands were mostly motivated by what is abundant here locally. So the ingredients listed here involve food waste and byproducts that ideally should not be purchased, but sourced by accessing waste streams or collecting leftovers. If you start out doing this from home, it really helps to collect nice glass jars, pots and bowls for collecting and drying food waste. Remove the labels and give them a nice place e.g. in a window where you are reminded and where you can keep an eye on them as they dry.
