Global supply chain issues?

A DIY mindset can make you more resilient

The more complex your supplier's supply chain, the more likely they won't be able to deliver. And that prices will rise even further. How can you adapt to disruptions, even turn them into a benefit? Historically, pottery has been a shining star of resilience and independence because the materials were in the ground nearby. You cannot likely head out to the nearest hill with your wheelbarrow to get clay, but you can do something even better.

Rather than viewing these containers as full of specific brand-name clays, minerals and man-made powders, it is better to view them as full of materials that supply the physical properties and chemistries needed to make bodies, glazes, engobes, slips, etc. By characterizing your glazes and bodies, using an effective record-keeping system, you can not only adjust recipes to adapt to changing supplies, but even improve them in the process (adjusting glaze thermal expansion, temperature, surface, color, etc). Or, use materials native to your area. It is not rocket science; it is just work and gradual learning accompanied by organized record-keeping, good labelling and interpretation skills.

As potters, we learned that no one is affected by supply chain problems more than prepared glaze manufacturers; they have complex recipes that require complex supply chains. It wasn't just availability; product consistency was also affected. It is again time to think about DIY, to start learning how to weigh out the ingredients to make at least some of your own. Arm yourself with good base recipes that fit your clay bodies (without crazing or shivering). Add stains, opacifiers and variegators to the bases to make anything you want. Admittedly, ingredients in your recipes can also become unavailable! But DIY as about options. When you "understand" glaze ingredients and what each contributes to the recipe and oxide chemistry, you are equipped to go well beyond weathering material supply issues. You will improve recipes, not just adjust them, to accommodate alternative materials. It is not rocket science; it is just work accompanied by organized record-keeping and good labelling.

Make your own vibrating sieve

And process your own super-fine clays

Being more independent is now cool again. Actually, it is being forced upon us by necessity because of supply chain issues and skyrocketing prices of convenience glazes, bodies, engobes, etc. Independence involves using sieves. True, it is no problem for a potter or lab tech to manually coax a glaze slurry through a small 80# sieve. But real independence is about sieving in volume - clay bodies made from your own native clays. And doing it at up to 325 mesh. That requires a vibrating sieve. This one cost us less than $100 to make. Of course, a Tyler sieve (or similar) is needed, these can be purchased on Ebay or Amazon. And a vibration motor, some metal and hardware and a friend with metal fabrication tools. This demonstrates the utility of a vibrating sieve, the idea can be scaled to any size you need. As an example, oil well drilling sites here have to remove particulates from huge volumes of drilling mud and they do it on giant multi-level units.
