Importance of Recycling Clay in Pottery
Pottery recycling clay is a clever approach. It decreases waste and enables the reuse of materials that have not yet been fired. Consider all the unsuccessful pots or projects that didn’t meet your expectations.
Instead of discarding them, this “bone dry” or “leather-hard” clay can be recycled for practice, or even for crafting new art. This process is not only beneficial for your budget, but it also promotes environmental friendliness by minimizing what we discard.
It equally improves the performance of your clay. Reclaiming clay involves its re-mixing, which effectively disseminates the minute particles inside. This process makes the clay more flexible and less prone to break when you’re crafting something with it – either on a wheel or by hand construction.
And, don’t overlook the throwing water! That cloudy water left from clay work? It’s laden with valuable pieces of clay that can amplify the quality of recycled materials. Recycling scraps not only reduces how much waste artists generate but also improves their materials’ function.
Preparing Your Work Area for Clay Reclamation
Get the tools and materials you need for reclaiming clay – think plaster bats, pottery wheels, and basic pottery tools. Create a proper drying area where you can lay out your clay to dry before starting the reclamation process.
Gather necessary tools and materials
You’ll need a few things before you start reclaiming clay. Grab a bucket for the wet stuff and something to mix it with – think drill and paint mixer. You also need an 80 mesh glaze sieve to get rid of unwanted bits.
Don’t forget a long-handled scrub brush, plaster slab, and a big plastic tote – 38L Rubbermaid ones work great.
For drying out your clay, wooden blocks and plastic squeeze clamps come in handy. Also, an old bed sheet will be perfect for spreading the clay out.
Now that you have everything ready, let’s move on to setting up your workspace just right.
Pottery is as much about patience and prep as it is about art.
Set up a designated drying area
Choose a specific spot for drying clay. This makes the reclamation process smoother. A heavy-duty trash container with wheels helps collect clay scraps easily. For the drying area, use absorbent surfaces like plaster bats or wedging tables.
These materials pull moisture out of wet clay well.
Spread your clay thin on these surfaces to dry faster. Flip it now and then for even drying. This trick stops parts from staying wet while others dry up fast. Making a spot just for drying keeps your work organized and speeds things up, so you’re ready to start creating again sooner.
Sorting and Prepping Clay Scraps
When it’s time to process your clay scraps, start by removing any foreign materials and separating the clay by type and condition. This step prepares your clay for the next stages of reclamation without hindrance or contamination.

Submerging clay scraps in water
Once you’ve gathered your clay scraps, it’s time to immerse them in water. This process is called “slaking.” Whether your clay is dry or wet, place it in a container and cover it with water.
You’ll need to let the clay soak for some time so that it can absorb the water properly.
For quicker slaking, allow the clay to dry before submerging. Maintaining a layer of water on top of the clay during this process will aid in mixing later on. Remember to be patient as proper slaking takes some time – but it’s a crucial step towards reclaiming and recycling your clay for pottery projects!
Time required for proper slaking
After you’ve submerged the clay scraps in water, the process of slaking begins. The excess water needs to leave the clay mixture for proper consistency, which can take anywhere from one day to a whole week.
It’s crucial to monitor the firmness of the clay mix to determine when it reaches the right plasticity level. If your mixture is excessively runny, allow it to sit for a few days so that excess water can evaporate before using it.
This phase is significant because reclaimed clay requires this time frame for optimal reuse and workability in your pottery projects. As with all stages of reclaiming and recycling clay, patience and observation are key during the slaking period.
Drying the Slaked Clay
After slaking your clay, it’s time to dry it out. Spread the clay thinly and keep an eye on its moisture content.
