A pottery evening is physical work done seated: wedging clay, centering on the wheel, and holding a posture for an hour at a time in a warm, well-lit studio. The work dries the hands — clay absorbs water from the skin — and the studio's warm air plus the concentration of the craft push fluid loss past the point anyone notices. The measured rule is the water bottle out of the tote and onto the worktable: a drink at each stage change (wedging, throwing, trimming, glazing) turns the class's natural rhythm into the hydration schedule. The studio's tea-and-pastry break is the evening's treat, not the fluid line.
| Food | Oxalate (mg) | Serving | Rating |
|---|---|---|---|
| Water, still | 0 mg | 1 glass | Safe |
| Tea, black, brewed | 5 mg | 1 cup | Safe |
| Chocolate chip cookie | 12 mg | 1 medium | Caution |
| Banana bread, one slice | 8 mg | 1 slice | Caution |
| Apple, fresh | 2 mg | 1 medium | Safe |
The treat counter is the oxalate note of the evening: a chocolate chip cookie measures around 12 mg and banana bread near 8 mg — Caution range, mostly from the chocolate and the portion pattern rather than any single ingredient. Tea measures about 5 mg per cup, and one cup is comfortable. The measured habit is water as the working drink through both hours, one treat from the counter, and an apple in the tote for the drive home instead of a second pastry.
Three habits cover most of the upside. Bottle on the table, not in the bag — the class's stage changes are the drink cues, and two hours goes by faster than the fluid math suggests. Keep the treat line at one: the cookie or the banana bread, measured as a portion, not a sequence. And carry the apple — the drive home is when the evening's missed fluids usually get noticed, and the fruit plus water makes the ride part of the plan.
