Every Isa Ceramics piece is handmade with love: shaped, glazed, and fired by hand in my studio in the Netherlands.
Because of this process, no two pieces will ever be exactly the same. Small variations in shape, size, or glaze are part of the charm and character of handmade ceramics.
This page explains what’s considered normal for handmade pieces, and when you might want to reach out to me if something doesn’t feel right.

How to care for your ceramics?
• All mugs are dishwasher and microwave safe, but handwashing is recommended for long-lasting beauty.
• Avoid extreme temperature changes (e.g., pouring boiling water into a cold mug).
• Let mugs cool down naturally after use before washing.
• Don’t use your piece in the oven or on direct heat.
