    Care Instructions
    • Wash with mild soap and warm water after each use.
    • Dry immediately with a soft cloth to help prevent water spotting.
    • Water spots can occur due to natural trace minerals found in tap water.
    • Over time, copper may develop a soft matte patina — a natural finish many people appreciate.
    • If you prefer the original bright shine, it can be easily restored with a quick copper polish.
    • Copper is designed to age beautifully — maintain the shine or embrace the patina.

    Shipping details

    What is processing time?

    Processing time is the period between placing your order and the package being handed to the shipping carrier.

    Most orders are processed within 2–5 business days, Monday–Friday excluding holidays.

    During this time, your item may be picked, prepared, produced, finished, assembled, personalized, packed, or otherwise made ready for shipment.

    Shipping time does not include processing time. Carrier transit begins after processing is complete and the package has been accepted for shipment.

    Where does my order ship from?

    My American Goods® uses a hybrid fulfillment model.

    • Some products are stocked and shipped directly by My American Goods.
    • Other products ship directly from the independent American brand or maker.

    This allows us to offer a much broader selection of American-made products while supporting the independent businesses that make them.

    Why might my order arrive in multiple packages?

    Products in the same order may ship from different fulfillment locations.

    As a result, items may:

    • Ship on different days
    • Arrive in separate packages
    • Have different tracking numbers
    • Use different shipping carriers or services

    Receiving one package does not necessarily mean the rest of your order is missing.

    How are shipping rates calculated?

    Because products may ship from different makers and fulfillment locations, shipping rates can vary by product or brand.

    • Some products or brands qualify for free shipping above a specific threshold.
    • Other products may use flat-rate or carrier-calculated shipping.
    • Products shipping from separate locations may generate separate shipping charges.

    The applicable shipping cost is shown before your order is completed.

    When will I receive tracking?

    Tracking information is emailed once your item has been prepared and shipped.

    For handmade, made-to-order, pre-order, or specialty products, tracking may not be available until the applicable preparation or production period is complete.

    If the expected processing period for your item has passed and you have not received a shipping update, please contact us.

    Carrier delays & missing packages

    After a package has been accepted by USPS, UPS, FedEx, or another shipping carrier, transit may be affected by weather, holidays, peak-volume periods, transportation disruptions, or other carrier conditions outside our control.

    Shipping and delivery timelines are estimates unless expressly stated otherwise.

    If tracking shows Delivered but you cannot locate the package, check:

    • Household members
    • Neighbors
    • Porches, side doors, garages, and other delivery areas
    • Parcel lockers or building mailrooms

    Carrier scans can occasionally appear shortly before final delivery. If the package still cannot be located, we can assist with a carrier investigation.

    Shipping address accuracy

    Please review your shipping address carefully before completing your order.

    Customers are responsible for providing a complete and accurate delivery address.

    Packages returned because of an incorrect, incomplete, or undeliverable address may require additional shipping charges before they can be sent again.

    Where does My American Goods ship?

    My American Goods® currently ships within the United States only.

    The Story behind Sertodo

    Sertodo Copper was founded by Jonathan Beall, whose journey began in 1997 selling handcrafted copper throughout the United States from the back of his truck, affectionately named El Macho. His path led him to Santa Clara del Cobre in the Sierra Madre Occidental of Michoacán, where he apprenticed for two years under Maestro Maximo and Maestro Chema, learning a copper-working tradition that spans more than 1,000 years.

    After completing his apprenticeship, Jonathan partnered with Maximo’s eldest son, Martin, to build a workshop rooted in respect for craft, family, and heritage. What started as a simple dirt-floor, two-person space has grown into a thriving copper studio — but the commitment to traditional craftsmanship, integrity, and community remains unchanged.

    We love Sertodo because it represents true artisan lineage: heritage techniques preserved through apprenticeship, relationships built on trust, and copperware made with purpose and pride — exactly the kind of story and substance that belongs at My American Goods.

    Sertodo FAQs

    What products does Sertodo offer?

    Sertodo makes hand-forged copperware and kitchen tools, including copper pots and pans, hammers, charcuterie tools, chef accessories, and durable cookware essentials.

    Are Sertodo products made in the USA?

    Sertodo copper goods are designed and finished in Austin, Texas, and handcrafted by skilled artisans in both the USA and Mexico using traditional copperworking techniques.

    This approach allows Sertodo to preserve centuries-old craftsmanship while maintaining the quality and design standards rooted in their Texas-based operation.

    Every piece is made from 100% recycled copper and crafted in small batches for lasting durability and character.

    Why cook with copper?

    Copper provides superior heat conductivity and precise temperature control, making it ideal for professional chefs and serious home cooks.

    Is Sertodo cookware lined?

    Many Sertodo cookware pieces are tin-lined for safe cooking performance, while some items are pure copper for bar or decorative use. Always follow product specifications.

    How do I care for copper cookware?

    Hand wash only. To maintain shine, polish occasionally. Natural patina over time is normal and does not affect performance.

    Is Sertodo copperware good for gifting?

    Yes — Sertodo pieces are heirloom-quality gifts for weddings, housewarmings, chefs, and cocktail enthusiasts who value craftsmanship and longevity.
