Frostmere: Provenance Research & E-Commerce

The Concept

Frostmere is a history-inspired e-commerce brand I built from scratch. Every item listed comes with original provenance research, tracing objects back to their makers, their era, and the human stories behind them. It operates as a DBA under my LLC, Aspen Groves Studio.
Higher-value pieces with deeper stories go on Frostmere. Smaller finds live on eBay under the same business umbrella.

How I Source

It starts in person. I walk into a local shop, scan the shelves, and look for anything that sparks curiosity or awe. Phone in hand, I photograph the item on the spot and run it through Google reverse image search or send it to an AI assistant I've configured to return the details I care about: what it is, where it came from, the basics, and a quick opinion on whether it's a smart buy, a potential loss, or not worth the time.
That opinion is just one input. I make the final call myself. I'm very aware I don't know everything, and I'm learning as I go. Sourcing other perspectives keeps my mind open.

The Research Process

Once I have the initial identification, I start digging.
Marks, signatures, and language barriers. I photograph the bottom of every piece. Sometimes it's a clear brand stamp. Sometimes it's a hand-painted signature in Japanese or Chinese that I can't read, applied 70 years ago by someone whose name never made it into a database. AI helps me decode those. A lot of times it's not even a brand; it's a single artist's mark on a one-of-a-kind piece.
Narrowing it down. Say I've got a glass cup with a flower design. I search "1970s glass cup with flower" on Google or eBay. The AI helps me pin down the year range, the type of flower, and whether that design had its own production name (the way Corningware had "Spice of Life" or "Cornflower"). I'll refine: "70s glass cup with Lilac, etched." If it's a set, I note that. If the manufacturer released a different design every year from '71 to '76, I scroll through each one until I've matched it.
Going deeper. Sometimes the item itself doesn't have much of a story. But the maker always does. Who manufactured it? What was happening in that region at the time? What was the world like then? Who owned the company? Is it still around? Answer all of those and you'll find a story. It's kind of endless.
Art and paintings. If I find a painting with a signature, I photograph the signature (especially if I can't read it) and search for matches. I can usually identify the artist. Then I research their body of work. To determine if it's an original, reproduction, or reprint, I inspect the surface up close. I've been painting with acrylics and oils since I was a kid, so I can usually tell. Even if it's sealed with spray, you can feel the difference.
Negotiation. If my quick in-store research shows the shop's price is too high relative to market value, I negotiate. They've never said no. I go there a lot.

The Business

Frostmere is where the more valuable, story-rich pieces live. Items under $20 or without a deep provenance angle stay on eBay. Every Frostmere listing includes the research: what the item is, who made it, when, where, and why it matters. The goal is to sell objects people want to keep, not just own.
