Buying handmade work is less about spotting problems than understanding what is being offered — which is a conversation most makers are glad to have.
The questions
"Who made this, and where?" Made by the seller, made in their workshop, or bought from a maker. All legitimate, and the answer changes what you are buying.
"Is this the exact piece, or one like it?" For handmade work there is a real difference between this one and one like this. Made-to-order work will vary, and that is normal — but know which you are bidding on before the clock runs out.
"Is that intentional?" The best question in the category. Slight asymmetry, tool marks and glaze variation are evidence of the hand. A chip, a crack or a failed finish is a fault. Ask rather than guess.
"How long did it take?" Not a challenge — most makers enjoy answering, and the answer is half of why handmade work costs what it does.
"Is it food-safe, watertight, outdoor-safe?" For anything functional these are the facts that decide whether you can use it.
"How should I care for it, and will it change with use?" Many finishes have rules, and many change on purpose.
What protection covers
A piece that arrives damaged, a different piece, a different material, or a repair not mentioned: seven days from delivery. Natural variation that was described as variation is not a fault.
Questions people ask
Can I ask for something to be made for me?
Often yes. That is a made-to-order arrangement and works differently from an auction.
Why is handmade work expensive?
You are buying hours. Ask how many.
What if the colour looks different on screen?
Ask for it in daylight during the show.
