Before you ask for a commission
What she makes
Things for a table or a shelf: sets of plates, jars, a vase for a particular window. No tiles, no sculpture, no replicas.
How long
Commissions go into the next kiln with a gap, which is usually six to ten weeks from yes.
What it costs
Roughly the sale price per piece, plus 20% for sets that have to match. A deposit of a third.
If it doesn't come out right
Glaze is chemistry and fire. If a piece fails she makes it again in the next kiln, and you pay nothing more.
