Although this pieces is made from vitrified porcelaneous stoneware and the interior is fully glazed, please be aware that over time moisture *can* seep through the clay body and damage fine wood finishes. I learned this the hard way as a young bride excited to use a locally prominent potter's vase on my inlaw's mahogany sideboard. I use a small coaster or saucer if a piece is on display for more than a few hours!
