Majolica-style Vase

Unmarked vase. Looks slip moulded and hand painted. Could be modern. Unmarked

The design is very Japanese as is the lack of a mark but that base. I am not sure I have seen any Japanese items with a base like that. The design would indicate is comes from the period 1870 - 1920. Should be easy to prove because if it has been around that length of time it will have tiny scratch marks on the base from a 100 years of just general ware. But I can't see any wear in the pictures and although the colours are nice the vase does have a wonky rim and its thickly formed. That kind of indicates to me its Asian but not Japanese.

My best guess then is modern due to lack of wear and from China. It could also be from Thailand, I think it's 50/50 chance of both.

I think you're right about it being modern Thailand. Reminds me of similar slip-trailed cups and tiles.
