Votives are more of normal candles with a lower melting point. The wax gets accumulated on burning, to collect which you need specific votive candle holder. The wax melts, liquefies and gets fully consumed by the flaming wick at the surface of the holder to keep the surrounding area clean from any mess.
As the votives melt onto the surface, one needs to be very careful while shopping for the holders. It should either have tapered material or bowl shape to ensure that the melted wax burns away by pooling towards the center. A minor mistake in the selection of candle stand can create a huge mess of unused wax to be cleaned up after the party.
