Well the terracotta you see above are out door hangers ( outdoor candles ) you can hang those terracotta diya ( as we call them in India ) with a jute thread - therefore the wick has to be thick, and sure the terracotta will not break, they are fired above 1000*C. And well all are handmade with the aid of molds. Wish you all can see my entire collection - but cant really post you my link as it might be understood as spamming :undecided or against forum rules
