Hi Stella thanks for the reply. Yes it's a Hurricane lantern & I know normally they are made in a mould but I'm making them from a poured out slab as we want to embed all manner of things like stained glass, marbles, shells etc & I would have a greater freedom of what, where & how I make them this way & have an old mitre box so I can cut the corners to 45 degrees but they will need gluing.
