How to make glass bottle moulds for breakaway bottles.

Hi, need to ask for advice on the procedures, materials and tools to make bottle moulds for the fabrication of breakaway bottles. Thanks!

Do they actually have to be hollow?

ooh! you could cut a plastic bottle in half and then pour some of the fake glass in it ...

Well, being hollow would make them easier to break, no?

Yes, i need them to be hollow. As real as it can get while still able to DIY. Thanks.

thats why you should just cut a plastic bottle in half, pour in a thin layer on both halfs then when its dry or something pop them out then seal them together. i havnt tried it so i dunno if it works....

Compicated idea so you get a daigram. Make an outer bottle mould, the size of the bottle you want. Also make an inner plug about 1/4 inch smaller. Suspend the inner inside the outer, then fill with liquid sugar glass. When hard remove both moulds, then attach a sugar glass disc to the bottom, completing the bottle.

So the moulds wld hafta be what kind of materials? Clay?

[UFProductions]

The outer one could be a real bottle with the bottom cut off, the inner one could be anything, a smaller bottle, wood, or clay like you said.

Make a two part plaster mould of your bottle, or rubber if you can afford it and mix up a batch of sugar glass. Fill the mould and let it set up for a few moments. Pour the excess sugar glass mixture out and let the mould cool. Open it and voila! Hollow breakable prop.
