Diz Posted August 24, 2017 Report Share Posted August 24, 2017 Yes - we want the cups to break. I have a request from our local theater group for cups that will break when a toast is made. Haven't had this request before so I would like help to do it the correct way the first time (as they need them within 2 weeks). My first thought is to throw them very thin with my cone 5 clay and have both firings just go to bisque and use cone 05 glazes. Your opinions on this method or better ways to do this would be appreciated. I also have cone 10 clay available to use. Thanks! Diz Link to comment Share on other sites More sharing options...
Tyler Miller Posted August 24, 2017 Report Share Posted August 24, 2017 I was asked to do this two years ago when I fell in with some theatre people. Ceramic is unsuitable for breakaway props. Industry uses a thin acrylic for this. One, because they want non-sharp edges, two because they want something light that won't injure actors or, worse, audience members. The glaze can be sharp, and clay is heavy. Picture Stanley Kowalski's plate smashing and bottle breaking with real ceramic--the actors would need safety glasses Proper breakaway props have nearly no mass, very light. Also, very cheap. Like, a six pack of beer bottles was around $20 USD? Link to comment Share on other sites More sharing options...
neilestrick Posted August 24, 2017 Report Share Posted August 24, 2017 I agree with Tyler. Breaking real ceramic cups is not safe. Way too many sharp edges. Link to comment Share on other sites More sharing options...
tricetra Posted August 24, 2017 Report Share Posted August 24, 2017 If they just want some for show eg not to hold any liquid, then why not use dried green ware and paint with acrylic paints that way there is no sharp edges ;-) just an idea. xx Link to comment Share on other sites More sharing options...
bciskepottery Posted August 25, 2017 Report Share Posted August 25, 2017 A friend used bisque ware for breakable items in a theater production. I understand in some countries, small shot-size bisqued cups are used in place of disposable plastic, etc. by some street vendors -- drink the tea and then smash the cup on the ground back into clay.

Diz Posted August 25, 2017 Author Report Share Posted August 25, 2017 yes , Tyler's comment makes perfect sense and I will pass it on. Thanks for the input - safety first. I appreciate the comments and help. Link to comment Share on other sites More sharing options...
Mark C. Posted August 25, 2017 Report Share Posted August 25, 2017 Bake it out of cookie dough like a fortune cookie-will break easy Link to comment Share on other sites More sharing options...
Denice Posted August 25, 2017 Report Share Posted August 25, 2017 Maybe you could do a low fire bisque on the Cone 10 porcelain, it would be nice and white and smash easily. Do you have a test kiln and time to test some ideas. Denice Link to comment Share on other sites More sharing options...
Stone Spiral Posted August 27, 2017 Report Share Posted August 27, 2017 I like the greenware idea, however it doesn't give the same satisfying SMASH sound.. hehehe(Does anyone else smash their cracked or chipped bisque with gusto??) Link to comment Share on other sites More sharing options...

I just love that phrasing, "Fell in with some theatre people"... "That Tyler, he was on a good path, until he got mixed up with those performing arts folks..." In regards to the question, sugar glass is what they usually use for any prop glass (bottles, windows, etc.) It breaks like glass, with little chance of injury, and the ability to snack on the resulting pieces.
