cichfanatic Posted February 23, 2007 Report Share Posted February 23, 2007 Can someone give me good advice? Has anyone here used toughened glass before and had problems I’m planning a tank 1800x700x700 and have a few options on type of glass to use Either 12mm annealed or 10 or 12 mm toughened I’m building this tank to sit in tank stand so bottom of tank will be fully supported I have built large tanks for myself in the past but not as wide and high as this one out of annealed Anyway that’s why I’m thinking about using toughened glass I also realize that toughened is about 5 times stronger than annealed on the faces but can shatter with just a tap to its edge Thinking should I go for toughened of using alum protective corner extrusion to protect all the edges Bottom glass panel is going to be drilled with holes for sump and filter inlets and outlets So any feed back much appreciated Quote Link to comment Share on other sites More sharing options...
smidey Posted February 23, 2007 Report Share Posted February 23, 2007 I dont know a great deal about glass but have had a bit of experience with it. Toughened is quite strong but very brittle on the edges & it will also curve if forced. It will have to be drilled before being toughened. Think it may be better to discuss with a glazier first.

quack Posted February 23, 2007 Report Share Posted February 23, 2007 yeah 12mm with good bracing will be sweet, ive got 10mm on my 1700x700wx600h and its sweet Quote Link to comment Share on other sites More sharing options...
cichfanatic Posted February 23, 2007 Author Report Share Posted February 23, 2007 Hey thanks for the feed back Looks like 12mm annealed is the way to go with good bracing Still has anyone out there used toughened glass and had it explode on them? What a disaster that would be for fish and house Quote Link to comment Share on other sites More sharing options...
alanmin4304 Posted February 23, 2007 Report Share Posted February 23, 2007 I made a tank out of 3 doors from a bank in 12mm toughened glass and I gave it to a friend 20 years ago and it is still going OK. Quote Link to comment Share on other sites More sharing options...
TM Posted February 24, 2007 Report Share Posted February 24, 2007 Is the extra cost worth it? Have you checked up on toughend glass prices? Quote Link to comment Share on other sites More sharing options...
quack Posted February 24, 2007 Report Share Posted February 24, 2007 Have you checked up on toughend glass prices? yeah they are steep!! Quote Link to comment Share on other sites More sharing options...
alanmin4304 Posted February 24, 2007 Report Share Posted February 24, 2007 Mine cost $10.00 at an auction-- Worth checking second hand stuff Quote Link to comment Share on other sites More sharing options...
cichfanatic Posted February 24, 2007 Author Report Share Posted February 24, 2007 The cost isn't an issue as I have a few friends in the glass industry So can get the glass at a good price I used to be a glazier probably 7 years ago now was in the glass industry for 20 years so have used toughened glass for many applications but never for a fish tank. A little bit apprehensive as I know sometimes it can shatter without warning and any apparent reason Just interested to see if anyone has used it and how well the glass stayed together Seems to me cheaper option 12mm annealed is the way to go Thanks for all your feedback Quote Link to comment Share on other sites More sharing options...
quack Posted February 24, 2007 Report Share Posted February 24, 2007 i am also in the glass industry, and the price of toughened is far higher than the price of normal float glass. unless you can get it secound hand like alanmin4304 said then its baiscly out of the question as far as the price goes. off the top of my head i think its 2-3x the price as normal Quote Link to comment Share on other sites More sharing options...

You wanted good advice. Saying one is heaps dearer is good advice.

alanmin4304 Posted February 25, 2007 Report Share Posted February 25, 2007 Can you drill toughened glass and what would be the advantage of toughened? I built a tank in a cabinet for a restaurant and made the front from laminated glass in case some drunken idiot tried to break it in which case it would have leaked rather than explode like toughened would. The place went broke before it opened and it is now in my lounge. Quote Link to comment Share on other sites More sharing options...

quack Posted February 26, 2007 Report Share Posted February 26, 2007 once the glass is toughened then thats it. the only thing you can do is maybe sand about 5-10mm off each edge and even thats doogey. Quote Link to comment Share on other sites More sharing options...
