For the benefit of the lazy:

Iron is added to the raw material that makes glass (mostly sand and recycled glass shards) to give color to the glass so that it absorbs heat better. This causes the raw material to liquify quicker so they can make more glass per day. This is also why low iron glass costs more. If your energy costs per day are the same but you are making 30% less glass you have to charge more. The amount of iron (2 lbs per 1000 tons) is negligible and has no effect on the hardness of the glass. Low iron glass does not scratch any easier than regular glass. What it does do is show scratches better. This is because the optical clarity is so much higher that very tiny scratches that would go unnoticed on regular green glass stand out. Consequently you have to be more careful when cleaning the glass.

I think it sounds v. logical to me :)

And if he's right, those building pico tanks would be better off paying for acrylic for clarity? or does he mean normal glass would be equally as clear?

I don't think iron is purposely added to the raw materials for normal glass as what the person posted. Iron (II) oxide is present in the raw material for glass making, mainly silica sand. Crystal glass is made from silica products with minimal iron present.

Comy, the poster said the 2 types of glass at 1/4 inch (6mm) and below show a negligible difference in optical clarity, so I guess he means you're better off using normal glass.

imo,go for clear crystal glass some may understand it as starphire glass. locally not much maker can get their hands on this glass nowadays. not easy to get in sg.

as for low iron glass. am a user myself and from a low iron : crystal clear glass/starphire - see a big difference in clarity. as for low iron: normal glass - dont waste your $.

@_@ Blur liao... So what I understand from your statement is that Crystal Clear = Starphire. Low iron is different from Crystal Clear or Starphire?

Sorry, very drugged up at home, recovering from gastric flu since yesterday lol.

yes, heard that crystal glass is very diff from the normal low iron glass but its quite difficult to obtain that kind of glass in sg. info from a tank maker. nvr confirm the source. i can see the diff in the low iron glass tank when i compare the glass panel.

yes the thicker the better... but anyrhing above 12 mm is very expensive.

my 3.5ft low iron glass tank is price around 500 for 3 sides. well ofcoz a normal float tank is cheaper. if u got the $ try it. vincent why not do 2 panel then report the diff. :P

I am just an average FR (fish reefing) writer. If you like my FRs, please upz my points.

Hi there, been very informative reading the postings here. I was wondering does crystal glass only comes in 100% colorless hue? Cos I am taking over a tank set, and the owner told me the front panel is made of Crystal glass, and I noticed it has a slight blue hue to it, is tt also considered crystal glass?

Also I was told some crystal glass tend to have a light bluish/golden hue to it, are these also considered crystal glass? :thanks:

a picture speaks a thousand words.. went to find my tankmaker today and requested for samples of the glass that will be used..

12mm normal glass is really darker than i expected. <_<

12mm low-iron is really really clear. :shock:

haha ya i also think mai tu liao.. hahaha.. after seeing the glass comparison in person, really no horse run..

Nice... So which tankmaker did you go to?

went back to my old tankmaker, Kwong Lin Framemaker at kelantan street.. very gd pricing.. :) same pricing for lowiron as the lobang u recommended..

actually there isnt any starphire glass.we all know that starphire is a kind of gem stone and the price it can command per stone. so imagine having it into a glass panel. the price will be great!

the debate of glass panel material which involve "starphire"/crystal glass,low iron glass,normal glass goes on and on everywheer around the world.

if u do a detail google search less wikipedia(not official) you will find mix comments about each review.

end of the day, i guess goes all down to $ vs quality and perhaps on how long you will own it.

say e.g 2ft cube tank $5k for plexi glass but use for 1year vs crystal glass $2k use for 1year. is the difference in clarity that great? :)

the clear glass looks more then jus an low iron glass.

perhaps there is even different grades of low iron glass.
