Ganister

07/25/2013 11:52 AM

Hi all Some 40 years ago I worked for some time as a furnace man in a small iron foundry and each day we had to make good the inside of the furnace from the previouse days blow using fire bricks and Ganisiter.

My question is about this ganister. It apeared ti be a mixture of pea gravel and clay but i am not too sure after all these years.I am told that this is no longer available and as been replaced by other castable refractory materials but i would like to know what the mix realy was and if i can obtain the constituants to mix it myself for a home project

can anyone help please

"A ganister is hard, fine-grained quartzose sandstone, or orthoquartzite,[1] used in the manufacture of silica brick typically used to line furnaces. Ganisters are cemented with secondary silica and typically have a characteristic splintery fracture.

Cornish miners originally coined this term for hard, chemically and physically inert silica-cemented quartzose sandstones, commonly, but not always found as seatearths within English Carboniferous coal measures. This term is now used for similar quartzose sandstones found typically as seatearths in the Carboniferous coal measures of Nova Scotia, the United States, and the Triassic coal-bearing strata of the Sydney Basin in Australia.[2][3][4]"

Here is a picture of the chute I used to back up to to receive a load of Ganister to transport to glass and steel works in Cheshire and Lancashire, U.K. http://www.yourlocalweb.co.uk/cheshire/congleton-edge/pictures/4060325-ganister-works/ Sorry, I don't have a clue what the chemical composition was. I do remember if I took bumpy roads the water would settle out and leak from the truck box and what remained wouldn't slide out at the destination, and if I travelled too slowly it would dry out and again, I would find myself shovelling out almost 10 tons of the stuff! It was gritty in texture but I can't ever recall it having pea gravel in it. The plant in the picture was adjacent to a large silica sand deposit. The sand from which was very similar to the white silica sand found on Black island in Lake Winnipeg, Manitoba, Canada. I was told that there were only three or four good deposits in the world to rival the quality of those two deposits.

Hi rcdesign,

A recommendation:

A clickable link is easily made by copying the URL (in your case http://www.yourlocalweb.co.uk/cheshire/congleton-edge/pictures/4060325-ganister-works/). If I then select this and click on the icon in the editor. A dialog box will appear and you will see the URL in both the Text and URL boxes. Click OK.

I have made one here to the very web site you have indexed (above, highlighted in blue and underlined!).

Click it and make sure it works!

Thanks Mikerho. I have been trying to figure out how to embed links for some time now and never managed it. Could be because the "Link" icon you displayed does not show up in Safari and if I use the html string on a web page I can add text such as "Click Here for a good time" and have it go to a new page. When I try this in CR4 and go to preview the entry, the string disappears totally or the URL stays, as in the way it was in my previous comment. However I really do appreciate you pointing this out. Thanks for the help. Ian at rcdesign@shaw.ca

Many thanks. Many times I tried following the example below but only just tried placing the "button" between the square brackets. Not what I am used to in html. I appreciate you comment. I made me try harder.
