where to buy sodium silicate-liquid glass?

[Tater Pickens]

Where do you guys buy the liquid glass(sodium silicate) to seal in the over shot card on your brass shot shells?

Thanks,

Please pardon my intrusion.....

Isn't sodium-silicate the main ingredient in the stop leak products sold in the automotive section for head-block-radiator leaks....

Try the auto parts store or even the Home & Farm stores like Murdock's - Big R - Bomgaars .....

I got a four ounce bottle at Gemmel's Pharmacy.  They are also my source for nitric acid for etching brass.

Most pharmacies will carrt it or get it in for you . Ask for 'waterglass' they may know it by tha name.

Thanks gentlemen. I found some at a local pharmacy. Right pricey stuff.

I've heard of it used as a block sealant in automobiles so can't imagine what pharmaceutical use there may be for the stuff but my local auto supply didn't have any

ya don't need a lot to make the seal. I usually seat the over shot wad then ppour a very small amount , just enough to cover the card a bit and let it stand till it hardens.
Enjoy

I have a new sealed gallon jug that I saved from work when they were going to throw it out.
If it would keep I'd divide it out since a gallon is more than a life time supply. But have heard that once air gets to it it won't last long.

also I found if it stands for any lenght of time , some of the compound settles to the bottom . Every  onec in a while I turn the bottle to keep it suspended,

I've also seen where re loaders use Elmer's wood glue in place of water glass. Not period correct but it will work.

Skylighter carries it, and it can usually be found on ebay as well for about $20 +-  a quart.

Sometimes the powder form is available on ebay... a pound of it makes about a quart to 1/2 gallon or so when mixed with water depending on how thick you prefer it.  The powder version is usually cheaper when shipping is considered cuz you aren't paying to ship water.

I've got about 15oz of a 16oz bottle left. If you're willing to pay shipping, it's yours. Don't use it anymore.

PS - I found my bottle on eBay.
