boric acid source

Recommended Posts

I've been reading that some guys use boric acid as a welding flux or as part of a flux mix.

I needed to edit my info, after a little research I realized I mispoke. The wood preservative I spoke of originally isn't the same. I'm glad I caught it in time.

Are you telling, or asking? If you want smaller quantities, several common roach poisons are 98%-99%% boric acid (and 1%-2% "inert ingredients"). Roach Prufe and Hot Shot Roach Killing Powder are two examples. You can buy them just about anywhere, and they're cheap.

www.rosemill.com In ct. Has boric acid technical grade in 5 10 and 15 pound containers for 23.50 to 64.00 USD plus shipping.

Cheaper if you go and pick it up. I have emailed them, they seem like good folks, but never actually needed 5lbs or more of boric acid at once. I use EZ weld, until it runs out, then Ill go to borax that I use for laundry.

Best of luck,
