This sodium silicate solution helped me restore a ceramic, flame guard (for a gas torch) that had broken into five, irregular pieces. I painted the solution onto the broken edges of the ceramic pieces, assembled them back into a cylindrical shape, and used a tiny rubber band to "clamp" the fragments together.

In 30 minutes, the solution had set into a hard, clear, mineral "glass." I could remove the rubber band "clamp" and the pieces of ceramic held together for handling without any additional support. I used more solution to fill some small gaps where chips of the original ceramic were missing.

Per the instructions, I let the solution plus joined and patched pieces cure for 24 hours. Then, I used diamond files to remove the excess, hardened solution, and to shape the reconstructed areas. I was surprised at how hard the "cured" solution was, and how well it resisted abrasion from the diamond files.

The reassembled and restored, flame guard was even stronger than before. I tapped on it with a small, brass hammer, to seat it into the torch nozzle, and it did not break apart. It has withstood the high heat from the blue flame of the gas jet without disintegrating.

I am really impressed with this product. Its bonding strength and heat resistance on ceramic components is spectacular.

P.S. I did not experience any fumes from this product, and it dilutes and cleans away well with water. Do be careful not to let it into your eyes or mouth, or to have prolonged skin contact, as the solution is a strong base (alkaline) that is caustic to soft tissues.

UPDATE 05/08/2022:

The cured sodium silicate easily sustains under heat from a blue flame, which is between 2000 - 3000 deg. F. However, unless sealed with a silicone or other, water-resistant coating or film, it will readily dissolve in water or upon contact with it.

Also, the sodium silicate conducts electricity, and anything that is coated or permeated with it will not be insulated against electrical current.

This is an EXCELLENT product! If you do your own maintenance or commercial maintenance, this is a good product to have around for ceramic wool

Exactly what I was looking for to glue agate and petrified wood end cuts to 2x4s for my rock saw. I wasn't sure it was going to work, but after applying and sitting for at least 24 hours I put the wood with an agate on the end and cut 3 more slices off it! A bit pricey, but I did get more cuts I could use. I dropped 1 star due to price.

I bought this for my lint trap. The fuzzy strip came unattached and this adhesive worked great to attach it back. I've run my dryer a lot and the adhesive has held.

This is a good product. It has many uses. It was not useful on the project I originally intended it for. My mistake! But it has been good for many other applications, it turned out to be a good value.
