Marx Magic Mender for Fired and Unfired Ceramic / Pottery Repairs and Add-Ons

I used the product to repair a divot in a kiln shelf where glass had stuck to the shelf. I filled in the divot, allowed the material to dry, and sanded it smooth. I then fired the kiln to 1650 degrees to cure the filler. It appears to be working well. I kiln washed the repaired shelf and have done about five fuse firings with no visible degradation of the fill material or glass sticking problems.

I make ceramic dollhouse miniatures, vases, pitchers, plates, etc. I use low-fire clay and glazes. This mender works to hold handles, repair tiny greenware pieces that have broken, and even add a handle to an already fired piece! It is great! I have attached a 1/8 inch diameter greenware handle to a 1 inch tall pitcher! It takes holding the pieces together for about 30 seconds, then it is dried and will hold. I recommend this product.

I purchased this in an effort to save a cracked slumping mold for fused glass. I had very high expectations, as these molds are very costly. Instead of it working, the mold further cracked to several pieces, instead of the 2 I started with. I carefully followed the directions. Don't waste your money!

I cannot get this to work on a glass casting mold. It works for 1-2 firings and then the piece comes loose again. I have tried 4 times now.

Wish I didn't have to fire it!

Fixes chips in bisque and is often successful in patching breaks in green ware.

Works on small breaks but not very well on more substantive breaks.

The product performed well and as claimed. I used it to mend a bone dry teapot that I mishandled and broke.
