Success. Thanks for the support

Brad, I’ve just emailed three photos of a smashed, glass canoe I made many years ago. The owner would like it repaired. Is it possible to refuse all the pieces onto a clear sheet? Will I need to help the pieces join by boxing it in or going into the kiln with a wooden tool when hot and fusing? Anyon...

Thanks guys. I went to 820 C before seeing the replies. The blue cement has turned white and all seems good. I now have a new, flat, bigger shelf on top of the old one.
Kevin, what is crystobalite?

I’ve rigidized, fired and cemented a fibreboard in an effort to make a new kiln shelf for my 2417 Evenheat. Does anyone know what temp Celsius I need to fire the cemented fibreboard? I used QF 180 blue as the cement.
Thanks in anticipation

I've just teadJim Burchet's post about glass stuck to s.s ring mould.
So if I reheat the to around 300 how do I get it out without thermal shock?

A slumped stringer bowl is firmly stuck in its stainless steel sink mould. I don't think the glass is stuck to the steel. I think it's pinched by the contracted steel. The mould was sprayed with release using an air gun, four applications. The stringer bowl is four perpendicular layers of 1mm clear ...

Also has anyone experienced the spread of the reaction outside of the 1015 that bullseye warns about in their notes on 1015?

Does anyone know of a food safe adhesive for glass and/or ceramics?
Have asked Loctite who replied that they don't have one in my area (Australia)

marian the cement i'm using is QF-180 by Unifrax its a tedious process but worthwhile i'm still using a 25mm thick shelf 5 years after i treated it in the same manner the process i use is detailed in bullseye's technotes 6 i'm using 6mm this time because its the thinness that will allow me to use th...

thanks for your replies chaim and bert
