Re: Problems with WAFERS

A 1/8" thick layer of clear powder on top of your colour design helps retain wafer size because of the extra volume. It also helps me determine when the first wafer firing is done... by watching the firing and seeing the underneath colours become visible as the clear top powder melts it helps m...

Re: large kiln firing

I suggest your 9999 drop from fuse temp should be stopped at 1000F not 950F... you then move down slower as you are entering the anneal zone (80F dph to 950F) hold for anneal.. then 80F dph down to 700F then 125F dph to room temp before opening.

Re: Fill in possible gaps?

You would be better off to do a small overlap where the pieces come together.

Re: sumping large 9mm piece over stainess steel

What a bummer! I am always in favour of moving thru the anneal zone slower, eg: instead of your AFAP (full) to 900F.... I drop AFAP (full) to 1000F, then 80F/hr to 900, then hold for anneal (5hrs seems excessive for 10mm) then 60F/hr to 700F, then 100F/hr to 500, then 125F/hr to 250F, then off and d...

Re: DRAWING ON THE kiln-washed SHELF

I have been using a powder mixture containing AH in my kilns for over 20yrs. I have to scoop it up off kiln floor regularly after it spills over the kiln shelf. I'm sure a small amount has found it's way (dusting) onto the elements over time. The kilns 20yrs and 13 yrs old have shown no ill effects....

Re: DRAWING ON THE kiln-washed SHELF

I know wafers always shrink .. I misread your message and thought you meant the dry kilnwash was shrinking.( which of course it doesn't)..... I find with glass wafers you can control/reduce shrinkage by closely monitoring and shut down and crash cool as soon as light fusing occurs.

Re: DRAWING ON THE kiln-washed SHELF

I use dry powder on kilnshelf for texture etc. often... I have not experienced any shrinkage when fired. Powder of course is reusable.

Re: Satin look fire polishing

I hesitate to give you an exact temp. because it depends on a few things: First what glass? BE, 96, or other..... Second.. what colour?.. black glass will go past the satin stage and start to shine while white glass is just nicely satin...(other colours respond variously as well).. Third how long to...

I paid over $100. 10 years ago.. It was a good purchase then and it's still a good purchase now! Carbide cutter with bearings is the way to go! You are paying for Quality and dependability. :D

Clear Shield Gel

I am interested in opinions on using the following product on Gallery quality work. In it's new cat. Bullseye is selling Clear Shield Gel. They promote its use "where firepolishing isn't practical. Ideal for glass that has been sanblasted or coldworked". They go on to state it "adds l...

Re: A triptych

I often agree with some artists opinions that naming their work takes some of the "challenge/mystery" away from the piece. When the viewer is left to interpret the artwork without the artists prompt (title) it adds sometimes many unexpected layers to the work. I would not presume to know y...

Re: Silberschnitt circle cutter question

The carbide keeps it edge forever... ball bearings make this a smooth, excellent choice. I've used this to cut 12" to 24" circles for years. It's pricey but worth it.
