Re: Bottomless Molds - traditional slumping method?

The fact that they have no bottom means that yes they are vented. Air can escape between the mold and the shelf. If it will not hold water it will not hold air. R.

Re: Glass surface dulling

Like he said but you can try rinsing with distilled water after cleaning, never using windex and venting the kiln to 1100 f during the firing. Since it is an intermittant problem this might cure. R.

Re: Embossing float 10 mm glass

The devit was probably from burning out the binders in the fiber paper. To avoid that I vent the kiln up to 1100 f and usually hold there for 20 min or so. This hold just seems to make the glass happier. Venting is huge. R.

faux tempered glass

What to do when tempered glass is not tempered? The glass in the salon door of a new yacht I am working on has a crack across one corner. We buy only tempered glass for these boats.

Re: Embossing float 10 mm glass

Thank you Bert. Yesterday I run one sample in a small kiln and ,yes, I need go hotter. I'll try 1420 with 40 m hold. Why tin side down? A lot of sources recommend tin up to avoid devitrification. What do you mean that air side down will make it rough? Sorry for questions, but I will run my kiln tod...

Re: Carbon burn off and heating element damage

like they said there is an oxide coating formed on the element the first time it is fired. it stays there untill there is a reducing atmosphere in the kiln. then the next time the kiln is fired the oxide forms again. this can eventually wear the element thin. if you want to do some reducing stuff , ...

Re: Pocket Vase Disaster Using Stainless Drape Form

the fiber paper cushions the metal insert from the glass. it is soft and allows wiggle room for removing the form. yes stainless contracts more than glass on cool down but in reality it helps to have that cushion there. R.

You will also need to put more fiber around the metal insert so that the glass does not grab it on cool down.
