Re: Crack on slump... Help?

First-- 1350 will not give you a "full fuse" Second-- I would pay more attention to the "anneal zone" slow down eg: 80dph from 1100 thru to anneal at 950 (45 min.) then 80dph to 800. then ramp down conservatively to 100. AFAP from fuse to anneal is not a good schedule. I don't th...

Re: gasket material

I've been opening and closing Brick lids on Brick wall kilns (some as big as 30"x 45") for 30 years.. Never felt the need for a gasket material.

Question for Brad.. Around 10 years ago I visited your studio/store in NC and I purchased over a dozen sunshine enamels. I am just now trying them out.. I have a good range of colours .. but it seems I chose "mixing flux" thinking it was white. This will limit my mixing pastels.. What is &...

Re: bottom heat kiln.

someone once made a wise statement: Glass needs to "see" the heat.. while pottery only needs to "feel" it! That is why elements in glass kiln roof and no multiple shelf layers when firing :) . Don

Re: bottom heat kiln.

I've been firing glass (large and small) going on 30yrs. Always with top elements and a few side ones.. I can think of numerous reasons to not want bottom elements. I suggest you reconsider!

Re: FIRE POLISHING

If the piece is the size of a fist then the firing schedule would have to be quite long and controlled to avoid breakage/thermal shock. Such a schedule would cause much all over surface distortion and loss of detail.. It sounds like the best solution is more coldwork polishing.

Re: drop ring fell off center

I agree with Brad and Jolly.. could be placement, glass color, etc.. etc. The keeping of records eg: firing time/temp., type and amount of glass, kiln placement etc. is the only way for you learn, move forward, and not repeat that which does not work! I have 2 binders (25 years) full of my firing re...

Kids plasticene in the Kiln?? I hope your kidding! You have a bit of a learning curve to get these numbers cast.

Re: enamel suggestions

I was able to get a watercolour look by mixing powder frit with "cable pull gel" (available at Home Depot) You wind up with a acrylic paint like consistency. Then apply to glass with brushes as if painting a watecolour . try it !!
