Re: Dichoric & iridized

If you were familiar with the production of catspaw and the formulations of it, you would realize why it disappears when it is heated to fusing temps. It never ceases to amaze me the people that haven't taken the time to visit glass companies and get an education on how difficult it is to make and k...

Re: Dichoric & iridized

As a furnace worker I used to spray tin chloride quite often as many glassblowers have done. It requires you to create a chamber that is well ventilated/exhausted and if used properly and carefully is not that dangerous. Some people I know even used silver chloride and Fenton even used ferrous chlor...

Re: Effect of Samarium on kiln elements

according to what I have read samarium oxidizes at 150C,. I doubt it would have any effect on your kiln seeing as how it is such a very small amount, 1% of that thin coating on the glass has got to be almost indistinguishable.

Re: Glues and silicones

Lisa, it depends on where the piece is to be used and what type of joint is involved. For outdoor usage, I preferred Panacol VBB-1. for some interior pieces I used 6108 with good success.

Re: SSR question

don't dismiss putting a fan on them as well. In my experience, it helped a lot. Those small computer fans are very inexpensive and are well worth the effort to install.

Re: Using Rare Earth Oxides

It depends on what rare earth oxides you are referring to. Cerium is normally used as a polishing agent for glass primarily as a final polish. Other rare earths are used in a few glasses but are normally mixed into the batch before they are ever melted. As far as applications of rare earths to glass...

Re: shipping large glass on containers on ship

If your crate is wooden, make sure you have the proper wood as many countries regulate what woods they will allow into their country for fear of the wood containing latent larvae from in sects. If you can get someone with experience making international shipping crates to make the crates for you.

Re: Loose abrasives vs. bonded(pads,etc.)

Many people have changed to the bonded abrasives because you can use one or two laps and just change the discs very quickly. Having the loose abrasives requires you to have more machines, usually a dedicated machine for each grit or you spend a lot of time cleaning up when changing from one grit to ...

Re: making cabochon with coin inclusion?

I used to put copper pennies in bottles and paperweights when I had my furnace. I would make a small indentation/cup in the gather then insert the coin and attach a 2nd gather on the cup's edge to encapsulate the coin. For fusers I would try making a small cup shape and then put the copper penny in ...

Re: How to Tell Good Art from Bad?

A good read is "The Principles of Art" by R.G. Collingwood who wrote this in 1923 but still has a lot of relevance to this subject today.

Re: The right torch for bullseye rods

Dual is required, but it must be surface mix, not premix. I've been using a Nortel minor for many years and now have switched to a Bethlehem Alpha, You also have to have your flame adjusted correctly and work way out in the end of the flame.

Re: Homeowners' Insurance

as long as it is a commercially produced piece of equipment and the service, either gas or electric is done to code and by a licensed individual it should not be problem just as plugging in a 220V stove or gas stove.

Re: Too much chipping

check out the blades at www.lopacki.com . I've used them for years and he has some that are ultra thin and if sawed slowly will give very few chips if any. Dan's prices are very reasonable as well.

Re: Telescope mirrors

casting in boro may not be possible in an electric kiln powered with wire elements. The elements will only go to about 2175 before having serious failures. The boro usually has to be melted to about 2400 min. and some boros need to go hotter. That's why there are few people that do boro furnace work...

It can be done. I met a woman at an art fair about 10 years ago from Florida who used Kokomo exclusively for fusing.. As has been mentioned, test everything before getting too carried away with designs.
