In Topic: Any Experince Teaching Those With Special Needs ?

23 March 2015 - 06:12 PM

I appreciate the imput. Thanks pres. I understand about not starting this on a lark. The project is the entire camp. The vision is to welcome weekly a different group. One week it might be kids with cancer, the next kids with diabetes or autism spectrum disorder. The next week might be disabled vets, etc.

This has been a dream of mine for many years, yet I am very apprehensive. it is a huge project.....

In Topic: Gas Burner Question

21 March 2015 - 12:02 PM

I am reminded of the Eharmony TV commercial in which the owner guy says to the girl...... "Beth, Do you want fast or forever".
 
So re-worked a bit (a lot) here......... "Do you want good, or cheap?"
 
....
 
A good burner will "buy" you cheaper firing costs, more control over the kiln, and a higher percentage of firsts (assuming no operator error).
 
For that kind of design, go with commercial burners unless you have the time to study burner design, and have a well equipped shop to produce a quality product.
 
I'm also reminded of the saying "pay me now or pay me later".
 
best,

Can you give us your top 5 choices of "better to best" burners. Also comment on Flat burners, silicone carbide combustion tubes, high velocity burners....

In Topic: New Copper Carb A Way Different Color!

18 March 2015 - 11:52 PM

Trying to remember my geology, Malachite, Cu2Co3(OH)2, is a mint green and azurite,Cu3(CO3)2(OH)2 is bright blue. Both are forms of copper carbonate. The differences in color comes from the differences in % of each of these two. Of the two, azurite has more Cu per molecular weight. That would mean that the mint green color has more Cu by weight. It would make sense that glaze colors would change as well.

I went out to the garage and found this ore sample. The light green is malachite while the deeper blue is azurite. Both exist in the same ore sample.

Like always, test, test, test.

In Topic: *gasp* Handle Sacrilege!

Also, another reason I enjoy pulled handles, is because I get to demonstrate it straight-faced, to a group of teenagers, while watching them try to not laugh...[/quote]

If you wanted to make them laugh, cover it with a condom to dry. You could Segway into clay shrinkage at the same time....lol

In Topic: Quick Question: Progressing From Test Glaze Batches To Production Batches

11 February 2015 - 12:01 AM

I like base 10.
I mix up one paper coffee cup of test at 100grams. Then you can easily see what percentage of oxides, opacifiers, bentonite etc to add.
From 100 grams it's an easy jump to 1000 gr., which is an icecream pail. all you do is add zeros to all your ingredients.
Then, easy move to 10,000 grams which is a 5 gallon bucket.[add more zeroes]

TJR.




It's easier for me to work in base 10 also. I also get used 250 ml saline irrigation bottles from work. Instead of discarding the irrigation bottles, I take them home. They are perfect for 100 gm tests.
