Prevent it by using kiln wash. Cheaper and effective.

. . . but if you consider that cost as advertising, resume enhancement, and a possible sale, it becomes bearable, especially at the start of their career.

Not to be too literal, but this is basic. Maybe you should take a course . . .

Isn't a temp of 1495 hot enough for any colors?
This schedule seems off to me

I take them to 1500 to be sure. Then I hold and look until done.
My schedule:

Full to 1500
Hold
Off

No problem, lots of information is a good thing.

Different colours have different hardnesses (for want of a better word) and may require more heat to break the surface tension and allow the glass to flow. Fire like colours together and watch until they round off. BTW, I would not call a stack of 3, 3/4" pieces a little dot. I would call 1, 1/...

I do 10, or so, without drying, and get multiple firings from the shelf. Ensure that you cannot see the colour of your shelf through the primer. But, big but, I don't have opaque colours on the shelf. The base of my work is either irid side down, clear, or transparent, and I don't go over 1450 on th...

"Factor 1: You're using remelts (pattern bars in this case) which contain a lot of hot colors--reds, yellows, oranges. If I'm going to have problems with a remelt, it will usually be right in the hot color areas, so now I routinely count that as one factor." The problem with the ROY colors...

. . . 1 hr 30 isn't long enough for annealing that size of a piece.

Size? You anneal for thickness, not size.

YES.

Yes.
Yes.
Yes.

Here's a couple from IKEA. BTW, there is absolutely no problem having a candle within a few inches of a sheetrock painted wall, I've done it for years.

"And now that I've answered your question, here's one for you: If you won a contest and were given your weight in your choice of pennies, nickels, dimes, quarters, half dollars or dollar coins, which would you want? (U.S coins, no Googling allowed!)"

So . . . what is the answer?

That is a classic annealing crack. You're going to have to experiment with your controls to achieve the temps you desire. It can be done many, of us did it for years, some people still do it without a controller. Practice with an empty kiln. Start with your switches on 1/2. Give it 15 min, record th...

More annealing. Your center is 5/8" thick. Give it 3 hours.

Only 5 miles? And you got to wear shoes?

Hand-me-down shoes. I got my sisters pink toe shoes.
Caused me some trouble in gym class . . .

Brock: A very simple trick to ensure success when slumping into bowl forms, is to start inside the mold. Place your blank down from the rim a little bit and that places the blank under compression helping it to slump evenly. I have a question....do you mean that the glass should be smaller than the...

Check to see if the wheels have crowned. Turn it on, listen for ominous sounds.
