Question to the experts ou there. I have the large radial slumper with the indentations around the outside. I just slumped a two layer system 96 bowl on the slumper. I slumped at 1225 for a 25 minute hold. The indentations are light rather than deep around the border. Would a higher temperature or a longer slump create more of a carved appearance from the mold? What is the correct temp and hold time for this mold. Thanks in advance.

yes,
your kiln, your time, your temp. Test.

Thanks Kevin. Was hoping someone climbed the mountain first and knew the way. Does leaving it on mold and retiring at longer time and temp work or start with new fused blank?

If it is this mold, I have found that the pattern is not carved deeply enough to make much of a difference in the finished piece:

It's a disappointment -- the mold looks so lovely just sitting there .

Heatwork is a function of both time and temperature. Also, it depends on your kiln construction and configuration.

So, you can raise the temp, hold longer, or both. Each has it's set of shit that happens when you do that. As Kevin says, nobody can tell you what will happen in your kiln. Test...

If you screw it up, you probably learn more than if you get it right. or almost right.

Bert,

You are probably right. Unfortunately, the mold might be the problem as previously stated. The mold I am using is exactly that one and the indentations might not be deep enough to carve the appropriate amount. Oh well, there's $25 down the drain. Can heat and hold overcome a poorly made mold?

Peter and Dana- Fuse your blank on cut fiber paper (see BE's kilncarving stuff) similar to Slump's mold pattern and then slump it on that miserable mold.

No need to use the miserable mold. Just fuse on fiber paper and slump on any mold you want. The fused design will remain.

this mold makes for a subtle effect, it looks best using cathedral or clear glass that you can see the design from the top other wise it is not very impressive as a design on the bottom ofa piece

Yes, I know about kiln carving and yes, of course, I have used it only with transparent glass.

The idea is nice -- It would be lovely if they had carved the design deeper.

I have been LMAO for days at this succinct summary of information from hundreds of books, articles and classes, and thousands upon thousands of posts. The sentence is too subtle for ROFLMAO.
