Photos are louder than words

[Terredax]

I don't want to clutter the other thread.

I've always heard that photos speak louder than words.

So here are a couple of photos to show that the swirl comes from the method.

Polyester:
These were all poured immediately after the catalyst was added.
They all have swirl, and zero air inclusions, with zero pressure.
Different methods, produce different swirls, as can be seen.

The photos aren't the best, but show the swirl.
Yes, there is some dust, and reflections of the window blinds.

Nicely done !! . And a nice variety of colors !!

Are you saying that you did not use pressure in your casting process ? . Absolutely none ?

What brand of polyester resin ?

 

[Terredax]

I have never used pressure, or vacuum, in any of my personal casting.

For all of these, I used Silmar 41.

My preference is polyester. Urethane's invite a lot of variables, not to mention the additional cost.

Silmar is a different animal than Alumilite

You're correct. Alumilite has a shorter pot life.

As I stated... I prefer polyester. The same swirls can be had with urethane, but it has nothing to do with temperature.

When you are increasing the temperature 25 degrees in 7 minutes, that additional 10 degrees , to 110 degrees, will happen in approx. 3 minutes. You've already reached gel and it becomes impossible to remove air.

If one can not swirl resin immediately after combining either the two-parts (urethane), or catalyst (polyester), they can't claim to be a caster.
Just because someone can mix together some chemicals, and put it in a container, doesn't make them a caster. Just like placing ingredients in a bowl, doesn't make a chef.

Quite nice, John. Ernie has enticed me enough to try the PR and Chuck (dalecamino) has seen to it I will be forced to try. Did my first pour of a block before hitting the road this week. Will be interesting to see how it turned out when I get home tomorrow.

In the few alumilite pours I have made resin temperature/gel state is a "Youge" factor in getting swirls; method is important but the gel state IMO is a big player.

Eugene, I thought you use Alumilite in ALL your pours ???

The photos are gone?!?

 

[Woodchipper]

Yep, just two black icons that say the image is not available or no longer exists.

That IS all I use
