Who Beats Up Your Bostwick?

Definition of a Tough Consistency Instrument

Sometimes we encounter a product that is so simple and rugged that it would be tempting to deem it indestructible. Consider a stainless steel trough with a gate and etched numbers on the bottom. Seems simple and the stainless would make it tough, right? That is not the case, but it has survived nearly unchanged for more than 85 years.

When Do I Need a Consistometer vs. a Viscometer?

Posted by Art Gatenby on Nov 30, 2021 4:05:31 PM

One of the most frequently asked questions we get is, "How can I get a viscosity reading from the Bostwick Consistometer?" The answer is, "You can't." We've elaborated on this in other articles. We've even got a great infographic to explain the difference. With this article, I hope to advance the understanding of the difference between these concepts even further.

How Do I Set Up A Bostwick Consistometer?

Posted by Art Gatenby on Dec 20, 2019 2:45:00 PM

 

We get the same two questions almost every week about the CSC Bostwick Consistometer:

             1) What angle do I use to set it up?

             2) How do I level the Consistometer?

Principle of Operation

The principle of the CSC Bostwick Consistometer is based on the slump cone. In this procedure, a cone is filled with the material to be tested. It is then set on a level surface with the open area facing downward. The cone is pulled away and after a fixed time, the amount that the material slumped is measured.  The thicker the material, the less slumping occurs.

Abused Bostwick Consistometer -  Before and After

 

Which looks more durable to you?

The value of a Bostwick Consistometer is that it’s easy to use, which makes it simple to do repeatable testing. The Consistometer is made of stainless steel. One would think that this means a long and useful life. However, as I regularly discover, the real world often defies theory.

A Consistometer’s value is diminished if its leveling plate and screws get bent out of alignment. The story that follows tells how people in the real world handle, or mishandle, this instrument, and what can be done to save it.

I used to think that liquids were pretty simple things. Is that what you think too?

Not so fast. Let’s take a look at three properties of liquids and see if we change our view.
