Review of Kevlar Spark Resistant Apron by Magid Glove and Safety
I have been asked to do a review of a heat resistant apron for use in blacksmithing.
You can see it in the photo. It has full coverage and is quite light material. There are cross over straps that are quite comfortable and easy to adjust for sizing. It is also easy to get into and out of.
I am not a huge fan of the color but in a blacksmith shop that will change.
The traditional leather apron is used to deflect sparks or falling hot metal away from your body. Leather is quite durable and will take a beating. But in cold weather (as you see I am wearing my hat as it was chilly today in the shop) leather stiffens up and you practically have to thaw it out.
With this apron it was soft and pliable all the time. A nice bonus.
So How did I test this apron out? Well I simply stretched the fabric across an opening and secured it with two magnets.
I then heated a 3/8ths square bar about 3 inches long to about 1800 degrees F. See the photo on the left.
I then placed the hot bar on the fabric and watched what happened.
So it turns out that after about 3 seconds the heat transfers through the fabric and scorches the underside. Now this means that if you were inc contact with the hot steel for 3 seconds you probably would get burned.
But after smoking a bit (stinks a bit too) the bar was still well supported after 15 seconds. This means that the fabric was still intact after 15 second direct exposure to 1800 degree heat.
Now in the greater schem of things 3 seconds is a long time to have something hot brush up against you in blacksmithing. 15 seconds is an eternity.
So my feeling is this is a good product for general protection.
You can see the smoke in this photo.
This final photo shows the scorch mark. Not bad for 15 second exposure.
