I just now am getting really educated on my Bosch mixer. It has a makrilon bowl. Does anyone know what that is? It is a heavy duty hard plastic bowl but I was wondering what is special about it. The fact that it is heavy duty and hard.

Also, the owner's manual says it will whip 20 egg whites in 2 minutes. So that tells me I can whip egg whites in it. I did not think so because of it being plastic.

I am looking into getting a smaller metal bowl that is $70. Just to be sure I don't mess up the Italian BC.

Thanks for your help,

Well, this much I do know about makrilon, it is virtually unbreakable and it can withstand temperatures of 115C which converts to 239F so no worries about boiling water melting it.

Thanks Squirrelly! I just sent you a pm and I had no seen this post. Where did you get the heat factor info? I got the unbreakable part but not the heat info.

Just wanted to correct the temperature this product can withstand, the 239F was when used as a thin coating on a cooling system. It actually withstands much higher temperatures.

The plastic does not soften until it reaches 150 °C (converts to 302F) and burns only when heated to over 500 °C. It is non-toxic, can be pigmented in any color and is odorless. It acts as an insulator for electricity and heat and is also recyclable!

Yes, indeed. I orginally bought this mixer to make bread and it does a really good job. I had hesitated to buy the metal bowl because it expensive but the company has made a smaller bowl which would fit my purpose and be less money than buying another mixer. I pretty faithful to my Bosch.

FYI for any readers. I Have not made IBC in my Bosch because of the trace grease factor. I don't want to waste ingredients. I am not that worried about the heat factor at this point.

Try beating one egg white. It will be obvious if you have traces of grease in the bowl.

To get rid of the trace grease all you have to do is wash the bowl, rinse, then rinse/swirl or/wipe with vinegar. You can then rerinse with water. No need to buy any other bowls. Vinegar will cut the grease, no problem. If you still aren't convinced, fill the bowl up with vinegar and let it sit overnight (although this is not at all necessary), then rinse with water.

For 70$ you could buy a whole lot of vinegar...
