Happy cooking.
Where have you used it, and what did you &quot;cook&quot; ?<br>I really don't understand how I should be able to make feks, Tea. <br>The water should get up to nearly cooking temperature, and I doubt that this can.<br>How long time will it take to heat a cup of soup, and how hot will it be? <br>
<p>How long does it take to reach 150F, the temperature water is pasteurized at?</p>
<p>How hot does it get?</p>
With the help of the reflectors the heat will concentrate at the center where the glass is located. <br>The darker the glass the better. In this example, I used the beer bottle so painting of the glass is not necessary.
