According to Wikipedia: Porcelain enamel coatings on aluminium substrates may be fired at temperatures as low as 530Â°C. I'm pretty sure an electrical stovetop does not reach temperatures even half that high, so it must have been some sort of low quality enamel. Views.
The thyroid gland, or simply the thyroid /ËÎ¸aÉªrÉÉªd/ , is one of the largest endocrine glands in the body, and consists of two connected lobes.It is found in the neck, below the laryngeal prominence (Adam's apple).yperthyroidism occurs when the gland produces excessive amounts of thyroid hormones, the most common cause being Graves' disease âan autoimmune disorder. In contrast, hypothyroidism is a state of insufficient thyroid hormone production.
The term non-toxic goiter refers to enlargement of the thyroid that is not associated with overproduction of thyroid hormone or malignancy. The thyroid can become very large so that it can easily be seen as a mass in the neck. This picture depicts the outline of a normal size thyroid in black and the greatly enlarged goiter in pink. There are a number of factors that may cause the thyroid gland to become enlarged. A diet deficient in iodine can cause a goiter, but this is rarely the cause because of the readily available iodine in our diets. A more common cause of goiter in America is an increase in thyroid stimulating hormone (TSH) in response to a defect in normal hormone synthesis within the thyroid gland. The thyroid stimulating hormone comes from the pituitary and causes the thyroid to enlarge. This enlargement usually takes many years to become manifest.
