A retort and clamp or tongs.
no, you'll burn yourself
First, always point the test tube away from yourself and others to prevent any splattering of hot liquids. Second, use a test tube holder to handle the test tube as it becomes very hot, preventing burns.
to heat things up, to hold test tubes while the get heated (mostly to heat things up)
This is also iodine, as a gas.
No. A ringstand is a stand with a base with a large pole sticking out of it. that you can attach rings to. A wire mesh is usually placed on the ring for setting a beaker to be heated. A test tube clamp can be attached to the ring stand to hold a test tube, for say, heating it in a hot water bath.
with the pair of special tongs you shuld have. which grip
Wear goggles and a laboratory apron Hold the test tube with a test tube clamp not in your bare hand. If the liquid is nonflammable it may be heated in the flame of a Bunsen burner, otherwise a hot water bath over a hot plate may be more advisable. If heating in the flame of a Bunsen burner hold the test tube at an angle and move the tube in and out of the cool area of the flame. Alway point the opening of the test tube AWAY from yourself and others.
The test tube clamp was invented to securely hold test tubes in place, preventing them from falling or spilling chemicals during experiments. It allows for safe handling and manipulation of test tubes, especially when they need to be heated or stirred.
Because if the experiment being conducted in the test tube is explosive or very reactive then it can spit out stuff and this can be dangerous to your eyes or skin. so by pointing the test tube away then you won't harm anyone if anything spits out

This is a huge safety concern. When the reactants are being heated, a hotspot could cause an explosive bubble to form which may spray out. If someone is in that path, they could be burned or poisoned.
