There is no way to know exactly when to bend it. It comes with practice and feel. The best approach is to heat the glass tubing gradually, and begin applying pressure while turning the tubing in the fingers to keep it rotating. Eventually, you will begin to feel the tubing "give", and in a second or two, it will bend.
The Tempering of glass is done by firing the glass in a gas fired "oven"

What are things that don't bend?
An object which does not bend is said to be rigid.
What happens when light hits a bent piece of glass?
Some of the light is reflected off the glass at the same angle - in a manner and angle similar to that of a ball deflected off a surface at a similar angle. This is what happens when light reflects from car windows into our faces. Much of the light, however, will penetrate the glass, so that the light source is seen from the other side. Nevertheless, on contact with the glass, the light that penetrates will be refracted (bent) and travel through the glass at a different angle from that of its original contact with the glass; but once having travelled through the glass, it will leave at its original angle of contact. The amount of refraction depends on a number of factors, but especially, on the thickness of the glass and specific angle of contact involved. So, the light bends as it passes through the glass, but leaves at its original angle.
What makes a pole seem to bend when you put it in a glass of water?
The reason for the pole appearing bent when put inside a glass of water is refraction. When a ray of light travels through one medium to the other, it tends to bend or deviate from its original path. Thus a light ray in this case, travels from the air through water, and then again through air and reach the eyes. Thus, the light ray deviates from its original path causing this phenomenon.
What is million dollar bend in Adams clasp?
The bend given after forming the arrow head, it is very critical bend, wire may fracture during this bend.
What substance will break rather than bend?
Ice will break rather then bend
Does light bend when it reflects on glass?
no , and its not calld 'bend' its called 'reflected' but its like bend but ITS NOT :)
How do you bend glass tubes?
by melting them
Does a light ray bend if it enters a glass block perpendicularly?
No, a light ray does not bend when it enters a glass block perpendicularly. It will continue in a straight path without changing direction when entering the glass block at a 90-degree angle.
How do you bend wiper arms so they contact all of the glass?
One should not bend the wiper arms so as to contact all of the glass. Check for proper blade mounting instead. This will contact all of the glass.
Why does glass bend when heated?
Glass bends when heated because the heat causes the molecules in the glass to vibrate more rapidly, changing its structure. This change in structure leads to expansion, causing the glass to soften and bend. This effect is known as thermal expansion.
Does light bend at the surface or middle of a block of glass?
bend at surface and continued in the same direction in bulk of it...and again bend at emerging surface.........
How do you make glass bends?
To bend glass you need to heat it, bend it, then allow it to cool in a slow and controlled manner. If you're talking about glass beads it's a different story, although the cool slowly still applies.
When light moves from air to glass will it bend away from the normal or towards?
When light moves from air to glass, it will bend towards the normal. This is due to the increase in optical density as light enters the glass medium, causing it to slow down and change direction.
How do you know when to bend the glass tube?
You should bend the glass tube when it is heated evenly to a specific point, usually indicated by a color change from the heat. It is important to bend it slowly and steadily to avoid cracking or uneven shaping of the tube. A glassworking torch or flame is typically used for this purpose.
Glass causes light to bend more than air does?
That's correct. Glass has a higher refractive index than air, which means that light travels at a slower speed in glass compared to air, causing it to bend more when passing from air to glass. This bending of light is also known as refraction.
What happens when light is refracted through glass?
The light will bend into an angle because of the shape of the glass and the location from which the light is coming from.
How does light bend without any source?
It bends in water or a magnifying glass.
