While one enantiomer may be a potent attractant, the opposite enantiomer may have no activity or may even be a repellent. Sex and the single beetle: single female, non-smoking, likes grain and dark corners.
Fused and kiln-formed glass sculpture. Fused glass is glass that has been fired (heat-processed) in a kiln at a range of high temperatures from 593 Â°C (1,099 Â°F) to 816 Â°C (1,501 Â°F). There are 3 main distinctions for temperature application and the resulting effect on the glass.
When broken, borosilicate glass tends to crack into large pieces rather than shattering (it will snap rather than splinter). The softening point (temperature at which viscosity is approximately 107.6 poise) of type 7740 Pyrex is 820 Â°C (1,510 Â°F). Borosilicate glass is less dense (about 2.23 g/cm3) than typical soda-lime glass due to the low atomic mass of boron.
