She has written for newspapers, magazines, online publications and sites.Brenner graduated from San Diego's Coleman College.Famous American clockmaker Seth Thomas began his career as an apprentice to renowned clockmaker Eli Terry in 1807, but by 1810, he had purchased the clock factory from Terry and had begun producing his own clocks.Identifying a vintage mantel pendulum clock by Seth Thomas is sometimes difficult since he often hid the pendulum behind a small wooden door or delicately painted glass.In the Qutb complex of Delhi stands one of the most curious metal objects in the world - the so called “Iron Pillar of Delhi”, which does not seem to rust, despite being over a thousand years old.The height of the pillar, from the top of its capital to the bottom of its base is 7.2 metres, of which 1.1 metre is underground.Based on scientific analysis, it has been shown that these three factors work together to form a protective passive layer of rust on the Iron Pillar of Delhi.As a result, the pillar does not undergo further corrosion, and appears to have not rusted over a thousand year.

The pillar's lower diameter is 420 mm (17 in), and its upper diameter 306 mm (12.0 in).

One theory suggests that from its original location, the pillar was moved and erected in the main temple at the fortress city of Lal Kot at Dhilli (modern Delhi) when it was developed by the Tomar king, Anangapala II, in A. This mosque was built on the base of a temple, albeit not the one where the pillar was erected.

Using archaeological evidence, and facts based on temple architecture, it has been proposed that the pillar was moved from the Tomar temple to its present location in front of the mosque in the Qutb Complex.

These include the iron pillars at Dhar, Mandu, Mount Abu, Kodochadri Hill, and iron cannons.

Hence, it may be said that the ancient Indian iron-workers were highly skilled at forging iron objects.
