The economic term describes the rate at which products are manufactured would simply be "production rate", which in a market economy is determined mostly by the consumer demand.
Not really decorated in that sense as making them look "good" i guess, but they were mostly leather bound and covered in tar to help preserve the wood.

If we look at the five principles of Islam, or the five pillars or the five fundamentals, belief practically ends with the first pillar of Islam. In other words, that affirmation that Allah is the only deity and that Muhammad is his messenger. After that, everything is action, is practice. The other four, i.e., praying, fasting, paying the zakat -- what I call a social tax -- and the hajj, involve action. Muslims are very action-oriented.
