(hint #1) Being able to play whatever I want has been a central theme to my own discovering how to play guitar. I've been on that path for 37 years, and it's enabled me to uncover, test and refine a unique, skill generating learning approach.
It is important to note that urethane foam is most commonly used to refer to a material made from polyurethane. The urethane reference in this name is to the type of links, also known as carbamates, that join the units in polyurethane.
What is butane? Butane is a hydrocarbon and a highly flammable, colourless, odourless, easily liquefied gas. It is typically used as fuel for cigarette lighters and portable stoves, a propellant in aerosols, a heating fuel, a refrigerant, and in the manufacture of a wide range of products. Butane is also found in Liquefied Petroleum Gas (LPG). Since 1987, hydrocarbons have replaced chlorofluorocarbons (CFCs) as the propellant used in most aerosols. Butane is one of the commonly used propellants in household and industrial aerosols and therefore can be found in numerous aerosol products. However, the packaging of many aerosols products will commonly identify the propellant as âhydrocarbonâ, not specifically identifying butane.
