Hi Dave,

As some people reading this forum are not from USA nor Australia, it seems necessary to be cautious using "denaturated alcohol" : in Europe, denaturated alcohol has very different formulas according to the country it is sold. Read this :
In France and in United Kingdom, standard denaturated alcohol contains water for about 10%.
In France, the bottles marked "Alcool 95" are, in fact, denaturated alcohol with 10% water, as "" are calculated in volume and "%" in mass. The difference came from a physical property: when you mix 1 liter of water and 1 liter of alcohol, you don't have 2 liters but only about 1.9 liter.

So, to make a good shellac, you have to buy in France "Alcool vernir 99 " (English word for word "Alcohol for varnish 99") which is 5 to 10 times the price of standard denaturated. But with "95", it don't evaporate quickly enough, and with "90", there is so much water the shellac goes whitish.

I don't know what you have to buy in United Kingdom. In France, if you live in the South-West or in the North, it seems you can buy good denaturated alcohol in Spain or in Belgium.
