Luminaire - that’s lighting stuff up, that is


What better way to catch up with old favourite bits of Chatsworth than by dim lighting. Chatsworth at night, by fake candlelight to be exact. The luminaire event was all rather enchanting. The atmosphere was set when we drove up at 7 pm, in the cold and dark and were greeted by the blue frontage - pretty stunning. Teenager proclaims “well, I wont be wanting an ice cream!” 






We saw pots and paintings, flooring and ceilings, sculptures and trinkets, all carefully lit with candlelight. Very atmospheric, giving the idea of what it must have looked like before electricity. The main star of the show, however, was the gardens. The building looked stunning and we liked the lit pathways to take you along the recommended route through the gardens.


The fierce weather held off for our visit but we did shuffle off home for a welcome hot chocolate and to recreate the Chatsworth effect in the comfort of our own sitting room.

French Polish


I have been wondering what to blog about, my father passed away recently after a short illness. It was inevitable at some point, but the sense of loss is very great.

Sorting through his belongings, I found an article he wrote about French Polish. Who better to provide a guest blog than

Read it – you might learn something. It will be particularly interesting for people who grew up believing the French polisher would be able to save the piece of furniture a young man damaged at a house party whilst his parents were away…he would never have done it in time (yellow pages ad c.1989). I’d always had my doubts.

French Polish
By Alan Wilson
I’m unsure of the date

A handsome piece of old furniture attracts by its design and style. The mind is intrigued by the skill involved in its construction. The eye is delighted by the beauty of its timber and veneer and one's hand is drawn to caress the quality of its finish. The patina and beauty will have been brought to perfection by the art in application used by an old time craftsman using French Polish.

The modern craftsman seeking to achieve the same results turns again to these old materials and methods, scorning the ubiquitous spray gun. What then is this magical material? The name is odd as it is known in France as English Polish. It consists of two ingredients, a resin called shellac and industrial methylated spirits and pure alcohol.

Shellac the basic resin comes form India and neighboring areas. It is an exudation of the parasitic lac insect, which feeds on special host trees. The word lac means one hundred thousand and is an indication of the vast number of little workers needed to produce this special resin. The word lac now gives us the modern term lacquer, used to describe many wood finishes. The basic resin is stripped from the trees and, being thermoplastic, is melted then filtered.

Various types are received in this country of which orange, button and garnet are examples. Processed grades such as white (obtained by bleaching) and transparent where the natural wax has been filtered out are also available.

Orange shellac is used to make the traditional French Polish and is available in flake form. Button shellac, used in button polish, was originally supplied as pats of resin about three inches wide and about one eighth thick. Now it too comes in flake form. Both French and button polish are cloudy due to the natural wax present in the resin. Garnet  shellac, as the name suggests, is a very deep colour and gives a very hard finish.

The polish made by dissolving the resin in the meths is applied by the craftsmen using a specially made pad or fad. This is constructed using about a nine inch square piece of chamois leather or cotton drill that has been washed many times. Well-laundered laboratory coats were much sought after for this purpose. A piece of pear-shaped wadding is placed in the center and the two sides of the leather folded diagonally over it to form a mouse-like shape. The whole is soaked in the polish with the loose ends twisted to squeeze the excess liquid out of the pad as required. 

The pad was then evenly worked over the surface of the piece of furniture, pressure being exerted to bring out more liquid to keep the surface wet. When the entire panel had been adequately covered it was left to dry for at least 24 hours. This operation was then repeated until a good solid coat had been applied. Best results were obtained using a steady circular motion. Finally the fad was used with a very dilute polish or even just meths to even out the final finish.
 
There are, of course, many tricks of the trade used by individual polishers. The most common is to add about 1-2% linseed oil to the polish to act as a lubricant. Alternatively the end of the fad is occasionally dipped into the oil for the same purpose during the application.

The result after many days work was a piece of furniture with a superb finish where the where the natural beauty of the timber had been developed to the full.

Dad was a Fellow of the Royal Society of Chemistry from 1956. He worked as a paint chemist most of his life he did a fair amount of research into ‘green’ waxes and polishes.

He lived a full, long life and enjoyed the occasional whiskey.
