The onion peel is boiled in water for15 minutesto a weakpinkcolour.The solution is applied to wood, giving a faint yellow colour.
RECIPE 2: BARK STAIN
The bark to be used has to be gathered during the summer. The colour is extracted by pouring a 5% soda solution over the bark and letting it stand for four weeks. For 250-500 g bark, 250 g soda and 5 litres boiled water are used. After four weeks the mixture has a very strong smell, but after an hour's simmering the smell disappears.
A brown colour is achieved by using beech, apple and spruce bark and a yellow colour from poplar and cherry bark. The latter needs a 10% soda solution.
The bark of ash gives a grey-green colour, and birch gives an apricot colour using a 10% soda solution.
Beeswax is particularly suitable for the treatment of floors and bathroom walls. It fills cracks and pores in timber and prevents vermin from laying eggs. Wax is usually dissolved in mineral spirits or turpentine and can also be thinned out with linseed oil. It can be coloured with earth or mineral pigments. The wax is easy to clean, but does not have much resistance to water, so more hard-wearing surfaces should be saturated with oil first.
Beeswax is a renewable resource that creates no problems in its production or use. Organic solvents will be a health risk during application, and can even cause problems in the indoor environment for a short period after application. Re-use of treated materials, recycling, energy recycling and composting or dumping create no problems.
