Remarks. 
Equally suitable for soft and hard woods. 
Has an excellent gloss and, in appear¬ 
ance, is superior to all the other 
samples of varnish. Would make a 
useful thick varnish for furniture. 
Turns slightly brown in sun. 
Takes too long to dry, otherwise of 
very fair appearance. Turns quite 
brown in the sun. 
Takes too long to dry, otherwise of 
very fair appearance. Turns quite 
brown in the sun. 
Not much gloss and rather too thick ; 
turns brown when exposed for long 
periods to sunlight. 
Has a very good gloss and is very 
nearly as good as No. 1, but is slower 
in drying. Would make a useful 
varnish for furniture ; suitable for 
both soft and hard woods. Turns 
reddish brown in the sun. 
Fair appearance. Turns brown in the 
sun. 
No use to the cabinet-maker, as it 
blisters. (Probably due to turpentine 
getting into the sample.) 
Takes too long to dry. Turns brown 
in the sun. 
Thick but good appearance, and would 
probably make a good lacquer. 
Slightly affected by the sun. 
Too thick for hardwoods, of very good 
gloss, and would probably make a 
very fine lacquer. Not affected by 
the sun. 
Takes too long to dry and too thick to 
be of use for furniture, has a good 
gloss. Very slightly affected by 
the sun. 
A quick drier but lacks gloss ; would 
make a useful varnish. Very 
slightly affected by the sun.
