MANUFACTURE OF LUMINOUS PAINTS OR COLOURS, a communication to me from
abroad by Gustav Schatte, of Dresden in the Kingdom of Saxony
This invention has for its object to produce durable white or coloured paints,
which are mixed with a luminous substance or substances causing the mixture to
shine in the dark without altering the tint of the paint in day light. For this
purpose Zanzibar or Cowriecopal is melted over a charcoal fire, 15 parts of this
melted mass are dissolved in 60 parts of French turpentine, the resulting mixture
is filtered after which 25 parts of pure, boiled and iodised linseed-oil are added.
This varnish is carefully treated in a paint-mill with granite rollers and worked
into luminous paint by one of the following processes :-
1.) The pure white luminous paint is produced by mixing 40 parts of lake
varnish produced as described with 6 parts of prepared baric sulphate, 6 parts of
prepared calcic carbonate, 12 parts of prepared Zinc sulphide-white and 36 parts of
calcic sulphide, in an oil vessel and therein worked into a raw emulsion or broth
which is then ground fine between the rollers.
2.) To produce a red luminous paint 50 parts of the said lake varnish are mixed
with 8 parts of prepared baric sulphate, 2 parts of prepared madder-lake, 6 parts
of prepared realgar (red sulphuret of arsenic) and 34 parts of calcic sulphide and
the mixture worked in the same way as described for the white colour.
3.) To produce a luminous orange colour, 46 parts of prepared lake-varnish are
mixed with 175 parts of prepared baric sulphate, 1 part of prepared Indian yellow
(laune indien) 15 parts of prepared madder-lake, 35 parts of calcic sulphide.

page_text: 4.) To produce a luminous yellow colour or paint 48 parts of prepared lake-
varnish are mixed with 10 parts of prepared baric sulphate, parts of prepared
baric chromate, 34 parts of calcic sulphide.
5) To produce a luminous green colour or paint, 48 parts of prepared lake-
varnish are mixed with 10 parts of prepared baric sulphate, 8 parts of chromo
oxide-green, 34 parts of calcic-sulphide.
6.) A luminous blue colour is produced with 42 parts of prepared lake varnish,
10-2 parts of prepared baric sulphate, 64 parts of ultramarine blue, 5.4 parts of
cobalt blue, 36 parts of calcic sulphide.
7.) A luminous violet is produced with 42 parts of prepared lake-varnish,
10.2 parts of prepared baric sulphate, 2.8 parts of ultramarine violet,.9 parts of
cobaltous arsenate, 36 parts of calcic sulphide.
8.) A luminous grey colour or paint is produced with 45 parts of prepared lake-
varnish, 6 parts of prepared baric sulphate, 6 parts of prepared calcic carbonate,
05 parts of ultramarine blue, 65 parts of zinc sulphide grey, 36 parts of calcic
sulphide.
9.) A yellowish brown paint is obtained with 48 parts of prepared lako-varnish,
10 parts of prepared baric sulphate, 8 parts of orpiment, 34 parts of calcic
sulphide.
10.) Luminous colours for artists may be manufactured, if in the mixture
described under 1 to the respective parts of lake-varnish afo replaced by the
same quantities of East Indian poppy-oil and the product is then finely ground and
prepared.
11.) Luminous colours for oil-printing may be produced by using instead of the
above mentioned parts of lake-varnish the same quantities of pure linseed oil won
by presses only.
12.) All the paints described under 1 to 9 may be made into luminous colours
for coloured paper if the lake-varnish is omitted and the thus won dry luminous
colours are ground or mixed with water, and some binding substance free of acids.
13.) All the paints mentioned under 1 to 9 may be made into luminous wax
colours for casting on hollow glass-ware and similar objects, if instead of the lake-
varnish composed as described 10 per cent more of cern-japonica and the fourth
part of the latter quantity of oleum olivarum alb., is used.
14.) All the paints described under 1 to 9 may be made into colours for painting
on porcelain, the incineration being effected with the exclusion of air.

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent, and of
an Order of the Lord Chancellor, filed by the said Herbert John Haddan in
the Great Seal Patent Office on the 10th July 1883.
HERBERT JOHN HADDAN, of Kensington, Middlesex, "IMPROVEMENTS IN THE
MANUFACTURE OF LUMINOUS PAINTS OR COLOURS," a communication to me from.
abroad by Gustav Schatte, of Dresden, in the kingdom of Saxony
The luminous calcic sulphide (also called sulphide of calcium) now obtainable in
the market, has a yellowish-white tint, which considerably limits its direct
application as a paint.
On the other hand, the calcic sulphide, or the luminous paint obtained therefrom,
loses its. luminous property, if it is directly mixed with the ordinary.commercial
paints.
The present invention has for its object to produce durable white or coloured
paints, containing a luminous substance, which causes them to shine in the dark,
without changing or neutralizing in daylight the tint of the colouring substance or
substances contained in such paints.
For this purpose Zanzibar or Cowrie-copal is melted over a charcoal fire, 15 parts
of this melted mass are dissolved in 60 parts of French turpentine and the resulting
mixture is filtered, whereupon 25 parts of pure linseed oil are added, which linseed
oil has been previously boiled and allowed to cool a little.
The lake varnish thus obtained is carefully treated in a paint-mill with granite
rollers and worked into a luminous paint by one of the processes hereinafter
described.
Iron rollers capable of giving off under great pressure small particles of iron
which might affect the luminous power, should not be used.
Lake varnish as obtained in commerce contains nearly always lead or manganese
which would destroy the luminous power of the calcic sulphide.
1. A pure white luminous paint is produced by mixing 40 parts of lake varnish
obtained as described with 6 parts of prepared baric sulphate, 6 parts of prepared
calcic carbonate, 12 parts of prepared Zinc sulphide-white and 36 parts of calcic
sulphide in a luminous condition, in an oil vessel and therein worked into a coarse
emulsion or broth which is then ground fine between the rollers.
2. To produce a red luminous paint 50 parts of the said lake varnish are mixed
with 8 parts of prepared baric sulphate, 2 parts of prepared madder-lake, 6 parts of
prepared realgar (diarsenious disulphide) and 34 parts of calcic sulphide in a
luminous condition and the mixture worked in the same way as described for the
white colour.
3. To produce a luminous orange colour, 46 parts of prepared lake varnish are
mixed with 17.5 parts of prepared baric sulphate, 1 part of prepared Indian yellow
(Iaune indien), 1-5 parts of prepared madder-lake, and 35 parts of calcic sulphide
in a luminous condition.
4. To produce a luminous yellow colour or paint 48 parts of prepared lake-varnish
are mixed with 10 parts of prepared baric sulphate, 8 parts of prepared baric
chromate and 34 parts of calcic sulphide in a luminous condition.
5. To produce a luminous green colour or paint, 48 parts of prepared lake-varnish
are mixed with 10 parts of prepared baric sulphate, 8 parts of chrome oxide-green
and 34 parts of calcic-sulphide in a luminous condition.
6. A luminous blue colour is produced with 42 parts of prepared lake-varnish,
10-2 parts of prepared baric sulphate, 6.4 parts of ultramarine blue, 5.4 parts of
cobalt blue and 36 parts of calcic sulphide in a luminous condition.

page_text: 7. A luminous violet is produced with 42 parts of prepared lake-varnish,
10-2 parts of prepared baric sulphato, 2:8, parts of ultramarine violet, 9 parts of
cobaltous arsenate and 36 parts of calcic sulphide in a luminous condition.
8. A luminous grey colour or paint is produced with 45 parts of prepared
lake-varnish, G parts of prepared baric sulphate, G parts of prepared calcic
carbonate, 05 parts of ultramarine blue, 65 parts of zinc sulphide grey and
36 parts of calcic sulphide in a luminous condition.
9. A yellowish brown paint is obtained with 48 parts of prepared lake-varnish,
10 parts of prepared baric sulphate, & parts of orpiment and 34 parts of calcic
sulphide in a luminous condition.
10. Luminous colours for artists may be manufactured, if in the mixtures
described under 1 to 9 the respective parts of lake-varnish are replaced by the
same quantities of pure East Indian poppy-oil and the product is then finely.
ground and prepared.
11. Luminous colours for oil-printing may be produced by using, instead of tho
above mentioned parts of lake-varnish, the same quantities of pure linseed oil won
by presses only, and thickened by boiling:
12. All the paints described under 1 to 9 may be made into luminous colours
suitable for making coloured paper and other purposes if the lake varnish is
omitted and the thus won dry luminous colours are ground or mixed with water,
and some binding substance free of acids.
13. All the paints mentioned under 1 to 9 may be made into luminous wax
colours for casting on hollow glass-ware and similar objects, if, instead of the lake-
varnish composed as described, 10 per cent more of cera-japonica and the fourth
part of the latter quantity of oleum olivarum alb., is used.
14. All the paints described under 1 to 9 may be made into colours for painting
on porcelain, by following the direction given under N° 11. The colour is painted
on porcelain and then incinerated with the exclusion of air. The paints may also
be treated with soluble glass (potash and soda water glass).
In all these cases (10 to 14) the advantage of shining in the dark, without
changing tho tint of the different colouring matters in normal light, is retained.
Having now described the invention I wish it to he understood; that I do not
limit myself to the exact proportions stated, as the same may be varied according to
the quality of the materials used, or the shades required, without departing from
the invention, but that what I claim is:
1. The manufacture of luminous paint of red, orange, yellow, green, blue, violet,
grey or brown colour in various shades, as well as of white luminous paint, by the
methods substantially as described under N° 1 to 9.
2. The manufacture of luminous artists' colours, colours for oil printing, or for
inaking coloured papers, as well as wax and porcelain colours in pure white, or in
various shades of red, orange, yellow, green, blue, violet, grey, or brown according
to the methods substantially as described under N° 10 to 14.
In Witness whereof I, the said Herbert John Haddan, have hereunto set my
hand and seal this 10th day of July A.D. 1883.
