Blood-red Stain.
Stain.—
| Crocus martis | 20 parts |
| Yellow ocher | 4 parts |
| Sulphate of iron | 10 parts |
| Red oxide of iron | 2 parts |
A still cheaper method is to put a slip or external coating upon the goods. The slip being quite opaque, effectively hides the natural color of the brick or tile upon which it may be used.
The process is to mix:
| Blood-red stain | 1 part |
| Good red clay | 6 parts |
Add water until the mixture becomes about the consistency of cream, then with a sponge force the liquid two or three times through a very fine brass wire lawn, No. 80, and dip the goods in the liquid as soon as they are pressed or molded.
Blue Paviors.
Stain For Blue Paviors.—
| Ground ironstone | 20 parts |
| Chromate of iron | 5 parts |
| Manganese | 6 parts |
| Oxide of nickel | 1 part |
