HOW WE MAKE TIGER'S EYE:
Hartmann modification without Creolin
Take 25 grams of lime water and bring to a boil with 25 grams of potash until dissolved (I use a microwave and small jelly jars and it takes about 1 1/2 minutes). Allow to cool, slightly, then add 2 grams pulverized alum (it will fizz a little, but nothing more than that) and stir well.

Take 1/4 tsp Lamp Black, add 1/4 - 1/2 tsp of the above mixture (start with the lower amount), 1/4 tsp water, and 1 drop of gall (some adjustment of these may be necessary).

Make a test base pattern on the size, such as the gelgit, and then throw a few small spots of the mixture on the size to watch the spread. Add additional gall, drop by drop, until the desired spread and ray formation appears. The thicker the mixture, the darker the central eye, but the more fragile it is. Additional water and gall can be added at this point to obtain the effect desired.
