Once deadwood has been shaped to the designer's plan, the exposed area is treated with a bleaching preservative. The most common is a horticultural combination of lime and sulfur, available from many garden outlets. The preservative protects the wood from rot and pest infestation, and provides a uniform bleaching that resembles weathered, aged ...
Bonsai enthusiasts use undiluted lime sulfur to bleach, sterilize, and preserve deadwood on bonsai trees while giving an aged look. [5] Rather than spraying the entire tree, as with the pesticidal usage, lime sulfur is painted directly onto the exposed deadwood, and is often colored with a small amount of dark paint to make it look more natural.
This juniper makes extensive use of both jin (deadwood branches) and shari (trunk deadwood). Bonsai are carefully styled to maintain miniaturization, to suggest age, and to meet the artist's aesthetic goals. Tree styling also occurs in a larger scale in other practices like topiary and niwaki. In bonsai, however, the artist has close control ...

This product, known as "bleaching powder" or "chlorinated lime", it is used in many of the same applications as sodium hypochlorite, but is more stable and contains more available chlorine. It is usually marketed as a white powder that contains, besides the hypochlorite, also calcium hydroxide Ca(OH) 2 ("lime") and calcium chloride CaCl 2. [21]
The pulping liquor for most sulfite mills is generated by treating various bases (alkali metal or alkaline earth hydroxides) with sulfur dioxide: SO 2 + MOH → MHSO 3 MHSO 3 + MOH → M 2 SO 3 + H 2 O. Similar reactions are effected with divalent cations (Mg2+, Ca2+) and using carbonates in place of hydroxide.
A number of styles describe the trunk shape and bark finish. For example, a bonsai with a twisted trunk is nebikan (also nejikan (ねじ幹)), and one with a vertical split or hollows is sabakan. The deadwood bonsai styles identify trees with prominent dead branches or trunk scarring. [3]: 123–124 Trunk and root placement.
Hydrogen peroxide is sometimes used with oxygen in the same bleaching stage, and this give the letter designation Op in bleaching sequences. Redox-active metal ions, particularly manganese , Mn(II/IV), catalyze the decomposition of hydrogen peroxide, so some improvement in the efficiency of peroxide bleaching can be achieved if the metal levels ...
