250g Hemp Rosin
250g Hemp Rosin, also called colophony or Greek Pitch, is a solid to liquid form of Resin obtained from Hemp and some other plants, mostly Tree's so our 100% Hemp Rosin extract is a special product for the budding artist.
Rosin is an ingredient in printing inks, photocopying and laser printing paper, varnishes, adhesives (glues), soap, paper sizing, soda, sholdering fluxes, and sealing wax.
Rosin can be used as a glazing agent in medicines and chewing gum. It is denoted by E number E915. A related glycerol ester (E445) can be used as an emulsifier in soft drinks. In pharmaceuticals, rosin forms an ingredient in several plasters and ointments.
In industry, rosin is a flux used in soldering. The lead-tin solder commonly used in electronics has about 1% rosin as a flux core helping the molten metal flow and making a better connection by reducing the refractory solid oxide layer formed at the surface back to metal. It is frequently seen as the burnt or clear residue around new soldering.
A mixture of pitch and rosin is used to make a surface against which glass is polished when making optical components such as lenses.
Rosin is added in small quantities to traditional linseed oil/sand gap fillers, used in building work.
When mixed with waxes and oils, rosin is the main ingredient of mystic smoke, a gum which, when rubbed and suddenly stretched, appears to produce puffs of smoke from the fingertips.
Rosin is extensively used for its friction-increasing capacity in several fields:
- Players of bowed string instruments rub cakes or blocks of rosin on their bow hair so it can grip the strings and make them speak, or vibrate clearly.
- Extra substances such as water, beeswax, gold, silver, are sometimes added to the rosin to modify its stiction/friction properties, and (arguably) the tone it produces. Powdered rosin can be applied to new hair, for example with a felt pad or cloth, to reduce the time taken in getting sufficient rosin onto the hair. Rosin is often applied to the bow before playing the instrument. Lighter rosin is generally preferred for violins and violas, and in high-humidity climates, while darker rosins are preferred for cellos, and for players in cool, dry areas.
- There are also specific, distinguishing types for basses—for more see Bow music.
- Violin rosin can be applied to the bridges in other musical instruments, such as the banjo and banjolele, in order to prevent the bridge from moving during vigorous playing.
- Ballet, flamenco, and Irish dancing girls are known to rub the tips and heels of their shoes in powdered rosin to reduce slippage on clean wooden dance floors or competition/performance stages. It was at one time used in the same way in fencing and is still used as such by boxers.
- Gymnasts and team handball players use it to improve grip. Rock climber's have used it in some locations, but it fouls the rock, so usage is now highly discouraged.
- Olympic weightlifters rub the soles of their weightlifting boots in rosin to improve traction on the platform.
- It is applied onto the starting line of drag racing courses used to improve traction.
- Bull rider's rub rosin on their rope and glove for additional grip.
- Baseball pitcher's and ten-pin bowler's may use a small cloth bag of powdered rosin for better ball control.
- Rosin can be applied to the hands in aerial acrobatics such as aerial silks and pole dancing to increase grip.
- Fine art uses rosin for tempera emulsions and as painting-medium component for oil paintings. It is soluble in oil of turpentine and turpentine substitute, and needs to be warmed.
- In a printmaking technique, aquatint rosin is used on the etching plate in order to create surfaces in gray tones.
- In archery, when a new bowstring is being made or waxed for maintenance purposes, rosin may be present in the wax mixture. This provides an amount of tackiness to the string to hold its constituent strands together and reduce wear and fraying.
- Dog groomers use powdered rosin to aid in removal of excess hair from deep in the ear canal.
- Some brands of fly papers use a solution of rosin and rubber as the adhesive.
- Rosin is sometimes used as an ingredient in dubbing wax used in fly tying.
- Rosin is used hot to de-encapsulate Epoxy integrated circuits.
- Rosin can be mixed with beeswax and a small amount of linseed oil to affix reeds to reed blocks in accordions.
Rosin and its derivatives also exhibit wide ranging pharmaceutical applications. Rosin derivatives show excellent film forming and coating properties. They are also used for tablet film and enteric coating purpose. Rosins have also been used to formulate microcapsules and nano particles.
Glycerol, sorbitol, and mannitol esters of rosin are used as chewing Gum bases for medicinal applications. The degradation and biocompatibility of rosin and rosin-based biomaterials has been examined in vitro and in vivo.
Our Hemp Rosin can come in different forms to fit different product usage above, Hemp Rosin is superior to Tree Rosin, in liquid and solid form.
Sativa Hemp Rosin is the most expensive Rosin on the market, with good reason! pick the mixture that's best for you, from solid Rosin that requires heat to become flexible, to liquid Rosin from sticky to none sticky extract slip diluted Rosin.
Hemp (C Sativa L) Rosin is a gift to mankind, some say it was the key ingredient in Ambrosia the food of the Gods.
