It is only recently (the first artificial dye was invented in 1857) that the textile industry has turned to synthetic dyes. Today, many craftspeople are rediscovering the joy of achieving colour through the use of renewable, non-toxic, natural sources. Natural dyes are inviting and satisfying to use. Most are familiar substances that will spark creative ideas and widen your view of the world. Try experimenting. Colour can be coaxed from many different sources. Once the cloth or fibre is prepared for dyeing it will soak up the colour, yielding a range of results from deep jew- el-like tones to dusky heathers and pastels. -

Star-K Kosher Certification - Kosher Consumer
Star-K Kosher Certification - Kosher Consumer back Facts on Wax: Are Vegetable and Fruit Waxes Kosher? Rabbi Dovid Heber, Star-K Kashrus Administrator You may notice at your favorite supermarket the following statement next to the prominent "Summer Fruits from California" banner: "Coated with food grade vegetable, petroleum, and/or shellac-based wax or resin to maintain freshness" on their favorite fruits and vegetables. What are waxes? Are there any Kashrus concerns? Let us examine some of the Kosher facts on wax. Waxes are not a new phenomenon, as they have been used domestically for over 60 years, on a wide variety of fruits and vegetables (see list). Waxes are derived from a variety of sources and are a cross combination of natural and synthetic ingredients. The most common primary wax ingredients are shellac, carnuba wax, or petroleum based wax. Less frequently used and more costly wax bases include beeswax and candelia wax. Shellac or lac resin is a product that is imported from India and is used in waxes for citrus fruits, apples and pears. It is a product that is derived from the secretions of the tiny lac insect. The lac insect secretes "lac-resin" from its glands onto a host tree. The resin is then gathered, crushed, sieved, washed and purified into food grade shellac. Horav Moshe Feinstein, zt'l explains in Igros Moshe Y.D. II 24 that shellac is Kosher. Rav Moshe zt'l discusses several reasons for this conclusion - most important the analogy between shellac - a secretion from a non-Kosher insect, and honey - a secretion from a non-Kosher insect. -

The Moisture-Excluding Effectiveness of Finishes on Wood Surfaces
United States Department of Agriculture The Moisture- Forest Service Forest Excluding Products Laboratory Research Paper Effectiveness FPL 462 of Finishes on Wood Surfaces William C. Feist James K. Little Jill M. Wennesheimer Abstract Permeability to water vapor is one of the more important properties affecting the performance of coatings and other wood finishes. Often, one of the main purposes of finishing wood is to restrict moisture movement from the surroundings. We evaluated the moisture-excluding effectiveness (MEE) of 91 finishes on ponderosa pine sapwood, using the Forest Products Laboratory method in which finished and unfinished wood specimens in equilibrium with 30 percent relative humidity (RH) at 80 °F are weighed before and after exposure to 90 percent RH at 80 °F. Finishes with the best MEE were pigmented, nonaqueous (solvent-borne) finishes. Two-component epoxy paint systems had MEE values greater than 85 percent after 14 days when three coats were put on the wood. Molten paraffin wax and a sheathing grade, two-component epoxy material with no solvent were the very best finishes found in this study for controlling moisture vapor movement into wood. The MEE is a direct function of the number of coats of finish applied to the wood (film thickness) and the length of time of exposure to a particular humidity. Only 11 finishes were found to retard moisture vapor movement into wood with any degree of success over the relatively short time of 14 days, and then only when two or three coats were applied. These studies include evaluations of MEE by finish type, number of coats, substrate type, sample size, and time of exposure, and describe the effect on MEE of repeated adsorption/desorption cycles. -

Keep speed low. 5. Don’t over sand especially on soft or open grain woods. What are the common Finishes? 1) Oil • Natural product extracted from walnut, linseed, Tung, soy bean, etc. • Polymerized oil is heated to about 500 degrees in absence of oxygen, dryers sometimes added. Goal is to dry faster • Provided a natural looking finish but limited protection 2) Shellac • Shellac is a resin secreted by the female lac bug on trees in the forests of India and Thailand. • Friction Polish – Shellac, Alcohol, Boiled Linseed Oil, Beeswax optional 3) Varnish • Synthetic product made by cooking a drying oil and add resin like urethane or Alkalyd. • Wiping Varnish – Varnish/thinner blend 4) Lacquer • Nitrocellulose lacquer is mostly solvent-based and comprised of plant-based substances like cotton, mixed nitric and sulfuric acids. 5) Wax • Beeswax, carnuba • Provides little protection but adds sheen and maintains natural color • Used as both a finish and a polish. -
A Review of Wood Biomass-Based Fatty Acidsand Rosin Acids Use In
polymers Review A Review of Wood Biomass-Based Fatty Acids and Rosin Acids Use in Polymeric Materials Laima Vevere *, Anda Fridrihsone , Mikelis Kirpluks and Ugis Cabulis Polymer Department, Latvian State Institute of Wood Chemistry, 27 Dzerbenes Str., LV-1006 Riga, Latvia; [email protected] (A.F.); [email protected] (M.K.); [email protected] (U.C.) * Correspondence: [email protected]; Tel.: +371-28869638 Received: 26 October 2020; Accepted: 14 November 2020; Published: 16 November 2020 Abstract: In recent decades, vegetable oils as a potential replacement for petrochemical materials have been extensively studied. Tall oil (crude tall oil, distilled tall oil, tall oil fatty acids, and rosin acids) is a good source to be turned into polymeric materials. Unlike vegetable oils, tall oil is considered as lignocellulosic plant biomass waste and is considered to be the second-generation raw material, thus it is not competing with the food and feed chain. The main purpose of this review article is to identify in what kind of polymeric materials wood biomass-based fatty acids and rosin acids have been applied and their impact on the properties. Keywords: crude tall oil; tall oil; fatty acids; rosin acids; polymer materials 1. Introduction The success of plastics as a commodity has been significant and polymer materials are a part of everyday life. The advantages of polymers over other materials can be attributed to their adjustable properties, low cost and ease of processing. Worldwide, the manufacturing of polymers grows every year, reaching almost 360 million tonnes in 2018 [1]. In the light of environmental challenges of the 21st century, the development of novel low-cost and scalable monomers from renewable resources is essential. -

Colophony (Rosin) Allergy: More Than Just Christmas Trees
Clinical AND Health Affairs Colophony (rosin) allergy: more than just Christmas trees BY LINDSEY M. VOLLER, BA; REBECCA S. KIMYON, BS; AND ERIN M. WARSHAW, MD Colophony (rosin) is a sticky resin derived from pine trees and a recognized cause of allergic contact dermatitis (ACD), a type IV hypersensitivity reaction.1 It is present in many products (Table 1) and is a common culprit of allergic reactions to adhesive products including adherent bandages and ostomy devices. ACD to colophony in pine wood is less common although has been reported from occupational exposures,2 as well as consumer contact with wooden jewelry, furniture, toilet seats, and sauna furnishings.3 We present a patient with recurrent contact dermatitis following exposure to various wood products over the course of one year.
