![]() ![]() The potential for health effects depends on several factors including the amount of Radium present, amount of time spent near contamination, proximity to the source of radiation, and whether any shielding (e.g., concrete or lead that blocks radiation) is in place. Low levels of exposure to Radium are normal, and there is no evidence that exposure to low levels is harmful. The presence of Radium does not mean that adverse health effects are occurring or could occur. Higher doses of Radium have been shown to cause effects on the blood (anemia), eyes (cataracts), teeth (broken teeth), and bones (reduced bone growth). Exposure to Radium over a period of many years may result in an increased risk of some types of cancer, particularly lung and bone cancer. In general, the greater the total amount of your exposure to radiation from Radium, the more likely you are to develop an adverse health effect. The potential for health effects depends on the amount of radiation a person is exposed to. The majority of radon exposures in buildings are from radon coming up from the ground. It is important to note that radon, a byproduct of Radium, can be present in buildings, particularly in basements. You may be exposed to higher levels of Radium if you work in a specific job using these materials. High levels of Radium are typically found in waste from former Radium processing and manufacturing facilities, or at former manufacturing facilities that used Radium and have been improperly cleaned. It is present in soil, water, rocks, coal, plants, and even food. How can people be exposed to Radium?Įveryone is exposed to low levels of Radium because it occurs naturally in the environment. Radium was even used in medical applications during the 20th century. Radium was also used until the early 1970s in ”glow-in-the-dark” paints, e.g., for dials on clocks, and in other industrial applications such as instrument calibration. How was Radium commonly used?Īt the beginning of the 20th century, Radium was thought to have beneficial health properties and was often added to consumer products such as toothpaste, hair creams, and even food. Since then, many Wright molds have gradually been put back in production by the new owners.Radium is a radioactive substance found in nature that can have adverse health effects under certain conditions. Molds of LG Wright Glass were liquidated at auction in May 1999. It is located on the inside of the lid in the forehead area (see arrow, Fig. Although we knew the piece was marked, we couldn't find it we had to call Rosso's to ask them where the mark was placed. The Ross mark is extremely faint and very difficult to see. Rosso makes no glass itself but jobs out molds it owns to various glass factories. The R in keystone is the mark of Ross Wholesale Glass Co. The current vaseline version has no mark on the base but is marked with a molded R up inside the lid. Smith made earlier reproductions including purple slag with no mark on the base. No Atterbury originals have ever been documented in vaseline.Īll Atterbury originals are marked on the bottom of the base in molded letters "Pat appld for". The vast majority of Atterbury originals are in milk glass but other original colors include clear crystal and transparent blue. The original bull's head mustard jar from which Wright's mold was copied was made by Atterbury & Company which patented the design in July, 1888. New jars were available in either regular or satin finish wholesale price $13.50-$15.50. Ross Wholesale Glass used a bull's head mustard jar mold made for LG Wright to produce a jar in vaseline glass. New Bull's Head Mustard Jar in Vaseline Glass
