Welcome to the May 2013 issue of Glass International.

This month's features include articles on Annealing, Furnace Design and Operation, Inspection and Plant Utilities.

The feature-length articles begin with a profile of the Owens-Illinois (O-I) Harlow plant written by Assistant Editor Nadine Firth.

CNUD-EFCO's R&D Manager Hans Strauven discusses The Benefits of Annealing Lehrs while E.W Bowman's John Hann talks about Annealing of Glass Containers and Holloware.

The Furnace Design articles are provided by Glass Service and Bock, who examines the question Should Regulating Transformers or Thyristor Controllers be used in the Glass Melt.
