Hexamine solid fuel tablets have long been a reliable and efficient source of heat for model steam engines. Their use is not only traditional but also practical, as they provide a clean, smokeless flame that does not leave residue on the models. However, recent regulatory changes threaten to ban their use due to environmental concerns. While we understand and respect the need for environmental protection, it is important to note that the impact of hexamine tablets used in this context is minimal compared to other sources of pollution. Furthermore, alternatives such as electricity or gas do not provide the same authentic experience cherished by hobbyists and educators alike. We urge regulators to reconsider this decision and allow for an exception in the case of model steam engines. Please sign this petition if you support our cause.
